Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.

This introduces the machinery needed to generate crash annotations from a YAML
file. The relevant C++ functions are updated to take a typed enum. JavaScript
calls are unaffected but they will throw if the string argument does not
correspond to one of the known entries in the C++ enum. The existing whitelists
and blacklists of annotations are also generated from the YAML file and all
duplicate code related to them has been consolidated. Once written out to the
.extra file the annotations are converted in string form and are no different
than the existing ones.
All existing annotations have been included in the list (and some obsolete ones
have been removed) and all call sites have been updated including tests where
appropriate.

Loading SpecialPowers into frame scripts has side-effects, detailed in part 1,
which are undesirable. The main side-effect that I'm trying to get rid of here
is the force-enabling of permissive COWs in frame script scopes, which is
blocking changes that I need to make elsewhere. But both that and the scope
pollution it causes are likely to allow code to work when running in
automation which fails in real world usage.
This patch changes our special powers frame scripts to load specialpowers.js
and specialpowersAPI.js as JSMs, which run in their own global, but define
most of the same properties on our frame script globals.
Most other callers still load those scripts via <script> tags or the subscript
loader, and should ideally migrated in a follow-up. But even so, this patch
still gives us a cleaner separation of the frame script and non-frame-script
loading code.

This alters nsILoadURIDelegate.loadURI() to return a Promise rather than spinning the event loop to synchronously return a boolean, and alters nsDocShell::InternalLoad to allow for those changes by re-calling itself if necessary based on the resolution of the promise.
This introduces the machinery needed to generate crash annotations from a YAML
file. The relevant functions are updated to take a typed enum (in C++) and an
integer constant (in JavaScript). A JavaScript wrapper around the crash
reporter service is provided to hold the constants. The existing whitelists
and blacklists of annotations are also generated from the YAML file and the
existing duplicate code has been consolidated. Once written out to the .extra
file the annotations are converted in string form and are no different than
the existing ones.
All existing annotations have been included (and some obsolete ones removed)
and all call sites have been updated including tests.

DocShells are associated with outer DOM Windows, rather than Documents, so
having the getter on the document is a bit odd to begin with. But it's also
considerably less convenient, since most of the times when we want a docShell
from JS, we're dealing most directly with a window, and have to detour through
the document to get it.
