at interpreter startup before importing any non-builtin modules.
Should fix #9589.

exposed in Python.h.  This function is similar to POSIX
gettimeofday(struct timeval *tp), but available on platforms without
gettimeofday().

configure to append to Python's default values for those variables, and
similarly allow users to set $XXFLAGS on the make command line to append to the
values set by configure.

In the makefile, this renames the variables that used to be $XXFLAGS to
$PY_XXFLAGS, and renames the old $PY_CFLAGS to $PY_CORE_CFLAGS.  To compensate,
sysconfig now aliases $XXFLAGS=$PY_XXFLAGS so that scripts using it keep
working.  I see that as the right interface, not a backward-compatibility hack,
since these are logically the $XXFLAGS variables; we just use a different name
in the makefile to deal with make's semantics.

Revert r82259; still no good way to override instead of replace OPT, but changing order alters pydebug optimization flags.

from the fact that OPT contains -Wall be default. This is annoying when
compilers like clang have thorough debugging information about things that
Python does extensively (e.g. -Wunused-value for unused return values caused by
a macro use).

http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data
race detector that runs on top of valgrind. With this patch, the binaries at
http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many
but not all of the Python tests. All of regrtest still passes outside of tsan.

I've implemented part of the C1x atomic types so that we can explicitly mark
variables that are used across threads, and get defined behavior as compilers
advance.

I've added tsan's client header and implementation to the codebase in
dynamic_annotations.{h,c} (docs at
http://code.google.com/p/data-race-test/wiki/DynamicAnnotations).
Unfortunately, I haven't been able to get helgrind and drd to give sensible
error messages, even when I use their client annotations, so I'm not supporting
them.

Also, improve Makefile's deletion of __pycache__ directories so e.g. 'make
distclean' doesn't fail if no __pycache__ directories exist.

  When such extra options include "-x testname", subsequent arguments

  Issue #6834: replace the implementation for the 'python' and 'pythonw' executables on OSX.

  The previous implementation used execv(2) to run the real interpreter, which means that
  you cannot use the arch(1) tool to select the architecture you want to use for a
  universal build because that only affects the python/pythonw wrapper and not the actual
  interpreter.

  The new version uses posix_spawnv with a number of OSX-specific options that ensure that
  the real interpreter is started using the same CPU architecture as the wrapper, and that
  means that 'arch -ppc python' now actually works.

  I've also changed the way that the wrapper looks for the framework: it is now linked to
  the framework rather than hardcoding the framework path. This should make it easier to
  provide pythonw support in tools like virtualenv.
