* name-cache.c (check_lookup_cache): Use name_cache_neg_timeout in
preference to name_cache_timeout for negative hits.
* nfs.h (name_cache_neg_timeout): New variable.
* main.c (DEFAULT_NAME_CACHE_NEG_TIMEOUT): New macro.
(name_cache_neg_timeout): Initialize new variable.
(OPT_NCACHE_NEG_TO): New option key.
(common_options): Add --name-cache-neg-timeout switch.
(parse_common_opt): Process OPT_NCACHE_NEG_TO option key.
* ops.c (netfs_attempt_lookup): Do cast of -1 correctly to match
check_lookup_cache and ANSI C rules.
* name-cache.c (check_lookup_cache): Unlock DIR correctly before
returning a negative cache hit.
* rpc.c (rpc_receive_thread): Don't print "dropping reply"
messages any more.
* ops.c (netfs_attempt_lookup): Cash all lookups, both positive
and negative.
(netfs_attempt_mkdir): Purge cache before creating directory
entry.
(netfs_attempt_link): Likewise.
(netfs_attempt_create_file): Likewise.
* ops.c (netfs_attempt_lookup): Pass correct node to
enter_lookup_cache as the child.

* name-cache.c: New file.
* ops.c (netfs_attempt_lookup): Check lookup cache before trying
RPC. After successful lookup, make cache entry.
(netfs_attempt_unlink): Purge cache before doing operation.
(netfs_attempt_rmdir): Likewise.
(netfs_attempt_rename): Purge cache for both names before operation.
* nfs.h (enter_lookup_cache, purge_lookup_cache,
check_lookup_cache): New prototypes.
* Makefile (SRCS): Add name-cache.c.
* nfs.h (name_cache_timeout): New variable.
* main.c (DEFAULT_NAME_CACHE_TIMEOUT): New macro.
(name_cache_timeout): Initialize new variable.
(OPT_NCACHE_TO): New option key.
(common_options): Add --name-cache-timeout switch.
(parse_common_opt): Process OPT_NCACHE_TO option key.
* cache.c (lookup_fhandle): Don't parse NFS XDR format, instead
take a length arg. Return void. All callers changed to use new
function xdr_decode_fhandle.
* nfs.c (xdr_decode_fhandle): New function.
* nfs.h (xdr_decode_fhandle): New prototype.
(lookup_fhandle): Update prototype.
