setup: detect Python DLL filename from loaded DLL
Attempting to build Mercurial from source using MinGW from
msys2 on Windows produces a hg.exe that attempts to load e.g.
python27.dll. MinGW prefixes its library name with "lib" and
adds a period between the major and minor versions. e.g.
"libpython2.7.dll."
Before this patch, hg.exe files in a MinGW environment would
either fail to find a Python DLL or would attempt to load a
non-MinGW DLL, which would summarily explode. Either way,
hg.exe wouldn't work.
This patch improves the code that determines the Python DLL
filename to actually use the loaded Python DLL instead of
inferring it. Basically we take the handle of the loaded DLL
from sys.dllhandle and call a Windows API to try to resolve
that handle to a filename.
