Synchronize Coda kernel module definitions in our coda.h to Coda 6's

coda.h:

- CodaFid typdef -> struct CodaFid throughout.
- Use unsigned int instead of unsigned long for venus_dirent and other
  cosmetic fixes.
- Introduce cuid_t and cgid_t and use instead of uid_t and gid_t in RPCs.
- Synchronize comments and macros.
- Use u_int32_t instead of unsigned long for coda_out_hdr.

With these changes, a 64-bit Coda kernel module now works with
coda6_client, whereas previous userspace and kernel versions of RPCs
differed sufficiently to prevent using the file system.  This has been
verified only with casual testing, but /coda is now usable for at least
basic operations on amd64.
