This deprecates PYTHON_UNIT_TESTS and replaces it with PYTHON_UNITTEST_MANIFESTS.
In the build system, this means python unittests will be treated the same as all
other test suites that use manifestparser. New manifests called 'python.ini' have
been created for all test directories containing python unittests.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

XPTInterfaceDescriptor::num_additional_types can easily fit in 8 bits -- in
practice it doesn't exceed 20, and there's already a check in DoTypeDescriptor
that it doesn't exceed 255. This patch shrinks it and moves that check into
XPT_InterfaceDescriptorAddTypes() so that any overflow would be detected more
reliably.
On 64-bit platforms this reduces sizeof(XPTInterfaceDescriptor) from 40 to 32
and correspondingly reduces "xpti-working-set" by 16 KiB.
The patch also changes XPT_InterfaceDescriptorAddTypes() into a local function,
because it's defined and only used in xpt_struct.cpp.

This patch:
- Removes XPTArena's ability to support arbitrary alignments.
- Hardwires two sub-arenas into XPTArena, one with alignment of 8 and one with
alignment of 1.
- Uses the first sub-arena for most allocations and the second sub-arena for C
string allocations.
These changes reduce "xpti-working-set" by 56 KiB.
The patch also renames all the used of "malloc" in XPT identifiers with
"calloc", to make clearer that the result is always zeroed.

With careful layout we can reduce sizeof(XPTTypeDescriptor) from 4 to 3, which
also reduces sizeof(XPTParamDescriptor) from 6 to 4. This reduces
"xpti-working-set" by 16 KiB.
The union-of-structs also improves readability by making it clearer exactly
which fields are used for which types.

This requires merging XPT_DoHeaderPrologue() and XPT_DoHeader(), which is
straightforward.
This reduces "xpti-working-set" by 16 KiB on 64-bit platforms.

XPTTypeDescriptor::argnum2 is unused. Removing it reduces
sizeof(XPTTypeDescriptor) from 6 bytes to 4 bytes, which reduces the
"xpti-working-set" measurement by 80 KiB (measured on 64-bit).

Even though the .xpt files we produce never have annotations, .xpt files in the
wild might have them. This partly undoes part 3 of bug 1248534.

XPT has some functions and macros for freeing memory. However, they (a) are
only used on error paths, and (b) don't actually free memory -- they just
optionally log the "freeing" -- because piecewise freeing doesn't make sense
with arena allocation.
This patch removes all that unnecessary machinery.

RegisterBuffer() is the only place that creates an XPTState, and it also
destroys it. So the XPTState can be allocated on the stack, which voids the
need for the creation of an XPTArena.

XPT supports annotations but xpt.py doesn't generate them except for a single
empty annotation (to indicate there are no real annotations). So we can remove
almost all support for them. This also allows XPTString to be removed.

Currently XPT can both encode and decode, but encoding has been handled by
Python code since bug 643817, so the encoding support can be removed. This
results in many simplifications. Some notable changes:
- All the XPTHashTable code (including XPTDatapool::offset_map) is no longer
necessary.
- PrimitiveTest.cpp and SimpleTypeLib.cpp both don't make much sense without
encoding support, so I removed them.
- A lot of the version code was already unused, e.g. XPT_VERSION_*,
XPT_TYPELIB_VERSIONS_STRUCT, XPT_TYPELIB_VERSIONS.
XPT_MAJOR_INCOMPATIBLE_VERSION is the only thing actually used in version
checks.
- The patch also removes some code that was dead even before encoding removal,
such as XPT_ParseVersionString().

Since we no longer support binary extensions, revving an interface's IID
is not necessary for binary compatibility. However, we currently skip
relinking XPT files if a change to an interface doesn't update its IID.
This patch fixes that requirement by comparing full interfaces against
each other, so that updating an XPIDL interface without rvving its IID
works well with incremental builds.
This paves the way to remove the requirement on revving interface IIDs
when making a change to an XPIDL interface.
Its only purpose is to disable PGO. Where that was not already explicitly done,
or irrelevant (because the directory only contains python), I disabled it in
moz.build.
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.

The distinction between moz_malloc/moz_free and malloc/free is not
interesting. We are inconsistent in our use of one or the other, and
I wouldn't be surprised if we are mixing them anyways.
There are, sadly, many combinations of linkage in use throughout the tree.
The main differentiator, though, is between program/libraries related to
Gecko or not. Kind of. Some need mozglue, some don't. Some need dependent
linkage, some standalone.
Anyways, these new templates remove the need to manually define the
right dependencies against xpcomglue, nspr, mozalloc and mozglue
in most cases.
Places that build programs and were resetting MOZ_GLUE_PROGRAM_LDFLAGS
or that build libraries and were resetting MOZ_GLUE_LDFLAGS can now
just not use those Gecko-specific templates.
As a first step, this moves PYTHON_UNIT_TESTS to moz.build as a passthru
variable. In the future, we could hook it up to |mach test|.
The __init__.py files may not need to be in the list, but I don't want to
change the list here.
