uBO will now verify that at least one unprocessed network requests
at launch should have been blocked in order to warn users of
unprocessed network requests through the `!` toolbar icon badge.
For example, with default filter lists, there is nothing to block
on `wikipedia.org`, and hence in this case it's not useful to
present the user with the `!` badge.
Therefore uBO will not show the badge *only* when at least one
unprocessed network requests should have been blocked had uBO been
ready when it was fired by the browser.

The incomplete filtering status of a given tab at browser launch
will be carried over visually as a yellowish `!` badge until the
web page in the tab is force reloaded, navigated away, or closed.
The purpose is to make it obvious to end users that a web page
has not been filtered properly and to avoid issue reports
related to this.
It is expected that Firefox should never be affected by cases of
yellowish badge -- that is unless the setting "Suspend network
activity [...]" has been disabled, in which case the new behavior
will also be useful to those who disabled the setting.

Until uBO's filtering engines are properly initialized, there will
be a distinct toolbar icon to help users understand that uBO may
not be fully initialized when a webpage is loaded -- often the
cause of improper filtering of trackers/ads at browser launch.

The "exceptor" feature has been rewritten, with the following
changes as a result:
- The excepted filters cease to exist when closing the logger
- It's now possible to temporary except network filters
When toggling on/off a temporary exception, filter lists are now
fully reloaded. This simplified managing temporary exceptions, and
made it easy to implement temporary exception for network filters,
but this also means there might be a perceptible delay when
adding/removing temporary exceptions. At this point I consider
this an acceptable side-effect just to bring the ability to easily
create temporary exception for network filters, while this
simplified the existing temporary exception code throughout.

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.

The changes are enough to fulfill the related issue.
A new platform has been added in order to allow for building
a NodeJS package. From the root of the project:
./tools/make-nodejs
This will create new uBlock0.nodejs directory in the
./dist/build directory, which is a valid NodeJS package.
From the root of the package, you can try:
node test
This will instantiate a static network filtering engine,
populated by easylist and easyprivacy, which can be used
to match network requests by filling the appropriate
filtering context object.
The test.js file contains code which is typical example
of usage of the package.
Limitations: the NodeJS package can't execute the WASM
versions of the code since the WASM module requires the
use of fetch(), which is not available in NodeJS.
This is a first pass at modularizing the codebase, and
while at it a number of opportunistic small rewrites
have also been made.
This commit requires the minimum supported version for
Chromium and Firefox be raised to 61 and 60 respectively.
Disconnected ports could still happen Even when the port
was still seen as valid internally. Using a try-catch
block makes invalid port detection more reliable. This
is an occurrence I often encountered when stepping into
content script code, causing suprious error messages to
be thrown into uBO's background dev console.
Though Firefox shares a lot of WebExtensions code with Chromium,
these platforms have their own specific code paths, for various
reasons.
The reorganization here makes it clear that Chromium platform is
just one flavor of WebExtensions, and as such all Chromium-specific
code paths should no longer be automatically pulled by other
platforms where these code paths are not needed.
