Adds fgetxattr/fsetxattr/fremovexattr support for Mac OSX, Solaris, FreeBSD

This wish was initiated due to a bug in the World of Warcraft launcher:

If only there were a wine configuration setting to cause
server/file.c::file_set_sd to:
1) leave the owner permissions intact
2) fake the permission change, or
3) use xattrs to fake the permissions.

The last option would also need an appropriate change to
server/file.c::file_get_sd
server/change.c::dir_set_sd
server/change.c::dir_get_sd
