PATCH: Adjust for more Windows oddities

- Reply-to: mark at codesourcery dot com
Windows does not have getuid or getgid, so I've added autoconf checks
for those functions. There is also no "st_blksize" member in "struct
stat". Technically, this patch should perhaps be two separate
patches, but since the code modified in remote-fileio.c was all in the
same place, I've submitted it as one patch.
Tested on x86_64-unknown-linux-gnu. OK to apply?
(After this patch, we'll be on to the "good part".)
