We never want to accept a short read or a short write when
transferring data to or from a local file.
Either the entire read (or write) completes or the operation
failed and we will not recover gracefully from it.

These are easily built off the standard C library functions memcpy
and memcmp. By marking these inline we stand a good chance of
the C compiler replacing the entire thing with tight machine code,
because many compilers will actually inline a memcmp or memcpy when
the 3rd argument (the size) is a constant value.

This way we can start to write IO code to read and write files in the
Git object database, but provide a hook to inject native Win32 APIs
instead so libgit2 can be ported to run natively on that platform.
