directory cookie that may be thrown back at us from userspace, up
to a size limit. Fixes double entry problem.
* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
value of 8k.
* Various other things that I forget, all related to the dir caching

John Woods, jfwfrom: @ksr.com. also, fixes the following problems:
the va_gen field is in a similar position
(Suns are going to be reporting the change-date microseconds as their
"generation"), I've supplied my own set of diffs below for your inspection.
Note these aren't even compiled, but they're pretty similar to what I had
to do to our older version of OSF/1 here. (There's also an unrelated change
supplied for xdr_subs.h; the pointer types supplied to the fxdr_time() and
txdr_time() macros are not, in fact, both struct timevals. That turns out
to be one of many tips-of-the-iceberg facing those porting the (old) Berkeley
NFS code to 64-bit machines...)
