Fix a segfault when b"" was passed to b2a_qp() -- it was using strchr()
instead of memchr().

Merge change 54983 from the trunk:  Add the locale "English" to test_locale.py for a windows run, since "En" isn't legal for the Visual C 8 runtime.  This update restores full testsuite compliance to VisualStudio 2005 builds, apart from unavailible external modules.

Merge change 54982 from the trunk.  This fixes the test_subprocess test in the testsuite for VisualStudio2005 builds, by "sanitizing" the "mode" that is used in the posixmodule's fdopen(). In particular the non-standard "U" mode character is removed.

the nb_long slot on classobject instances now defaults to call the nb_int slot member if there is no __long__ attribute found.  This is in accordance with a suggestion from Armin Rigo, and allows the test_getargs2.py test in the testsuite for x64

Fix two problems that emerged when the testsuite was run with an x64 build:  PyLong_FromSSize_t incorrectly assumed an unsigned object, and itertools.count() had the wrong upper limit for the iterator.

Fix NonRecursiveMutex on x64.  The signature of the faux-InterlockedCompareExchange function was wrong:  It works with LONG and not PVOID objects, and it needs to have the target marked as volatile.  Further, it is not needed at all for x64 targets, since that platform always has the real McCoy.

Fix those parts in the testsuite that assumed that sys.maxint would cause overflow on x64.  Now the testsuite is well behaved on that platform.

Clarify the behaviour of PyUnicode_DecodeUTF16(): A BOM is only skipped
in native order mode, and only if it's the first two bytes.

  When accessing the .value attribute of a c_wchar_p instance, and the
  instance does not point to a valid wchar_t zero-terminated string,
  raise a ValueError.  c_char_p does this already.

  The ValueError message now contains the correct pointer address.

  Will backport to release25-maint.

Additional changes to the property sheets in PCBuild8.  Visual Studio doesn's save those when it builds, unlike the .vcproj files, so I chekced in out-of-date versions.

Undefine the Yield macro after including Python_ast.h where it may cause conflicts with winbase.h on Windows.

Complete revamp of PCBuild8 directory.  Use subdirectories for each project under the main pcbuild solution.  Now make extensive use of property sheets to simplify project configuration. x64 build fully supported, and the process for building PGO version (Profiler Guided Optimization) simplified. All projects are now present, except _ssl, which needs to be reimplemented.  Also, some of the projects that require external libraries need extra work to fully compile on x64.

  Make sure to call PyErr_NoMemory() in several places where
  PyMem_Malloc() could potentially fail.

  Will backport to the release25-maint branch.

the changes are to support multiple versions (ie, trunk and 2.5).
Also check for conflicts in the .tex file when a release is cut.

the locale changes between calls.

leads to undefined behaviour.
