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.

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 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.
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 troubleshooting information has been further fine-tuned to
report popup panel data related to the reported page, for better
diagnosis by disclosing any customization to uBO which was
affecting the reported page.

A "chat" icon has been added to the popup panel to make
it easy to report filter issue on specific sites.
Reporting filter issues require a GitHub account, since
uBO does not have a home server through which reports could
be sent.
The report icon is available only for when uBO is enabled
on a given site.
On mobile devices, the logger icon is replaced by the "chat"
icon since it is more likely to be useful on small display
devices. The logger can always be opened from the Support
pane in the dashboard.

- Autofill issues opened through Support pane with configuration
information
- Remove from About pane items found in Support pane
For now the language locales are not available as the text on
the page needs to stabilize before asking translation
volunteers to contribute their time working on the new text.
The code exported to nodejs package was revised to use modern
JavaScript syntax. A few issues were fixed at the same time.
The exported classes are:
- DynamicHostRuleFiltering
- DynamicURLRuleFiltering
- DynamicSwitchRuleFiltering
These related to the content the of "My rules" pane in the
uBlock Origin extension.

The various filtering engine benchmarking functions are best
isolated in their own file since they have specific
dependencies that should not be suffered by the filtering
engines.
Additionally, moved decomposeHostname() into uri-utils.js
as it's a hostname-related function required by many
filtering engine cores -- this allows to further reduce
or outright remove dependency on `µb`.

The changes are enough to fulfill the related issue.
A new platform has been added in order to allow for building
a NodeJS package. From the root of the project:
./tools/make-nodejs
This will create new uBlock0.nodejs directory in the
./dist/build directory, which is a valid NodeJS package.
From the root of the package, you can try:
node test
This will instantiate a static network filtering engine,
populated by easylist and easyprivacy, which can be used
to match network requests by filling the appropriate
filtering context object.
The test.js file contains code which is typical example
of usage of the package.
Limitations: the NodeJS package can't execute the WASM
versions of the code since the WASM module requires the
use of fetch(), which is not available in NodeJS.
This is a first pass at modularizing the codebase, and
while at it a number of opportunistic small rewrites
have also been made.
This commit requires the minimum supported version for
Chromium and Firefox be raised to 61 and 60 respectively.

The element picker will now properly work on sites where
cosmetic filtering is disabled, but will not allow the
creation of cosmetic filters when specific cosmetic filters
are not meant to be enforced in the current page.
When specific cosmetic filters are not meant to be enforced,
the element picker will still allow the creation of network
filters, that is unless the current page is trusted, in which
case using the element picker is pointless.
The syntax to remove response header is a special case
of HTML filtering, whereas the response headers are
targeted, rather than the response body:
example.com##^responseheader(header-name)
Where `header-name` is the name of the header to
remove, and must always be lowercase.
The removal of response headers can only be applied to
document resources, i.e. main- or sub-frames.
Only a limited set of headers can be targeted for
removal:
location
refresh
report-to
set-cookie
This limitation is to ensure that uBO never lowers the
security profile of web pages, i.e. we wouldn't want to
remove `content-security-policy`.
Given that the header removal occurs at onHeaderReceived
time, this new ability works for all browsers.
The motivation for this new filtering ability is instance
of website using a `refresh` header to redirect a visitor
to an undesirable destination after a few seconds.

Prior to this commit, the ability to enable/disable the
uncloaking of canonical names was only available to advanced
users. This commit make it so that the setting can be
toggled from the _Settings_ pane.
The setting is enabled by default. The documentation should
be clear that the setting should not be disabled unless it
actually solves serious network issues, for example:
https://bugzilla.mozilla.org/show_bug.cgi?id=1694404
Also, as a result, the advanced setting `cnameUncloak` is no
longer available from within the advanced settings editor.

Exception filters for `document` option are complying with
uBO's own semantic for `document` option, i.e. an exception
filter for `document` option will only allow to bypass a
block filter for `document` (either explicit or implicit)
and nothing else.
Exception filters using `document` option are *not*
compatible with ABP's interpretation of these filters.
Whereas in ABP the purpose of a `document` exception filter
is to wholly disable content blocking, in uBO the same
filter will just cause strict-blocking to be disabled while
leaving content blocking intact.
Additionally, the logger was fixed to properly report pages
which are being strict-blocked.
The procedural cosmetic filtering code has been split from
the content script code injected unconditionally and will
from now on be injected only when it is needed, i.e. when
there are procedural cosmetic filters to enforce.
The motivation for this is:
https://www.debugbear.com/blog/2020-chrome-extension-performance-report#what-can-extension-developers-do-to-keep-their-extensions-fast
Though uBO's content script injected unconditionally in all
pages/frames is relatively small, I still wanted to further
reduce the amount of content script code injected
unconditionally: The procedural cosmetic filtering code
represents roughly 14KB of code the browser won't have to
parse/execute unconditionally unless there exists procedural
cosmetic filters to enforce for a page or frame.
At the time the above article was published, the total
size of unconditional content scripts injected by uBO was
~101 KB, while after this commit, the total size will be
~57 KB (keeping in mind uBO does not minify and does not
remove comments from its JavaScript code).
Additionally, some refactoring on how user stylesheets are
injected so as to ensure that `:style`-based procedural
filters which are essentially declarative are injected
earlier along with plain, non-procedural cosmetic filters.

Additionally, a small (experimental) widget has been added
to emphasize/de-emphasize rows which have 3rd-party
scripts/frames, so as to more easily identify which rows
are "affected" by 3rd-party scripts and/or frames.
Tooltip localization for the new widget is not available
yet as I want wait for the feature to be fully settled.

Forward compatiblity was broken due to `externalLists`
being converted into an Array from a string, i.e.
downgrading to uBO 1.32.4 was completely breaking uBO.
This commit restores `externalLists` as a string which
is what older versions of uBO expect.
A new property `importedLists` has been created to
hold the imported lists as an array, while
`externalLists` will be kept around for a while until
it is completely removed in some future.
The managed `userSettings` entry is an array of entries,
where each entry is a name/value pair encoded into an array
of strings.
The first item in the entry array is the name of a setting,
and the second item is the stringified value for the
setting.
This is a more convenient way for administrators to set
specific user settings. The settings set through
`userSettings` policy will always be set at uBO launch
time.
Content scripts can't properly look up effective context
for sandboxed frames. This commit add ability to extract
effective context from already existing store of frames
used for each tab.
The entry `toOverwrite.filterLists` is an array of
string, where each string is a token identifying a
stock filter list, or a URL for an external filter
list.
This new entry is to make it easier for an
administrator to centrally configure uBO with a
custom set of filter lists.
