In above related commit, uBO was modified to cache the URL of the
last clicked link, and to use this cached URL to test for the
legitimacy of the newly opened tab.
The current commit add back a test against the URL of the last
clicked link to avoid false positives when navigating from within
the newly opened tab.

The new setting, when disabled (enabled by default), allows a user
to prevent uBO from waiting for all filter lists to be loaded
before allowing network activity at launch. The setting is enabled
by default, meaning uBO waits for all filter lists to be loaded in
memory before unsuspending network activity. Some users may find
this behavior undesirable, hence the new setting.
This gives the option to potentially speed up page load at launch,
at the cost of potentially not properly filtering network requests
as per filter lists/rules.
For platforms not supporting the suspension of network activity,
the setting will merely prevent whatever mechanism exists on the
platform to mitigate improper filtering of network requests at
launch. For example, in Chromium-based browsers, unchecking the
new setting will prevent the browser from re-loading tabs for
which there was network activity while in "suspended" state at
launch.
As the trie is not immediately created, in order to speed up
launch time, the `domain=` option was stored in the filterRefs
array until it was moved to the trie.
This commit instead stores the `domain=` option into the trie
container's character buffer.
This commit will force-reload active tabs at launch for
environments not supporting suspend network request listeners,
or configured to not suspend network request listeners.
Refactored heuristics to collate set of origin-related
filter units are collated into a hostname trie, and
for better reuse of existing classes.
Generalized pre-test idea for bucket of filters, such
that in addition to origin-related filter units, there is
now a class to collate regex-based pattern-related units
into a new pre-test bucket class, FilterBucketIfRegexHits,
in order to test with a single regex test whether there is
a chance of a hit in the underlying bucket of filters.
Instances of these are rare, but at time of commit I found
this occurs with AdGuard France filter list.
Fine-tuned the "SNFE: Dump" output -- this new ability to
see the internal details of the SNFE has been really key
into finding/fixing issues during refactoring.
