Bug 1723674 added a new nsID::GenerateUUID() static factory function to generate UUIDs without the overhead of querying and instantiating an nsIUUIDGenerator object. nsContentUtils::GenerateUUID() is a utility function that amortizes that overhead by holding an nsIUUIDGenerator singleton. That's no longer necessary because code that calls nsContentUtils::GenerateUUID() can now just call nsID::GenerateUUID(). No nsIUUDGenerator is needed.

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 .

-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.

NOTE! In cases where there is no HTTP-layer encoding declaration, and CSS
parsing inherits the encoding from the HTML document, for preloads, this
changes the inherited encoding from windows-1252 to UTF-8 in order to
make the speculative encoding correct in the common `<meta charset=utf-8>`
case.

Automatically generated path that adds flag `REQUIRES_UNIFIED_BUILD = True` to `moz.build`
when the module governed by the build config file is not buildable outside on the unified environment.
This needs to be done in order to have a hybrid build system that adds the possibility of combing
unified build components with ones that are built outside of the unified eco system.

This change ensures that the tokenizer sets the doctype name to null
when the doctype name is missing in the input source.
Otherwise, without this change, the doctype name is set to the empty
string — which doesn’t conform to the requirements in the HTML spec, and
which causes us to fail 9 tests in the html5lib-tests suite.

This change ensures that for all cases with spec requirements in the
form “clear the stack back to a foo context” — which involves checking
for elements with particular names — we only look for elements in the
HTML namespace, rather than additionally looking for elements which
aren’t in the HTML namespace but that also have those particular names.
Otherwise, without this change, we aren’t in conformance with the spec
requirements, and we fail several cases in the html5lib-tests suite.

This change brings the tokenizer’s handling of U+0000 NUL characters in
the DATA state and the CDATA section state into conformance with the
requirements in the HTML spec — for the case where only tokenization is
being performed, without tree construction; that is, the case where the
tokenizer() method is called, rather than parse() or parseFragment().
Specifically, the tokenization steps defined in the spec require that
when a U+0000 NUL is consumed in the DATA state or in the CDATA section
state, the parser must then emit a U+0000 NUL. But when performing tree
construction, the spec requires that when a U+0000 NUL is consumed, the
parser must instead emit a U+FFFD REPLACEMENT CHARACTER.
Without this change, the parser always emits a U+FFFD REPLACEMENT
CHARACTER — even when only tokenization is being performed. That causes
us to fail a number of tests in html5lib-tests suite.

When the parser encounters a `</template>` end tag and there are other
open elements, the HTML spec requires the parser to “generate all
implied end tags thoroughly”, which unlike “generate implied end tags”
also includes generating implied end tags for table-parts elements
(caption, colgroup, tbody, thead, tfoot, td, th, and tr).

Doing `errUnclosedElements(eltPos, "template")` for EOF in the “in
template” state results in the error message “End tag `template` seen, but
there were open elements”, which is all wrong because the actual problem is
that though a `template` end tag was expected, EOF was reached without a
`template` end tag being seen.
So let’s instead when we reach this just report the list of open elements.
