Reimplement distutils.spawn.spawn() function with the subprocess
module.
setup.py now uses a basic implementation of the subprocess module if
the subprocess module is not available: before required C extension
modules are built.
shutil.which() and distutils.spawn.find_executable() now use
os.confstr("CS_PATH") if available instead of os.defpath, if the PATH
environment variable is not set.
Don't use os.confstr("CS_PATH") nor os.defpath if the PATH
environment variable is set to an empty string to mimick Unix 'which'
command behavior.
Changes:
* find_executable() now starts by checking for the executable in the
current working directly case. Add an explicit
"if not path: return None".
* Add tests for PATH='' (empty string), PATH=':' and for PATHEXT.
When running external programs such as a C compiler and getting an
error code, distutils only prints the program name. With this change,
one can get the full command line by setting the DISTUTILS_DEBUG
environment variable.
This should have no compatibility issues, unless there are tools
that depend on the exact format of distutils debug messages.
set the MACOSX_DEPLOYMENT_TARGET env variable for the interpreter process
on OS X. This could cause failures in non-distutils subprocesses and was
unreliable since tests or user programs could modify the interpreter
environment after distutils set it. Instead, have distutils set the
the deployment target only in the environment of each build subprocess.
Continue to use the previous algorithm for deriving the deployment target
value:
if MACOSX_DEPLOYMENT_TARGET is not set in the interpreter's env:
use the interpreter build configure MACOSX_DEPLOYMENT_TARGET
elif the MACOSX_DEPLOYMENT_TARGET env value >= configure value:
use the env MACOSX_DEPLOYMENT_TARGET
else: # env value less than interpreter build configure value
raise exception
This allows building extensions that can only run on newer versions of
the OS than the version python was built for, for example with a python
built for 10.3 or later and an extension that needs to be built for 10.5.

improved distutils.spawn test coverage + cleaned it up

There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.
(Oh, and I don't know if the compiler package works.)
This is a conservative version of SF patch 504889. It uses the log
module instead of calling print in various places, and it ignores the
verbose argument passed to many functions and set as an attribute on
some objects. Instead, it uses the verbosity set on the logger via
the command line.
The log module is now preferred over announce() and warn() methods
that exist only for backwards compatibility.
XXX This checkin changes a lot of modules that have no test suite and
aren't exercised by the Python build process. It will need
substantial testing.
