[PATCH] xfs_lsprojid: show quota project id for specified files

[Arkadiusz Miśkiewicz]

There is no simple way for extracting quota project id for specified
files, so here is a shell wrapper which makes this easy thing:

/home/something/aaa: 107919
/home/something/bbb: 107923

Looks generally good, but is there any reason not to make it available
to normal users?  The only problem would be that we'd need to run
the original script through autoconf to generate one that contains
an absolute path to the xfs_io binary.

Also can you hack up a trivial man page for it, please?
