1a7425f67a Issue #18203: Replace malloc() with PyMem_RawMalloc() at Python initialization 
* Replace malloc() with PyMem_RawMalloc()
* Replace PyMem_Malloc() with PyMem_RawMalloc() where the GIL is not held.
* _Py_char2wchar() now returns a buffer allocated by PyMem_RawMalloc(), instead
  of PyMem_Malloc()

99563b1df8 calculate_path() decodes the PYTHONPATH environment variable from the locale 
encoding using _Py_char2wchar() instead of mbstowcs() to store undecodable
bytes as surrogates characters (PEP 383) instead of ignoring silently
the PYTHONPATH variable.

47f637ce17 getpath.c: fix test to detech PyUnicode_AsWideChar() failure 
PyUnicode_AsWideChar() result is signed, whereas it was stored in a unsigned
variable, and then the test was "n >= 0" which is always true to an unsigned
number. Patch written by Hallvard B Furuseth.

ae4836df6d Issue #6011: decode PREFIX, EXEC_PREFIX and PYTHONPATH variables using 
_Py_char2wchar(), instead of L"" VAR hack, to escape undecodable bytes using
the surrogateescape error handler.

2158231433 Issue #6011: getpath: decode VPATH env var from the locale encoding 
Instead of casting it to wchar_t* without conversion. It fixes a bug if Python
is compiled a non-ascii directory, different than the source code directory,
with C locale.

61aad57dc9 Oops, fix my previous commit (r85583) on calculate_path() 
path value may be changed, so keep a copy in a new variable.

4f3abb0f09 copy_absolute() keeps the relative path on _Py_wgetcwd() failure 
.. instead of raising a fatal error. Even if the current directory was deleted,
use relative paths may still work (eg. run Python with "../python").

e9b428f997 Reimplement addbuilddir() in C inside getpath.c, so as to execute it 
at interpreter startup before importing any non-builtin modules.
Should fix #9589.
