This patch introduces TerminalState and changes LexerTransition::mNextState to
be a Variant<State, TerminalState>. This means that SUCCESS and FAILURE no
longer need to be part of State.
Some things to note:
- This simplifies the handling of Lex()'s return value, which is nice.
- The patch splits Terminate() into TerminateSuccess() and TerminateFailure().
- |const State& aNextState| wouldn't work for the first arg to
LexerTransition's ctor due to errors in Variant construction that I didn't
understand. I had to change it to |State aNextState|.

Currently we don't implement transparency at all in BMP images except for an
odd-duck case of BMPs within ICOs.
This patch does the following.
- It implements transparency properly for 16bpp and 32bpp images via bitfield
masking. (For 32bpp images this also requires handling colors via bitfield
masking.) The patch maintains the existing BMP-within-ICO transparency
handling.
- It also reworks BitFields::Value::Set().
* It now works correctly if the run of 1s goes all the way to bit 31 (the
old code didn't set mBitWidth).
* If the mask is 0, will give an mRightShift of 0 (old code gave 32, and
right-shifting by 32 is dodgy).
* It's now easier to read.
- It renames transparent.bmp as transparent-if-within-ico.bmp. Ironically
enough this file currently uses BITFIELDS compression and is WinBMPv5 format,
which means it contains well-specified alpha data. In order to use it to test
the hacky BMP-within-ICO transparency scheme the patch changes it to be
WinBMPv3 format with RGB compression (i.e. no compression). I left the
now-excess bytes (including the bitfields) in the info header in place
because that's allowed -- thanks to the start of the pixel data being
specified by the |dataoffset| field -- they'll just be ignored.
- It tweaks the naming of the relevant gtests and some of their finer details
to work with the new way of doing things.
This fixes all four remaining failures in bmpsuite.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This patch implements proper color-scaling, instead of bit-shifting, and uses
it for 16bpp images.
It also cleans up the code relating to color masking in the process, by making
BitFields a proper class and introducing the Value class within it.
This fixes sub-optimal handling of four images in bmpsuite.
We have 52 passes and 5 known fails. Three of the passes have higher fuzziness
allowances than they should, so really there are 8 files that we need to
improve on.

|getReportsForThisProcess| differs from |getReports| in that it is limited to current process and is synchronous. When asynchronous memory reporters are added the function will no longer be able tobe synchronous. There isn't much utility in only measuring the current process, so we can remove the function and switch existing users to |getReports|.

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.
