Builtin scriptlets are no longer parsed as text-based resources,
they are imported as JS functions, and `toString()` is used to
obtain text-based representation of a scriptlet.
Scriptlet parameters are now passed as function call arguments
rather than by replacing text-based occurrences of `{{i}}`. The
arguments are always string values (see below for exception).
Support for argument as Object has been added. This opens the
door to have scriptlets using named arguments rather than
positional arguments, and hence easier to extend functionality
of existing scriptlets. Example:
example.com##+js(scriplet, { "prop": "adblock", "value": false, "log": true })
Compatibility with user-provided scriptlets has been preserved.
User-provided scriptlets can benefit some of the changes:
Use the form `function(..){..}` instead of `(function(..){..})();`
in order to received scriptlet arguments as part of function call
-- instead of using `{{i}}`.
If using the form `function(..){..}`, you can choose to receive
an Object as argument -- just be sure that your scriptlet's
parameter is valid JSON notation.
This commit fix properly handling toggling off the default
status of a list such that the list will be automatically
turned off when its status change from default to non-default.
Additionally, imported lists which become stock lists will
be properly migrated from imported lists section.

Various feedback of people trying to interact with uBO's dashboard
at browser launch, before uBO's main process is fully initialized,
causing confusion, and potential loss of data.
This new context menu entry will be available only when the
advanced setting `filterAuthorMode` is set to `true`. See:
https://github.com/gorhill/uBlock/wiki/Advanced-settings#filterauthormode
The purpose is for filter list maintainers to easily access
the source code of web pages when investigating filter issues,
without having to necessarily go through the logger.
Additionally an input field to enter URL directly has been
added to the code viewer for convenience.

Until uBO's filtering engines are properly initialized, there will
be a distinct toolbar icon to help users understand that uBO may
not be fully initialized when a webpage is loaded -- often the
cause of improper filtering of trackers/ads at browser launch.
DNR API does not support block-then-redirect concept, hence no
point in generating a DNR block rule for `redirect=` filters.
Additionally, better handle orphaned filter anchors (`||`, `|`).
This commits add the ability to open html/css/script
resources from the logger, as a formatted and syntax-
highligthed document.
The goal is to make it easier for filter list authors to
investigate filter-related issues.

Example of usage:
/img[a-z]{3,5}\.buzz/##+js(nowoif)
Use sparingly, when no other solution is practical from a maintenance point
of view -- keeping in mind that uBO has to iterate through all the regex-based
values, unlike plain hosyname or entity-based values which are mere lookups.

This new syntax does not apply to static extended filters.
This commit is a rewrite of the static filtering parser into a
tree-based data structure, for easier maintenance and better
abstraction of parsed filters.
This simplifies greatly syntax coloring of filters and also
simplify extending filter syntax.

The new option is `to=` and the value is a list of domain list with
similar syntax as `domain=` option. Entity-based syntax is supported,
and also negated hostname.
The main motivation is to give uBO's static network filtering engine
with an equivalent of DNR's `requestDomains` and `excludedRequestDomains`.
Essentially `to=` is a superset of `denyallow=`, but for now I decided
against deprecating `denyallow=`, which still does not support entity-
based syntax and for which negated domains are not allowed.
This commit also introduces the `from=` option, which is just an alias
for the `domain=` option. The logger will render network filters using
the `from=` version.

The "exceptor" feature has been rewritten, with the following
changes as a result:
- The excepted filters cease to exist when closing the logger
- It's now possible to temporary except network filters
When toggling on/off a temporary exception, filter lists are now
fully reloaded. This simplified managing temporary exceptions, and
made it easy to implement temporary exception for network filters,
but this also means there might be a perceptible delay when
adding/removing temporary exceptions. At this point I consider
this an acceptable side-effect just to bring the ability to easily
create temporary exception for network filters, while this
simplified the existing temporary exception code throughout.

