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 new entry is an array of strings, each representing a
distinct line, and all entries are used to populate the
"My filters" pane.
This offers an more straightforward way for administrators
to specify a list of custom filters to use for all
installations.
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.

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.

uBO will not discard secondary requests fired before a root
frame is committed, by ensuring that if newly uncommitted
root frames are of the same origin as previous one(s), the
uncommited journal slot pointer is not updated.

Patternless `queryprune` ar enow preserved as being
pattern-less while still attempting to extract a token
from the `queryprune` value. This allows to report the
filter in the logger same as its original form.
The following regex are not rejected as invalid when
using built-in regex objects:
/abc]/
/a7,18}/
/a{7,18/
However, as per documentation, they are not supposed to
be valid, as `{` and `}` are special characters and as
such should be escaped:
/abc\]/
/a7,18\}/
/a\{7,18/
With this commit, the regexes will additionally be
validated using the regex analyzer library in the editor
to ensure strict regex syntax compliance so as to avoid
what are likely mistakes in regex crafting by authors.
This commit fixes mouse double-click-and-drag operations,
which was broken due to the implementation of a custom
word selection in the filter list editor/viewer.
Regex-based static network filters are those most likely to
cause performance degradation, and as such the best guard
against undue performance degradation caused by regex-based
filters is the ability to extract valid and good tokens
from regex patterns.
This commit introduces a complete regex parser so that the
static network filtering engine can now safely extract
tokens regardless of the complexity of the regex pattern.
The regex parser is a library imported from:
https://github.com/foo123/RegexAnalyzer
The syntax highlighter adds an underline to regex-based
filters as a visual aid to filter authors so as to avoid
mistakenly creating regex-based filters. This commit
further colors the underline as a warning when a regex-based
filter is found to be untokenizable.
Filter list authors are invited to spot these untokenizable
regex-based filters in their lists to verify that no
mistake were made for those filters, causing them to be
untokenizabke. For example, what appears to be a mistake:
/^https?:\/\/.*\/sw.js?.[a-zA-Z0-9%]{50,}/
Though the mistake is minor, the regex-based filter above
is untokenizable as a result, and become tokenizable when
the `.` is properly escaped:
/^https?:\/\/.*\/sw\.js?.[a-zA-Z0-9%]{50,}/
Filter list authors can use this search expression in the
asset viewer to find instances of regex-based filters:
/^(@@)?\/[^\n]+\/(\$|$)/
This should improve usability of uBO's hard-mode
and "relax blocking mode" operations. This is the
new default behavior.
The previous behavior of forcing a reload of the
page can be re-enabled by simply setting the `3p`
bit of the advanced setting `blockingProfiles`
to 1.

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.

The recognized resources are:
- abp-resource:blank-mp3
- abp-resource:blank-js
ABP's tokens are excluded from auto-complete so as to not
get in the way of uBO's filter list maintainers.
