Force-unsuspend when starting webRequest listener
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/759

If for some reasons the launch code throws, uBO could
find itself in permanent suspend mode, thus preventing
web pages from loading in Firefox.

Though uBO should not have exceptions thrown during
it's initialization code, this commit will ensure
uBO complete its initialization process should it
ever happen for whatever reason.

Do not bypass network listener in suspended mode
Tabless network requests were bypassing uBO's
onBeforeRequest's listener when in suspended
mode. Suspend mode occurs during the time the
filter lists are all reloaded.

Prevent spurious error messages to browser console
These spurious error messages can occur when a
extension framework API method return a
rejected Promise. In uBO the results of
browserAction methods is not used so it can be
safely discarded.

For static filter `popup` filter purpose, the URL of the
embedded frame from which the popup was launched will
be used in the matching algorithm.

Simplify client messaging code
Little-used code from vapi-client.js has been moved
to vapi-client-extra.js. Given that vapi-client.js
is injected in all web pages, this means less dead
code being injected in all pages.

Swathes of code in vapi-client.js was used only in
a few very specific cases, such as when the logger's
DOM inspector is opened or when the "Filter lists"
pane in the dashboard is opened -- and thus to avoid
that little used code to be loaded in every web page
unconditionally, it has been moved to its own
separate file, vapi-client.extra.js.

vapi-client-extra.js is loaded declaratively or
programmatically only where needed.

when an update is available; otherwise the extension will
reload only when being explicitly disabled then enabled, or

Reflect blocking mode in badge color of toolbar icon
Related feedback:
- https://www.reddit.com/r/uBlockOrigin/comments/cmh910/

Additionally, the `3p` rule has been made distinct from
`3p-script`/`3p-frame` for the purpose of
"Relax blocking mode" command.

The badge color will hint at the current blocking mode.
There are four colors for the four following blocking
modes:
- JavaScript wholly disabled
- All 3rd parties blocked
- 3rd-party scripts and frames blocked
- None of the above

The default badge color will be used when JavaScript is not
wholly disabled and when there are no rules for `3p`,
`3p-script` or `3p-frame`.

A new advanced setting has been added to let the user choose
the badge colors for the various blocking modes,
`blockingProfileColors`. The value *must* be a sequence of
4 valid CSS color values that match 6 hexadecimal digits
prefixed with`#` -- anything else will be ignored.

Add ability to suspend network request handler at will
This works only for platforms supporting the return of
Promise by network listeners, i.e. only Firefox at this
point.

When filter lists are reloaded[1], there is a small
time window in which some network requests which should
have normally been blocked are not being blocked
because the static network filtering engine may not
have yet loaded all the filters in memory

This is now addressed by suspending the network request
handler when filter lists are reloaded -- again, this
works only on supported platforms.

[1] Examples: when a filter list update session
    completes; when user filters change, when
    adding/removing filter lists.

Add keyboard support for toggling down blocking profile
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/371

By default, no specific keyboard shortcut is predefined,
this will have to be assigned by the user. The command
name in English is "Toggle blocking profile".

The default behavior is to toggle down according to one
of the following scenarios.

a) If script execution is disabled through the no-scripting
switch, the no-scripting switch will be locally toggled
so as to allow script execution. The page will be
automatically reloaded.

b) If script execution is not blocked but the 3rd-party
script and/or frame cells are blocked, local no-op rules
will be set so as to no longer block 3rd-party scripts
and/or frames. The page will be automatically reloaded.

Given this, it may take more than one toggle down command
to reach the lowest blocking profile, which is one where
JavaScript execution is not blocked and 3rd-party scripts
and frames resources block rules, if any, are bypassed
with local no-op rules.

TODO: At this point, I haven't yet decided whether
toggling from the lowest profile should restore the
original highest blocking profile.

Handle possible exceptions in vAPI.messaging.broadcast()
I had exceptions thrown by that code once in a while,
about the `port` object not being connected; possibly
occurs only when using dev tools with breakpoints
in uBO's code. Even if this can be reproduced randomly
only when debugging uBO, it costs nothing to add code
in there to handle exceptions.

Web accessible secrets can be used for at most one second

Related Chromium issue (I can't access it):
- https://bugs.chromium.org/p/chromium/issues/detail?id=957866

Findings so far: affects browsers based on Chromium 74.
I could not reproduce the issue with either Chromium 73 or
Google Chrome 75.

This commit is a mitigation: to prevent sites from using
uBO's internal WAR secret for tracking purpose. A secret
can be used for at most one second, after which a new secret
is generated.

secret-gated web accessible resources is:

Make use of `X-DNS-Prefetch-Control` in Chromium-based browsers
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/548

The fix applies only to Chromium-based browsers -- a
`X-DNS-Prefetch-Control` header[1] will be unconditionally
injected when uBO's "Disable pre-fetching" setting is
enabled (it is by default).

This is a mitigation, this does not completely fix the issue
of the setting "Disable pre-fetching" being disregarded on
Chromium-based browsers when sites use
`preconnect`/`preload`.

Allow use of browser.storage.local as cache storage backend in Firefox
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/409

By default `indexedDB` is used in Firefox for purpose of cache storage
backend.

This commit allows to force the use of `browser.storage.local` instead
as cache storage backend. For this to happen, set `cacheStorageAPI` to
`browser.storage.local` in advanced settings.

Additionally, should `indexedDB` not be available for whatever reason,
uBO will automatically fallback to `browser.storage.local`.
