Justine Tunney 559b024e1d Decentralize Python native module linkage 
We can now link even smaller Python binaries. For example, the hello.com
program in the Python build directory is a compiled linked executable of
hello.py which just prints hello world. Using decentralized sections, we
can make that binary 1.9mb in size (noting that python.com is 6.3 megs!)

This works for nontrivial programs too. For example, say we want an APE
binary that's equivalent to python.com -m http.server. Our makefile now
builds such a binary using the new launcher and it's only 3.2mb in size
since Python sources get turned into ELF objects, which tell our linker
that we need things like native hashing algorithm code.

the physical target and the print name is shown in directory listings.
- The print name must be a native name, prefixed with "\??\".
- Both names are stored after each other in the same buffer (the
PathBuffer) and both must be NUL-terminated.
- There are four members defining their respective offset and length
inside PathBuffer: SubstituteNameOffset, SubstituteNameLength,
PrintNameOffset and PrintNameLength.
- The total size we need to allocate for the REPARSE_DATA_BUFFER, thus,
is the sum of:
- the fixed header size (REPARSE_DATA_BUFFER_HEADER_SIZE)
- the size of the MountPointReparseBuffer member without the PathBuffer
- the size of the prefix ("\??\") in bytes
