There is no point for such list since it's not possible
to get breakage measurements from using such list and
thus impossible to evaluate.
At the same time, "uBlock filters --- Annoyances" has
been moved to the "Annoyances" section.
Tokens which are as long or longer than the max token
length possible do not need to have the prefix part
evaluated against special regex characters. This will
help increase the likelihood of extracting a valid
token from regex-based filters.
Actual case found in EasyPrivacy:
/^https?:\/\/eulerian..*\/[a-z0-9]{2,12}\.js/$script
Before this commit, uBO was not able to extract a
valid token, while now uBO is able to extract `eulerian`
as a valid token (consequently the regex-based filter
will now be evaluated only when the token `euleria` is
found in a URL).
This is related to the list of domains/subdomains in
the dynamic filtering pane of the popup panel.

Clicking on the empty space of a row will toggle
the visibility of the subdomains.
Additionally, the root context will always be visible
regardless of the expand/collspase state, along with
a visual indicator that a specific domain or subdomain
is the actual root context. (the root context is the
hostname in which local rules are created).

uBO was testing for regex-like plain patterns after
prepending `@@` in the case of exception filters, thus
preventing proper detection of regex-like plain
patterns. The filtering engine was not affected, only
the proper rendering of the filter in the logger was
affected.
Advanced setting `cnameAliasList` has been removed.
New advanced settings:
cnameUncloak:
Boolean
Default value:
true
Description:
Whether to CNAME-uncloak hostnames.
cnameIgnoreExceptions:
Boolean
Default value:
true
Description:
Whether to bypass the uncloaking of network requests
which were excepted by filters/rules. This is
necessary so as to avoid undue breakage by having
exception filters being rendered useless as a result
of CNAME-uncloaking.
For example, `google-analytics.com` uncloaks to
`www-google-analytics.l.google.com` and both hostnames
appear in Peter Lowe's list, which means exception
filters for `google-analytics.com` (to fix site
breakage) would be rendered useless as the uncloaking
would cause the network request to be ultimately
blocked.

The change in this commit make it so that it's no
longer required to have an exception filter for
`google-analytics.com/analytics.js` for the page to
render properly.

This adds two new advanced settings:
- cnameIgnoreRootDocument
- Default to `true`
- Tells uBO to skip CNAME-lookup for root document.
- cnameReplayFullURL
- Default to `false`
- Tells uBO whether to replay the whole URL or just
the origin part of it.
Replaying only the origin part is meant to lower
undue breakage and improve performance by avoiding
repeating the pattern-matching of the whole URL --
which pattern-matching was most likely already
accomplished with the original request.
This commit is meant to explore enabling CNAME-lookup
by default for the next stable release while:
- Eliminating a development burden by removing the
need to create a new filtering syntax to deal with
undesirable CNAME-cloaked hostnames
- Eliminating a filter list maintainer burden by
removing the need to find/deal with all base
domains which engage in undesirable CNAME-cloaked
hostnames
The hope is that the approach implemented in this
commit should require at most a few unbreak rules
with no further need for special filtering syntax
or filter list maintance efforts.

Each token requires two slots in the token indices
array. This commit fixes uBO breaking when dealing
with very long URLs with lot of distinct tokens in
them.
This fixes the ability to block when a hostname
had to be cname-resolved the first time it was
encountered. The result being cached allowed
the subsequent requests to be correctly blockable.
