If the removed stock list is labelled a "bad list", do not
convert it into an imported list.
This will allow to seamlessly merge resource-abuse stock list
with privacy stock list when 1.42.0 is widespread.

The value 0xFFFFFFFF will be used instead of 0 to mark the end of
a sequence of tokens, as the value 0xFFFFFFFF can't happen as a
result of computing a token hash, since the four most significant
bits are always 0 in a computed token hash.

The code was testing only the LSB of a 32-bit integer to detect
whether the current rule was a wildcard (`*`), while it had to
compare against the whole 32-bit integer.
The breakage occurred when the LSB of an offset to the character
buffer happened to match the ASCII code of `*` (42, 0x2A).
(An offset is used when a label is longer than 4 characters)
The purpose of this new procedural operator is to target
all elements _outside_ than the currently selected set of
elements.
For any element feeding into `others()`, the resultset
of the `others()` operator will include everything else
except:
- the descendants of a subject element
- the ancestors of a subject element
The resultset will contains the siblings of a subject
element _except_ when those siblings are either a
descendant or ancestor of another subject element.

Though this operator is unlikely to be used in default lists,
it opens the door to create specialized filter lists which
purpose is some sort of "reader mode", where everything
_else_ than a selected set of elements are hidden from view.
Examples of usage:
twitter.com##:matches-path(/^/home/) [data-testid="primaryColumn"]:others()
nature.com##:matches-path(/^/articles//) :is(.c-breadcrumbs,.c-article-main-column):others()
The status is currently considered experimental and support
might be removed in the future if it turns out there is no
sufficient usage or if unforeseen difficult issues arise
implementation-wise.
The Create button was being unduly enabled for a fraction of
second while editing the content of the filter text.
This commit is candidate for a revision to current stable

From what I gather looking at Firefox for Android, a
period is used in a sentence only when there were
prior usage of punctuation in the descripton, i.e.
a comma, or a a period in a previous sentence. Single
standalone sentence should not have a trailing period.
Additionally, have a list of preset colors for the color
picker (unlike Firefox, Chromium's built-in color picker
does not have a list of preset colors by default).
uBO will use the information from prefers-color-scheme to reduce
likelihood of background color flash. However this works only for
when prefers-color-scheme is properly set by the browser, and only
when uBO's theme selection is "auto", or when it happens to
match that of prefers-color-scheme.

Too many changes to list here, essentially there is now a
user interface setting to enable/disable dark theme, and
I've rearranged a bit the Settings pane as a result and
also altered other visuals in various places.
There are places which I know have not been thoroughly
tested (i.e. logger inspector).
Will fine-tune as per feedback.
Issues with the classic popup panel will not be addressed,
and if feedback is that it has become unusuable, it will be
outright removed.
Reported internally.
The issue involves `removeparam` filters with a regex value. When
such filter was visited before a selfie was created, this would cause
the created selfie to persist a RegExp object, which can't be
serialized. This would cause exceptions to be thrown when uBO would
be subsequently loaded with the tainted selfie, since uBO would try
to execute a plain Object as a RegExp.
This will allow to find out what is specifically blocked on the
page reported as having issues, potentially saving time
when volunteers try to diagnose issues.

In above related commit, uBO was modified to cache the URL of the
last clicked link, and to use this cached URL to test for the
legitimacy of the newly opened tab.
The current commit add back a test against the URL of the last
clicked link to avoid false positives when navigating from within
the newly opened tab.

The new setting, when disabled (enabled by default), allows a user
to prevent uBO from waiting for all filter lists to be loaded
before allowing network activity at launch. The setting is enabled
by default, meaning uBO waits for all filter lists to be loaded in
memory before unsuspending network activity. Some users may find
this behavior undesirable, hence the new setting.
This gives the option to potentially speed up page load at launch,
at the cost of potentially not properly filtering network requests
as per filter lists/rules.
For platforms not supporting the suspension of network activity,
the setting will merely prevent whatever mechanism exists on the
platform to mitigate improper filtering of network requests at
launch. For example, in Chromium-based browsers, unchecking the
new setting will prevent the browser from re-loading tabs for
which there was network activity while in "suspended" state at
launch.
As the trie is not immediately created, in order to speed up
launch time, the `domain=` option was stored in the filterRefs
array until it was moved to the trie.
This commit instead stores the `domain=` option into the trie
container's character buffer.
This commit will force-reload active tabs at launch for
environments not supporting suspend network request listeners,
or configured to not suspend network request listeners.
Refactored heuristics to collate set of origin-related
filter units are collated into a hostname trie, and
for better reuse of existing classes.
Generalized pre-test idea for bucket of filters, such
that in addition to origin-related filter units, there is
now a class to collate regex-based pattern-related units
into a new pre-test bucket class, FilterBucketIfRegexHits,
in order to test with a single regex test whether there is
a chance of a hit in the underlying bucket of filters.
Instances of these are rare, but at time of commit I found
this occurs with AdGuard France filter list.
Fine-tuned the "SNFE: Dump" output -- this new ability to
see the internal details of the SNFE has been really key
into finding/fixing issues during refactoring.
As was done with generic pattern-based filters, the source
string of regex-based filters is now stored into the
bidi-trie (pattern) buffer.
Additionally, added a new "dev tools" page to more
conveniently peer into uBO's internals at run time, without
having to do so from the browser's dev console -- something
which has become more difficult with the use of JS modules.
The new page can be launched from the Support pane through
the "More" button in the troubleshooting section.
The benchmark button in the About pane has been moved to this
new "dev tools" page.
The new "dev tools" page is for development purpose only,
do not open issues about it.
There are currently over 160 patterns with such pointless
trailing `*^` in uBO's filter lists, which ended up being
compiled as generic pattern filters (i.e. regex-based
internally), while the trailing `*^` accomplishes nothing
since it will always match the end of a URL ( `^` can
also match the end of URL).
This commit discards pointless trailing `*^` in patterns,
thus allowing most of those filters to be compiled as
plain pattern filters.
The syntax highlighter will reflect that a trailing
`*^` is pointless.
Rearrange logic to instantiate and add `important` filters
to the block realm when compiled lists are loaded instead
of when lists are compiled.
Additionally, removed now unused properties following
commit 68e14793cc.

