gssd: include gssapi/gssapi.h before write_bytes.h
In gssd/context_lucid.c, ensure that gss_buffer_desc and gss_OID_desc
are defined before write_bytes.h, which uses these definitions, is
included. With TI-RPC, these definitions are not provided by
rpc/rpc.h.
It appears that <gssapi/gssapi_krb5.h> already includes krb5.h and
gssapi.h (on my system, anyway) so let's drop those includes.
Ideally write_bytes.h itself should include the needed headers, but
some source files that use Heimdal include a different, Heimdal-
compatible, header to get these definitions.

mount.nfs: squelch compiler warning for TI-RPC builds
The printf format string in nfs_pp_debug() assumes the @program and
@version arguments are unsigned long, because the legacy RPC headers
define both rpcprog_t and rpcvers_t as unsigned long types.
However, the TI-RPC headers define both types as uint32_t, which
requires a different printf format type. If we replace the legacy
headers with TI-RPC headers, this type mismatch generates compiler
warnings that are nothing but noise.
We are about to provide a switch at ./configure time to allow the use
of either the legacy RPC headers or the TI-RPC headers, so we need
a printf format that works in both cases.
To squelch the compiler warnings that occur when using the TI-RPC
headers, cast both arguments in the fprintf statement to the widest of
the two types ("unsigned long" or "uint32_t").

Exportfs and rpc.mountd optimalization
There were some problems with exportfs and rpc.mountd for long export
lists - see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76643
I do optimalization as my bachelors thesis (Facuulty of informatics,
Masaryk's university Brno, Czech Republic), under lead of Yenya
Kasprzak.
Both exportfs and rpc.mount build linked list of exports (shared
functions in export.c). Every time they are inserting new export into
list, they search for same export in list.
I replaced linked list by hash table and functions export_add and
export_lookup by functions hash_export_add and hash_export_lookup
(export.c).
Because some other functions required exportlist as linked list, hash
table has some implementation modification im comparison with ordinary
hash table. It also keeps exports in linked list and has pointer to
head of the list. So there's no need of implementation function
<for_all_in_hash_table>.

umount.nfs command: Support AF_INET6 server addresses

stuffer
function nfs_options2pmap(). Mount option parsing for umount.nfs now
works
the same as it does for mount option rewriting in the text-based
mount.nfs
command.
This adds a number of new features:
1. The new logic supports resolving AF_INET6 server addresses
2. Support is added for the recently introduced "mountaddr" option.
3. Parsing numeric option values is much more careful
4. Option parsing no longer uses xmalloc/xstrdup, so it won't fail
silently if memory can't be allocated
5. Mount program number set in /etc/rpc is respected
6. Mount doesn't exit with EX_USAGE if the hostname lookup fails

text-based mount command: fix return value from po_rightmost()
Recently commit 0dcb83a8 changed the po_rightmost() function to
distinguish among several possible mount options by taking a table
containing the alternatives, and returning the table index of the
entry which is rightmost in the mount option string.
If it didn't find any mount option that matches an entry from the
passed-in table, it returned zero. This was the same behavior it had
before, when it only checked for two options at a time. It returned
PO_NEITHER_FOUND, which was zero.
Since this is C, however, zero also happens to be a valid index into
the passed-in array of options.
Modify the po_rightmost() function to return -1 if the entry wasn't
found, and fix up the callers to look for a C-style array index that
starts at zero.
Thanks to Steve Dickson for troubleshooting the problem. His solution
was merely to bump the return value, as callers already expected an
ordinal index instead of a C-style index.
I prefer this equivalent but slightly more extensive change because it
makes the behavior of po_rightmost() more closely match how humans
understand C arrays to work. Let's address some of the confusion that
caused this bug, as well as fixing the run-time behavior.
