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.

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.
We want to be able to enter the Realm we were in when the callback was created
before calling it, but if the callback stores a cross-compartment wrapper we
don't really have a good way to find that Realm. So we store it explicitly by
storing a global when the callback is created.
The changes to the constructor signatures to use JSObject* instead of
JS::Handle<JSObject*> are so we can avoid having to root the global for these
calls. These changes make two of the constructors ambiguous when nullptr is
being passed for the first arg; this patch adds casts to disambiguate.
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.

Summary:
This macro simplifies code which allows performing an operation on or
extracting information from a particular nsXPTType's native representation.
It is also used in part 2 to implement xpc::DestructValue.

Summary:
This patch ports xptcodegen.py over to the new perfecthash.py system, removing
some special-case code generators, and taking advantage of the easier-to-use
interface.
In addition, the code was changed to take advantage of the endianness
information from Part 2, allowing us to avoid having to perform endianness swaps
at runtime when hashing nsIDs.

Bug #: 1479484
Differential Revision: https://phabricator.services.mozilla.com/D2618
Summary:
This is a streamlined version of perfecthash.py from xpcom/reflect/xptinfo.
There are a few major changes here:
Instead of providing '(key, value)' pairs to the constructor, callers provide a
list of 'entries'. An optional 'key' parameter allows overriding the function
used to get an entry's key. The default behaviour is as before, destructuring a
(key, value) tuple.
Keys can now be anything which supports the 'memoryview' protocol with 1-byte
elements, rather than being forced to be a 'bytearray'. This allows passing in
types such as bytestrings.
A new 'cxx_codegen' method is now exposed which generates a series of
fully-contained C++ declarations to perform entry lookups. It is possible to
override many parts of this codegen to make it the best fit for your component.
PerfectHash remembers the 'key' function, meaning lookup methods automatically
verify a valid key was passed in, and return 'None' otherwise.

Summary:
The plan is to also expose perfecthash.py from this module on the python path.
This also allows us to stop using explicit module loading to load make_dafsa.py.
make_dafsa.py was moved into tools/ to avoid any extra python files from
accidentally ending up on the python path.

This makes it possible to use different lists for tracking protection
and for the features that rely on tracking annotations.