As per internal discussion with team, best to have a simpler
scriplet, and which is hard-coded to work only on a specific
set of domains -- only those seen used by BAB.
Turns out the various benchmarks show no benefits when compiling
filters whose pattern contains a single wildcard character into
specialized classes which threat the pattern as two sub-patterns,
and actually there is a slight improvement in performance as per
benchamrks when treating these patterns as generic ones.
This also fixes the following related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1207
Fixed serious regression in previous dev build in applying
`csp=` filters. Reported internally by uBO team.
Promote usage of `removeparam` in code instead of `queryprune`,
which is to be deprecated.
Removed test against previously tested hostname in
FilterHostnameDict since as per various benchmark, the
test does not really help.
Remove serialization API in Node.js code as the API is now
present in SNFE itself.
All the auxiliary data structures must be fully loaded before
the data structure used as entry point is populated. The race
condition could lead to a case of the entry point data structure
being populated while the auxiliary data structures are still
unpopulated, potentially causing exceptions to be thrown at
launch when the static network filtering engine is queried.
I haven't been able to reproduce such exceptions -- but it
could happen on browsers which do not support being suspended
at launch time (i.e. chromium-based browsers).
Additionally, added convenience methods to easily
serialize/unserialize when SNFE is used as a npm package.

Through all the changes, forgot to pay attention to scenarios
where the `filterData` needs to grow -- the buffer's defautl
size is set to accomodate default filter lists, and subscribing
to more lists would cause the static network filtering engine
to fail because the buffer was not resized when needed.
The original motivation is to further speed up launch time
for either non-selfie-based and selfie-based initialization
of the static network filtering engine (SNFE).
As a result of the refactoring:
Filters are no longer instance-based, they are sequence-of-
integer-based. This eliminates the need to create instances
of filters at launch, and consequently eliminates all the
calls to class constructors, the resulting churning of memory,
and so forth.
All the properties defining filter instances are now as much
as possible 32-bit integer-based, and these are allocated in a
single module-scoped typed array -- this eliminates the need
to allocate memory for every filter being instantiated.
Not all filter properties can be represented as a 32-bit
integer, and in this case a filter class can allocate slots
into another module-scoped array of references.
As a result, this eliminates a lot of memory allocations when
the SNFE is populated with filters, and this makes the saving
and loading of selfie more straightforward, as the operation
is reduced to saving/loading two arrays, one of 32-bit
integers, and the other, much smaller, an array JSON-able
values.
All filter classes now only contain static methods, and all
of these methods are called with an index to the specific
filter data in the module-scoped array of 32-bit integers.
The filter sequences (used to avoid the use of JS arrays) are
also allocated in the single module-scoped array of 32-bit
integers -- they used to be stored in their own dedicated
array.
Additionally, some filters are now loaded more in a deferred
way, so as reduce uBO's time-to-readiness -- the outcome of
this still needs to be evaluated, time-to-readiness is
especially a concern in Firefox for Android or less powerful
computers.
Add ability to bring back logger button in popup panel through
the advanced setting `uiPopupConfig`. Adding `+logger` token
to `uiPopupConfig` will bring back the logger icon in the mobile
version of the popup panel.
Additionally, the link to the logger in the Support pane will
take into account whether the <Shift> key is pressed, so as
to behave like the logger icon in the popup panel.

The URL to report can now be picked from a list of related
URLs in order to allow the reporter to publish edited version
of the reported URL.
Additionally, the hash, user name, and password which could be
present in a reported URL are always removed.
Unredacted settings is unlikely to be useful after all,
and removing the ability to unredact ensure users won't
mistakenly publish unredacted information.
