The source filename should only be used as the destination filename if
we don't have a target_basename entry for the file. For most cases
there is no difference, but in browser/components/places/jar.mn, the
same source file (bookmarkProperties.xul) is used to two different
destination files (bookmarkProperties.xul and bookmarkProperties2.xul).

The forces on the system are such that I really need to be able to
FORCE a few RecursiveMake targets in order to make Android and Gradle
use GENERATED_FILES and LOCALIZED_GENERATED_FILES. Over time, I hope
to avoid FORCE, but that time is not now.

Historically we built all our binaries in directories in the objdir, then
symlinked them into dist/bin. Some binaries needed to be copied instead
so that certain relative path lookups work properly, so we resorted to
sprinkling `NSDISTMODE=copy` around Makefiles.
This change makes it so we build PROGRAMs (not any other sort of targets)
directly in dist/bin instead. We could do the same for our other targets
with a little more work.
There were several places in the tree that were copying built binaries to
some other place and needed fixup to match the new location of binaries.
On Windows pdb files are left in the objdir where the program was
originally linked. symbolstore.py needs to locate the pdb file both to
determine whether it should dump symbols for a binary and also to copy
the pdb file into the symbol package. We fix this by simply looking for
the pdb file in the current working directory if it isn't present next
to the binary, which matches how we invoke symbolstore.py.

There a few pieces needed here to properly handle KeyboardInterrupts.
1. All in-progress work needs to abort. Ideally the underlying linters will be
able to catch KeyboardInterrupt, and return partial results (like the flake8
linter does). Linters may alternatively allow the KeyboardInterrupt to
propagate up. Mozlint will catch and handle this appropriately, though any
results found will be lost. The only change to this behaviour was fixing a bug
in the flake8 linter.
2. Any unstarted jobs need to be canceled. In concurrent.futures, there are two
different queues. First, jobs are placed on the work queue, which is just a list
maintained by the parent process. As workers become available, jobs are moved
off the work queue, and onto the call queue (which is a multiprocessing.Queue).
Jobs that live on the work queue can be canceled with 'future.cancel()', whereas
jobs that live on the call queue cannot. The number of extra jobs that are stored
on the call queue is determined by this variable:
https://hg.mozilla.org/mozilla-central/file/deb7714a7bcd/third_party/python/futures/concurrent/futures/process.py#l86
In this patch, the parent process' sigint handler (which will be called on Ctrl-C)
is responsible for canceling all the jobs on the work queue. For the jobs on the
call queue, the best we can do is set a global variable that tells workers to
abort early.
3. Idle workers should exit gracefully. When there are no more jobs left, workers
will block on the call queue (either waiting for more jobs, or waiting for the
executor to send the shutdown signal). If a KeyboardInterrupt is received while a
worker is blocking, it isn't possible to intercept that anywhere (due to quirks
of how concurrent.futures is implemented). The InterruptableQueue class was
created to solve this problem. It will return None instead of propagating
KeyboardInterrupt. A None value will wake the worker up and tell it to gracefully
shutdown. This way, we avoid cryptic tracebacks in the output.
With all of these various pieces solved, pressing Ctrl-C appears to always exit
gracefully, sometimes even printing partial results.

This commit doesn't change any behaviour, just attempts to make this a little
more readable. The workers will call '_collect_results' for each WorkItem they
process (either because it is finished or because it was canceled).
This also differentiates between setup failures and run failures.

This cleans up a few things, including simplifying the look of
backend.mk by keeping the relsrcdir in MERGE_RELATIVE_FILE similar to
the source path in the tree. Before, the locales/ floated around,
which is hard to understand but doesn't matter, since it's stripped by
MERGE_RELATIVE_FILE.
This also tests both relative and topsrcdir-absolute paths.

`mach clobber python` currently purges Python files with known
extensions globally.
The python/ and third_party/python/ directories may also contain random
ignored/untracked files. Let's purge those as well.
Note: if someone has untracked but not ignored files, this will delete
them. This is possibly unwanted. But people shouldn't have untracked
but not ignored files sitting around in VCS. We don't run this command
by default, so I think it is safe to be aggressive in our purging of
these untracked files.

`mach clobber python` is supposed to remove autogenerated Python files.
Let's add .pyd files (compiled C extensions on Windows) to the list
for good measure.
