The creation of inline wrappers ext2fs_open() and ext2fs_stat()
in commit c859cb1de0d624caa0779fb17d1a53766143136e in ext2fs.h
caused difficulties with the use of headers, since the headers
for open64() and stat64() may already be included (and skip the
declaration of the 64-bit variants) before ext2fs.h is ever read.
There is no real way to solve the missing prototypes and resulting
compiler warnings inside ext2fs.h.
Since ext2fs_open() and ext2fs_stat() are not performance critical
operations, they do not need to be inline functions at all, and
the needed function headers can be handled properly in one file.
Similarly, posix_memalloc() was having difficulties with headers,
and was being defined in ext2fs.h, but it is now only being used
by a single file, so move the required header there.
