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.
Consequently, AdGuard URL Tracking Protection (AUTP) has been
added to the set of available filter lists.
However, removeparam= equivalent DNR rules can only be enforced
when granting uBOL broad permissions. If broad permissions are
not granted, removeparam= equivalent DNR rules are ignored.
Exception removeparam= filters are not supported, and these are
present in AUTP and meant to unbreak some websites which are
known to break as a result of removing query parameters.
This is issue might be mitigated in the future by making the
conversion from filters to DNR rules more complicated but this
can never replace the accuracy of uBO's filtering engine being
able to fully enforce arbitrary exception removeparam= filters.
Also, it is not possible to translate regex-based removeparam=
values to DNR rules, so these are dropped at conversion time.
As with other filters to DNR rules conversion, the converter
coallesce many distinct removeparam= filters into fewer DNR
rules.
