Usage of space in network filter patterns will now be
strictly interpreted as the filter being a hosts file
entry.
Usage of space in any other scenario will cause the
pattern of the network filter to be rejected as
erroneous.
The pseudo user styles code served only browsers based
on Chromium 65 and earlier -- Chromium 66 supports
native user styles and was first released more than two
years ago.
In Chromium-based browsers, the pseudo user styles code
is being unconditionally injected in every page/frame
just in case the browser is version 65 or earlier.
Removing pseudo user styles reduce uBO's main content
script in Chromium-based browsers by more than 20K.

No need to mind rejected promise after all,
vAPI.tabs.executeScript() is designed to
not fail -- I had forgotten about this.

As a result of earlier redesign, the magnifier ended
up being too small. The size of the magnifier will now
be dependent on the default font size instead of the
parent font size.

It's not clear the code here will fix the reported
issue, but I did identify that the subframe
dictionary of a very long-lived web page can
theoretically grow unbound.
Regression from:

The issue was causing the element picker to being
unable to select elements with no valid `srcset`
property.
Test case -- trying to select one of the embedded
frames in the following page would fail:
- http://raymondhill.net/ublock/tiles1.html
Lines in AdGuard filter lists have trailing `\r`
characters, and these caused the redirect engine
compile code to reject as invalid the redirect
token.
This is trivially fixed by trimming the raw option
strings before parsing it in the redirect engine.

CodeMirror's code folding reference:
- https://codemirror.net/doc/manual.html#addon_foldcode
This commit adds support for code-folding to the filter
list editor/viewer.
The following blocks of code are foldable by clicking the
corresponding marker in the gutter:
- !#if/#endif blocks
- !#include blocks
Addtionally, the following changes:
- The `!#include` line is now preserved when importing a
sublist
- The `!#if` directives will be syntax-colored according
to whether they evaluate to true or false on the current
platform
- Double-clicking on a foldable line in the gutter will
select the content of the foldable block
- Minor visual improvement to matching brackets
Auto-completion will work only for uBO's own
tokens, compatibility-related tokens[1] will not be
taken into account for auto-completion.
The reason is to not have the compatibility-related
tokens get in the way of auto-completion in order
to not inconvenience uBO's filter list maintainers.
[1] `adguard_ext_chromium`, `adguard_ext_firefox`,
etc.

Invalid values for `!#if ...` will be highlighted as errors.
Auto completion is now supported for both the directives
themselves and the valid values for `!#if ...`.
For examples, when pressing ctrl-space:
- `!#e` will auto-complete to `!#endif`
- `!#i` will offer to choose between `!#if ` or `!#include `
- `!#if fir` will auto-complete to `!#if env_firefox`
Additionally, support for some of AdGuard preparsing
directives, i.e. `!#if adguard` is now a valid and will be
honoured -- it always evaluate to `false` in uBO.
In case of invalid `Expires` value -- i.e. `NaN` -- do
not use `1` as default value, just let uBO pick the
value according to the global default (which is `5` as
of commit time).

Specifically;
- `beacon`, `ping`, and `websocket` cannot be redirected;
- it's ok to not specify a type when redirecting to `empty`
resource;
- `csp=` option can't be mixed with other types, redirec
directives, and more `csp=` options.

Additionally, match unconditionally against `srcset` attribute
when trying to find matching elements in the page. For example,
sometimes an img element may set both `src` and `srcset`
properties, they should not be deemed mutually exclusive.

Unicode characters inside hostname part of a filter will
be converted to punycode.
Unicode characters anywhere else in the pattern will be
percent-encoded.
Unicode characters which cannot be encoded will cause a
filter to be invalid.
This fix the case of the following filter:
trk*.vidible.tv
Not matching:
https://trk.vidible.tv/trk/.vidible.tv
The wildcard is supposed to match any number of
characters, including zero characters. The issue
is that the code was not matching zero characters.
This is due to an incorrect comparison in
BidiTrieContainer.indexOf(), causing the code to
bail out before testing for the zero character
condition.
The regression broke filters of the form:
||trk*.vidible.tv^
The new parser will eventually interpret differently
wildcard characters when they are used in a manner
meant to represent only hostname-valid characters,
but this will come in a future version -- for now
the default meaning must be preserved until the
static network filtering engine is modified to
enforce the new interpretation.

For unknown reasons at this point, it appears some users
end up with a truncated version of EasyList, leading to
improper blocking in uBO.
This commit adds a heuristic to discard a downloaded list
when its new size is more than 25% smaller than the
currently cached version.
