This is the main patch for the bug. It aims to change the grapheme cluster
break's `Next()` API by implementing SegmentIteratorUtf16 interface, and adapt
the callers. It shouldn't change the behavior.
While rewriting the caller, one caveat worth mentioning is the loop termination
condition. If the old code relies on `!AtEnd()` as the loop termination
condition, and it advances the iterator at the end of the loop, it meant
to *skip* its logic when the break position is at the end of the string. For
example, see the `mozTXTToHTMLConv::NumberOfMatches`.
This patch also hooks grapheme cluster break iterator into
Segmenter::TryCreate() interface.
Existing test coverage for the file changed:

- layout/reftests/forms/input/file/dynamic-max-width.html

Using hyphenation patterns from https://github.com/santhoshtr/hyphenation.
The tests here are implemented as Mozilla reftests rather than added to WPT because I don't think
we can reasonably have such tests in WPT. The specific set of languages for which the UA supports
auto-hyphenation is not a normative requirement, and nor is the particular dictionary or algorithm
that will be used for any specific language. As such, the exact results are not defined by the
spec. (They may also change over time, if the hyphenation rules we use are updated, in which case
the tests will have to change accordingly.)

Awkwardly, this relies upon a different ICU4C NumberFormat API than
the existing intl::NumberFormat implementation, so it seems best to
have this live in a separate class.

Implements https://github.com/whatwg/html/issues/6962 . Improves performance
when <meta charset> occurs in head but after the first kilobyte and aligns
behavior better with WebKit and Blink.
The main change is to avoid reloads when meta appears within head but
after the first kilobyte. Prior to this change, Gecko reloaded in that
case (in compliance with the spec!) even though WebKit and Blink did not.
Differences from WebKit and Blink:
* WebKit and Blink honor <meta charset> in <noscript>. This implementation
does not.
* WebKit and Blink look for meta as if the tree builder was unaware of
foreign content. This implementation is foreign content-aware. This
makes a difference for CDATA sections that contain a > before the meta
as well as style and script elements within foreign content. This could
happen if the CDATA section that has mysteriously been introduced around
a what looks like a meta tag also contains another prior tag-looking
run of text.
* This implementation processes rel=preload and speculative loads that are
seen before <meta charset> has been seen. WebKit and Blink instead first
look for the meta and rewind before starting speculative parsing.
* Unlike WebKit, if there is neither an honored meta nor syntax resembling
an XML declaration, detection from content takes place (as in Blink).
* Unlike Blink, if there is neither an honored meta nor syntax resembling
an XML declaration, the detection from content is not dependent of network
buffer boundaries.
* Unlike Blink, detection from content can trigger a reload at the end of
the stream if the guess made at that point differs from the first guess.
(See below for the definition of the input to the first guess.)
Differences from the old spec and Gecko previously:
* Meta inside script and RCDATA elements is no longer honored.
* Late meta is now ignored and no longer triggers a reload.
* Later meta counts as early enough meta: In addition to the previous
meta within the first 1024 bytes, now a meta that started within the first
1024 bytes counts as early enough. Additionally, if by then there hasn't
been a template start tag and head hasn't ended, meta occurring before the
earlier of the end of the head or a template start tag counts as early
enough.
* Meta now counts as not-late even if the encoding label has numeric
character reference escapes.
* Syntax resembling an XML declaration longer than a kilobyte is honored if
there is no honored meta.
* If there is neither an honored meta nor syntax resembling an XML declaration,
the initial chardetng scan is potentially longer than before: the first 1024
bytes, the token spanning the 1024-byte boundary if there is such a token,
and, if by then head hasn't ended and there hasn't been a template start tag
until the end of the template start tag or the end of the token that causes
head to end, ever comes first. However, if the token implying the end of the
head is a text token, bytes only to the end of the previous non-text token is
considered. (This definition avoids depending on network buffer boundaries.)
* XML View Source now uses the code for syntax resembling an XML declaration
instead of expat for extracting the internal encoding label.
Reftest are added as both WPT and Gecko reftests in order to test both http:
and file: URL scenarios. The Gecko tests retain the WPT <link> tags in order
to use the exact same bytes.
An encoding declaration has been added to a number of old tests that didn't
intend to test the new speculation behavior especially in the context of
https://bugzilla.mozilla.org/show_bug.cgi?id=1727750 .

This patch contains changes to moz_task to improve it's support for
async execution on multiple threads. Unlike the previous executor
implementation, this new implementation reduces the amount of unsafe
code substantially by depending on the async-task crate
(https://crates.io/crates/async-task) for the core task implementation.
This adds a few additional features:
* Both local (no Send bound) and non-local (with Send bound) execution support,
* Support for spawning on arbitrary nsIEventTargets or the background task pool,
* Returned Task objects from runnables which may be .await-ed on or detach()-ed,
* Support for spawning with the NS_DISPATCH_EVENT_MAY_BLOCK flag set,
* Automatic use of NS_DISPATCH_AT_END when required,
* Support for specifying the runnable priority for runnables.
There are also some correctness improvements, and exposed a better API
for dispatching normal runnable functions to background threads.
After these changes the TaskRunnable API should no longer be necessary.
It is re-implemented on top of the executor and kept in-place to avoid
rewriting all consumers.

useful abstraction over the DateTimeFormat interface when used
specifically with Gecko. It applies the OS preferences and provides some

-Wshadow warnings are not enabled globally, so these -Wno-shadow suppressions have no effect. I had intended to enable -Wshadow globally along with these suppressions in some directories (in bug 1272513), but that was blocked by other issues.
There are too many -Wshadow warnings (now over 2000) to realistically fix them all. We should remove all these unnecessary -Wno-shadow flags cluttering many moz.build files.