These two new pseudo selectors are _action_ operators, and thus can
only be used at the end of a selector. They both take as argument
a string or regex literal.
For `:remove-class()`, when the argument matches a class name, that
class name is removed.
For `:remove-attr()`, when the argument matches an attribute name,
that attribute is removed.
These operators are meant to replace `+js(remove-attr, ...)` and
`+js(remove-class, ...)`, which from now on are candidate for
deprecation in some future.
Once the next stable release is widespread, filter authors must use
these two new operators instead of their `+js()` counterparts.

The supported syntax is exactly as per AdGuard's documentation:
- https://kb.adguard.com/en/general/how-to-create-your-own-ad-filters#extended-css-matches-attr
Though recommended, the quotes are not mandatory in uBO if
the argument does not cause the parser to fail and if there
are no ambiguities.
Additionally, improved the code to better unquote pseudo-operator
arguments, and to bring it closer to how AdGuard does it as per
documentation. When using quotes, `"` and `\` should be escaped
to preserve these characters in the unquoted version of the
argument.
Additionally, it is now possible to have `:has-text()` match the
empty string by just quoting the empty string:
...##foo:has-text("")

Some CSS4-based selectors are not supported in older browser versions
and this may cause cosmetic filtering to be wholly broken as a result.
The commit here is to isolate generic cosmetic filters from specific
ones in stylesheets such that unsupported CSS4 selectors in generic
cosmetic filters do not cause wholly breakage of cosmetic filtering
on all sites.
`uDom` is old and crusty and `dom` is meant as replacement. The
goal of `dom` is to be simpler and mainly just convenience
methods for handling the DOM with vanilla JS -- this is not a
framework.
Additionally, removed keyboard shortcuts pane which was useful
only on very old versions of Firefox.

Possibly because the Opera sidebar window is a special
case, it appears the scriptlets must be injected at a
later time.
Use a global isolated window variable to detect whether
the scriptlets have really be injected, and ultimately
inject them at main content script time when it is found
they haven't been injected at that point.
This commit make it so scriptlet injections will occur
at the earliest possible time on all platform.
This should also fix the case reported at:
- https://www.reddit.com/r/uBlockOrigin/comments/ye6abt/
Which is caused by the fact that there is no webNavigation
events being fired by the browser. In such case, the changes
here will make it so that uBO will detect that the scriptlet
were not injected and will inject them at main content script
injection time.
This commit adds the ability to inject entity-based plain CSS
filters and also a set of the most commonly used entity-based
scriptlet injection filters.
Since the scripting API is not compatible with entity patterns,
the entity-related content scripts are injected in all documents
and the entity-matching is done by the content script themselves.
Given this, entity-based content scripts are enabled only when
working in the Complete filtering mode, there won't be any
entity-based filters injected in lower modes.
Also, since there is no way to reasonably have access to the
Public Suffix List in the content scripts, the entity-matching
algorithm is an approximation, though I expect false positives
to be rare (time will tell). In the event of such false
positive, simply falling back to Optimal mode will fix the
issue.
The following issues have been fixed at the same time:
Fixed the no-filtering mode related rules having lower priority
then redirect rules, i.e. redirect rules would still be applied
despite disabling all filtering on a site.
Fixed improper detection of changes to the generic-related CSS
content script, potentially causing undue delays when for example
trying to access the popup panel while working in Complete mode.
The scripting MV3 can be quite slow when registering/updating
large content scripts, so uBOL does its best to call the API only
if really needed, but there had been a regression in the recent
builds preventing uBO from properly detecting unchanged content
script parameters.
It's possible to salvage network rule with entity syntax-based
entries in their `domain=` option if there exists at least one
entry which is not entity syntax-based.
For negated entries, these can be unconditionally removed
safely.
This adds support for `redirect=` filters. As with `removeparam=`
filters, `redirect=` filters can only be enforced when the
default filtering mode is set to Optimal or Complete, since these
filters require broad host permissions to be enforced by the DNR
engine.
`redirect-rule=` filters are not supported since there is no
corresponding DNR syntax.
Additionally, fixed the dropping of whole network filters even though
those filters are still useful despite not being completely
enforceable -- for example a filter with a single (unsupported) domain
using entity syntax in its `domain=` option should not be wholly
dropped when there are other valid domains in the list.
