The main change is that the patch copies js/public/HashTable.h to
mfbt/HashTable.h, and then changes it as follows.
- Changes `js` namespaces to `mozilla` (and removes some now-unnecessary
`mozilla::` qualifiers).
- Changes the default AllocPolicy from the SpiderMonkey-specific
`TempAllocPolicy` to the generic `MallocAllocPolicy`.
- Adds `#include "AllocPolicy.h"` (like mfbt/Vector.h).
- Changes `JS_DEBUG` use to `DEBUG`.
- Minor comment updates, as necessary.
js/public/HashTable.h is now tiny, holding just a few renamings of things from
the `mozilla` namespace into the `js` namespace to minimize churn elsewhere.
(Those renamings keep `TempAllocPolicy` as the default AllocPolicy for
js::Hash{Set,Map}.)
Also, various template specializations had to be moved from the `js` namespace
to the `mozilla` namespace to avoid compile errors.

rename : js/public/HashTable.h => mfbt/HashTable.h
Currently we have three ways of representing hash values.
- uint32_t: used in HashFunctions.h.
- PLDHashNumber: defined in PLDHashTable.{h,cpp}.
- js::HashNumber: defined in js/public/Utility.h.
Functions that create hash values with functions from HashFunctions.h use a mix
of these three types. It's a bit of a mess.
This patch introduces mozilla::HashNumber, and redefines PLDHashNumber and
js::HashNumber as synonyms. It also changes HashFunctions.h to use
mozilla::HashNumber throughout instead of uint32_t.
This leaves plenty of places that still use uint32_t that should use
mozilla::HashNumber or one of its synonyms, but I didn't want to tackle that
now.
The patch also:
- Does similar things for the constants defining the number of bits in each
hash number type.
- Moves js::HashNumber from Utility.h to HashTable.h, which is a better spot
for it. (This required changing the signature of ScrambleHashCode(); that's
ok, it'll get moved by the next patch anyway.)

Because it's more precise, and gives us more consistency.

Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:
s/mozilla::Forward/std::forward/
s/Forward</std::forward</
The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

It's an annotation that is used a lot, and should be used even more, so a
shorter name is better.
