The title of tabs in uBO is solely to have a better
presentation in the logger -- no other purpose.
This commit simplify keeping track of the titles, from
an active approach by directly querying it from tabs
whenever a change occurs, to a passive approach by
storing it when the title string become available in
some tab event handlers.

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.

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.
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.

The new "extraTrustedSiteDirectives" policy is an array
of strings, each of which is parsed as a trusted-site
directive to append to a user's own set of trusted-site
directives at launch time.
The added trusted-site directives will be considered as
part of the default set of directives by uBO.

Not much can be done beside reporting to tabless network
requests to all tabs for which the context is a match.
A short term local cache is used to avoid having to iterate
through all existing tabs for each tabless network request
just to find and report to the matching ones -- users
reporting having a lot of opened tabs at once is not so
uncommon.

This commit adds the compiled magic version number to the
compiled data itself, and consequently this allows uBO
to no longer require that any given compiled list with a
mismatched format to be detected and discarded at launch
time.
Given this change, uBO no longer needs to rely on the
deletion of cached data at launch time to ensure it
won't use no longer valid compiled lists.

When compiled data format changes, do not rely on order
of operations at launch to assume deletion of storage
occurs before attempts to access it. It's unclear this
commit will fix the reported issue, as I could not
reproduce it except when outright commenting out the code
to prevent the storage deletion from occurring.

The fix is trivial enough that I feel confident to make
it part of current RC cycle. There are many reports of
block page at launch on Chromium.
The fix is to let the platform pick it's natural suspend
state rather than force it. Once advanced settings are
read, the suspend state will for toggled only if
`suspendTabsUntilReady` is either `yes` or `no`. This
there should no longer be blocked page on Chromium at
launch when using default settings.

The old "classic" popup panel will still be used
when at least one of the following is true:
- advanced setting `uiFlavor` is set to `classic`; or
- the browser is Chromium 65 or older; or
- the browser is Firefox 67 or older
The default configuration of the new popup panel
at installation time is to show the power button,
statistics and the basic tool icons, i.e. access
to dashboard, logger, pickers.
For existing installations, the new popup panel
will be configured by respecting the existing
configuration of the classic one.
The new popup panel is currently already in use
on Firefox for Android, and the visual redesign
was made according to suggestions and feedback
from <https://github.com/brampitoyo> to be
optimal for Firefox for Android.
The new popup panel will allow closing the following

The race condition was that a content script could
query the main process to retrieve cosmetic filters
while the cosmetic filters had not been yet fully
loaded into memory. The fix ensure that an already
injected content script will re-query once the
cosmetic filters are fully loaded in memory at
browser launch time.

browser.storage.local is now used to store non-critical
local settings.
These settings are all collated under the key
`localStorage`, and vAPI.localStorage is an API to
handle access to these values stored under this key.
vAPI.localStorage.getItem() is still synchronous but
its purpose is to return internally cached values --
this minimizes code changes throughout uBO.
More specifically, this commit makes it so that
the new default UI for Firefox Preview will be
automatically selected.
A default platform-specific UI can be cancelled
by setting the advanced setting `uiFlavor` to `-`.
First draft of changes as discussed with Firefox
Preview people.
In order to allow testing/evaluating these changes,
the new advanced setting `uiFlavor` has been added.
Default to `unset`; and can currently only be set
to `fenix`.
The new setting takes effect at launch only. This
new setting is not to be mentioned in official
documentation for now.
This is ongoing work, not open to external feedback.
This commit make it so that if an *unexpected* error is
thrown when trying to load the selfie at launch, the filter

Due to browser behavior changes during development,
uBO can end up using obsolete cached compiled filter
lists or selfie.
Saving magic format values in the cache storage
itself ensure uBO will properly detect actually
obsolete compiled lists/selfie.
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/759
This commit adds code to rely less on the state of the
cache storage to decide whether filter lists should be
re-compiled or whether the selfie is currently valid
at launch time when a change in compiled/selfie format
is detected.
This is a first step, the ultimate goal is to remove
the need for resources.txt, or at least to reduce to
only hotfixes or for trivial resources targeting very
specific websites.
Most resources will become immutable, i.e. they will
be part of uBO's code base. Advantages include easier
code maintenance (jshint, syntax highlight), and to
make scriptlets more easy to code review by external
parties (for example extension store reviewers).
TODO:
- More scriptlets need to be imported before next
release.
- Need to make legacy versions of uBO use a legacy
version of resources.txt, as all the now obsolete
scriptlets will have to be removed once uBO's
next release become widespread.
- Possibly need to add code to load binary
resources so that they can be injected as
data: URI. So far it's unclear whether this is
really needed. For example, this would be needed
if a xmlhttprequest is redirected to an image
resource.

Built-in whitelist directives are now rendered differently
than user-defined whitelist directives. Also, removing a
built-in whitelist directive will only cause that directive
to be commented out, so that users do not have to remember
built-in directives should they want to bring them back.

The built-in per-site switch rule
`no-scripting: behind-the-scene false` has been removed,
it should not ever be needed since there will always be a
valid root context for main- and sub-frames.
Implement a plain string trie container class: STrieContainer.
Make use of STrieContainer where beneficial
Some filter buckets can grow quite large, and in such case
coalescing "trieable" filter classes into a single trie reduces
lookup performance and memory usage.
For instance, at time of commit, the filter bucket for the
`ad` keyword contains 919 entries[1].
Coalescing trieable filters of the same class into a single plain
string trie reduced the size of the bucket into 50 entries + two
tries which are scanned only once each whenever the bucket is
visited.

µBlock.staticNetFilteringEngine.categories.get(0).get(µBlock.urlTokenizer.tokenHashFromString('ad'))

By default `indexedDB` is used in Firefox for purpose of cache storage
backend.
This commit allows to force the use of `browser.storage.local` instead
as cache storage backend. For this to happen, set `cacheStorageAPI` to
`browser.storage.local` in advanced settings.
Additionally, should `indexedDB` not be available for whatever reason,
uBO will automatically fallback to `browser.storage.local`.
