to avoid undue repeated calls to storage deletion of
selfie assets.

The regression was preventing the compiled filter
lists from being properly loaded by uBO, thus
always causing a full parsing/compiling at
launch time.
Issue reported by @uBlock-user in team channel.
Creating cosmetic procedural exception filters was
causing `cosmetic-logger.js` scriptlet to throw at
and thus further breaking the logging of cosmetic
filters overall.
Reuse permanent instances instead. The trailing `$` is
used to denote these variables are register-like
instances, i.e. their content is valid only for the
duration of the call. (From now on I will use this
convention throughout the code base.)
Entity-based filters where not properly looked-up if
they used subdomains. Example:
- `example.*##^script` => ok
- `www.example.*##^script` => failed on `https://www.example.com/`

Messages from unprivileged ports (i.e. from content scripts)
are no longer relayed to message handlers which are to be
strictly used to execute privileged code.
The last remaining case of unprivileged messages which
should be converted into a privileged ones will be taken
care of when the following issue is fixed:

A bidi-trie can't store strings longer than 255 characters
because the string segment lengths are encoded into a single
byte. This commit ensures only strings smaller than
256 characters are stored in the bidi-tries.
Plain filters can be any length, while the bidi-trie was
assuming max length of 256. The origin of this error
is from when the bidi-trie code was originally imported
from the hntrie code as start to develop bidi-trie.
The erroneous code could cause issue when the following
conditions were met:
- Plain filter longer than 256 characters
- Free space in bidi-trie's character buffer was less
than 256 bytes
Likely a rare occurrence, but some filter lists do contains
long plain filters, for example:

The purpose is to wholly disable scriptlet injection
for a given site without having to create exceptions
for all matching scriptlet injection filters.
The following exception filter will cause scriptlet
injection to be wholly disable for `example.com`:
`example.com#@#+js()`
Or to disable scriptlet injection everywhere:
`#@#+js()`
The following form is meaningless and will be
ignored:
`example.com##+js()`

The filter option `empty` is converted to `redirect=empty`
by uBO internally; however unlike when the `redirect=`
option is used expressly, the `empty` option does not
require a resource type.
When `empty` is used, only network requests which are meant
to return a text response will be redirected to an empty
response body by uBO -- so `empty` will not work for
resources such as images, media, or other binary resources.

The color value for the icon badge is now
"attached" to the blocking profile value.
Additionally, as per feedback, `3p` rules
will be relaxing before master JavaScript
switch rules.

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.
The ability to redirect xmlhttprequest to binary
resources was lost when redirectable/injectable
resources became immutable in commit
152cea2dfe.
This commit restores the ability to redirect a
xmlhttprequest to a binary resource by making
it possible to derive a data: URI from the
content of binary resources such as images.
Addtionally a redirect to a data: URI can be
forced by prefixing the resource token with `%`.
This is a non-official feature at this point,
i.e. it could be removed at any time.

The purpose of this new option is to add the ability
to create standalone redirect rule without being forced
to create a block filter (a corresponding block filter
is always created when using the `redirect=`).
Additionally:
The syntax `*$redirect=token,...` is now supported, there
is no need to "trick" the filter parser with
`*/*$redirect=token,...` in order to create redirect rules
which are meant to match all paths.
Filters of the form `|http*://` will be normalized into
two corresponding filters `|https://` and `|http://` so as
to reduce the number of filters in the buckets of
untokenizable filters.

The following advanced setting has been added:
updateAssetBypassBrowserCache
Default to `false`. If set to `true`, uBO will ensure the
browser cache is bypassed when fetching a remote resource.
This is for the convenience of filter list maintainers who
may want to test the latest version of their lists when
fetched from their remote location.
