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.

The Win32 has non-malloc based heap allocation functions. They are not
widely used in the Gecko code base, but there are a few places that do
use them. They could be replaced with uses of malloc/free/realloc or
new/delete, but there is now an entirely separate problem that
requires wrapping those functions: the Rust static libraries are using
those functions to allocate memory.
Since bug 1253512 landed, it's possible for DeadBlocks to lack an allocation
stack.

Since the introduction of the STL wrappers, they have included
mozalloc.h, and multiple times, we've hit header reentrancy problems,
and worked around them as best as we could.
Taking a step back, all mozalloc.h does is:
- declare moz_* allocator functions.
- define inline implementations of various operator new/delete variants.
The first only requires the functions to be declared before they are used,
so mozalloc.h only needs to be included before anything that would use
those functions.
The second doesn't actually require a specific order, as long as the
declaration for those functions comes before their use, and they are
either declared in <new> or implicitly by the C++ compiler.
So all in all, it doesn't matter that mozalloc.h is included before the
wrapped STL headers. What matters is that it's included when STL headers
are included. So arrange things such that mozalloc.h is included after
the first wrapped STL header is fully preprocessed (and all its includes
have been included).
It's an annotation that is used a lot, and should be used even more, so a
shorter name is better.

Bug 691003 made the minimum allocation size word sized for Linux and OS X, we
now need to do a similar change on Windows as well. For Windows the requirement
is 8-bytes on 32-bit and 16-bytes on 64-bit.
Due to the change in part 1, DMD now prints an entry for every live block,
which increases the output file size significantly in the default case. However,
a lot of those entries are identical and so can be aggregated via the existing
"num" property.
This patch does that, reducing output size by more than half.

DMD currently uses a very hacky form of "sampling" by default to avoid
recording stack traces for all blocks. This makes DMD run faster than when it
records all stack traces.
This patch changes the sampling method used; in fact, it avoids "sampling" at
all. The existence of all heap blocks is now recorded exactly, but by default
we only record an allocation stack for each heap block if a Bernoulli trial
succeeds. This choice works well because getting the stack trace is ~100x
slower than recording the block's existence.
Overall, this approach is simpler and it also gives better output -- the choice
of which blocks to record allocation stacks for is mathematically sound, no
stack trace gets blamed for allocations it didn't do, and block counts and
sizes are now always exact.
Other specific things changed.
- All notion of sampling is removed from the various data structures.
- The --sample-below option is removed in favour of --stacks={partial,full}.
- The format of the JSON output file has changed.
- The names of various test files have changed to reflect concept changes.

This reduces memory usage by up to 3 MiB per process.

MOZ_DEBUG_DEFINES are essentially defines used everywhere. So treat them as
feeding the initial value for DEFINES in each moz.build sandbox. This allows
the kind overrides that was done in the past by resetting MOZ_DEBUG_DEFINES
in Makefiles.
DONTBUILD because it only changes comments.
This will hopefully prevent confusion like that in bug 1215903.
