Bring latest changes to procedural cosmetic filtering to uBOL.
Fix procedural filtering used in HTML filters.
Standardize quick hash algorithm used throughout to DJB2
(except that initialization step is skipped):

`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.
Spurious updates to registered content scripts would occur when
using some regional lists, for example DEU would cause spurious
updates to registered script `css-procedural`.
Network filters with csp= option will now be enforced.
Caveat: DNR API does not have support for exception csp= rules,
so excepted csp= filters are currently rejected at conversion 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.
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.
With the new csstree-based parser, it should now be
safe to parse `-abp-has` as declarative. There are over
a hundred such cosmetic filters in EasyList, and we want
to have these filters declaratively enforced whenever
possible in order to let the browser do the work natively
rather than rely on JS code.
The addition of those scriptlets will help uBOL to properly
filter more anti-blocker mechanisms on various site and also prevents
popups on many sites.
Also, fixed properly injecting scriptlets in embedded frames -- it
turns out I misunderstood the `allFrames` settings in the `scripting`
API.
Fixed trusted sites not being excluded from declarative
scripting.
Assign "uBOL_"-prefixed name to anonymous scripting functions
so that they can be easily found in performance profiler results
in dev tools.
Imrpove spread of chunks of filters across declarative scripting
files.
