The title of tabs in uBO is solely to have a better
presentation in the logger -- no other purpose.
This commit simplify keeping track of the titles, from
an active approach by directly querying it from tabs
whenever a change occurs, to a passive approach by
storing it when the title string become available in
some tab event handlers.

The new replacement script contains the smallest API
possible to resolve the reported case.
Please report instances where it's not sufficient to
unbreak a site, in which case I will extend the neutered
API to address these cases on an on-demand basis.

The element picker will now properly work on sites where
cosmetic filtering is disabled, but will not allow the
creation of cosmetic filters when specific cosmetic filters
are not meant to be enforced in the current page.
When specific cosmetic filters are not meant to be enforced,
the element picker will still allow the creation of network
filters, that is unless the current page is trusted, in which
case using the element picker is pointless.

This takes care of the specific case reported. There are
other edge cases which are likely not addressed though, i.e.
those involving wildcards -- those should be rather rare and
at this point I rather leave them unaddressed to not
risk regressions (as they are less trivial to address).

The surrogate script googletagmanager_gtm.js was essentially a
subset of surrogate script google-analytics_analytics.js. This
commit makes it a plain alias so that the whole GA API -- often
expected by clients of GTM -- is properly stubbed.

Findings:
One of the sublists was erroring when being fetched on
this particular CDN server (reason unknown).
uBO was not properly handling network errors when
fetching a sublist. This commit make it so that if
a sublist can't be fetched, then the error is propagated
as if it affected the whole list, in which case uBO will
use an alternative URL if any.
This advanced setting is not really needed, as the
same can be accomplished with a broad exception
filter such as `#@#+js()`.

Ever since the `redirect` code was refactored:

This advanced setting is no longer needed, as the same
can be accomplished with a plain network filter:
@@*$redirect-rule

This commit ensures FLoC is opt-in. The generic filter
`*##+js(no-floc)` in "uBlock filters -- Privacy" ensures
the feature is disabled when using default settings/lists.
Users can opt-in to FLoC by adding a generic exception
filter to their custom filters, `#@#+js(no-floc)`; or they
can opt-in only for a specific set of websites through a
more specific exception filter:
example.com,shopping.example#@#+js(no-floc)
The syntax to remove response header is a special case
of HTML filtering, whereas the response headers are
targeted, rather than the response body:
example.com##^responseheader(header-name)
Where `header-name` is the name of the header to
remove, and must always be lowercase.
The removal of response headers can only be applied to
document resources, i.e. main- or sub-frames.
Only a limited set of headers can be targeted for
removal:
location
refresh
report-to
set-cookie
This limitation is to ensure that uBO never lowers the
security profile of web pages, i.e. we wouldn't want to
remove `content-security-policy`.
Given that the header removal occurs at onHeaderReceived
time, this new ability works for all browsers.
The motivation for this new filtering ability is instance
of website using a `refresh` header to redirect a visitor
to an undesirable destination after a few seconds.

Prior to this commit, the ability to enable/disable the
uncloaking of canonical names was only available to advanced
users. This commit make it so that the setting can be
toggled from the _Settings_ pane.
The setting is enabled by default. The documentation should
be clear that the setting should not be disabled unless it
actually solves serious network issues, for example:
https://bugzilla.mozilla.org/show_bug.cgi?id=1694404
Also, as a result, the advanced setting `cnameUncloak` is no
longer available from within the advanced settings editor.
