this should reduce but perhaps not eliminate the VLRU cycle: increase
-stat parameter problem on Linux as it's not yet clear that this is the
only problem and circumstantially it is probably not.
this cuts rpc traffic in half for directories on which you have
no permissions and is capable of doing more if a useful way can
be conceived of caching errors.
currently bulkstat works thus:
say a directory has 100 files. bulkstat will on the first hit stat
the first 30 files, integrating the information if successful,
and when you hit file 31, repeat. meaning if you can read that 100 files
is 4 bulkstatus rpcs (3*30+10). if you can't, you do bulkstatus, get an abort,
then do fetchstatus on the file and find out why you lost. you go on and
try bulkstatus again this time for files 2-31 instead of 1-30. same failure,
meaning you do 2N rpcs for the N files. inlinebulk doesn't abort but instead
fills in stat info for any of the up to 30 files it can, and errors for
any it can't.
currently the client will pull out any stat info filled in,
and then return the error from the first file, meaning if you can't
read the directory we do N inlinebulk rpcs instead of N bulkstatus +
N fetchstatus rpcs. if the errors for the other 29 could be meaningfully
cached (and you have to be careful not to pollute information
such that it's not useful for someone in a different auth context) then
we could get down to the same 4 rpcs we have for success, but that's an
exercise for later give how the cache manager works.

there were some cases where we falsely reported the BZNOENT from salvage-tmp
being cleanup up as "bos: failed to start 'salvager' (no such entity)"..
despite having just reported:
bos: salvage completed
this should no longer happen.
-- /vicepX/AFSIDat/README is created the first time the fileserver
is started, rather than the second time.
-- For the namei fileserver, /vicepa/Lock/vicepa is created as
the lockfile. Previously, on Solaris, the raw device was
was being used for LockPartition(), and that breaks when
there isn't a corresponding device.
-- The VolPartitions and XVolPartitions volserver calls now return
the list of attached (rather than mounted) partitions. This is
consistent with the NT fileserver and removes duplicate code.
The actual magic for allowing the fileserver to attach non-mounted
partitions is to create /vicepX/AlwaysAttach.

carefully avoid non vicep directories and/or partitions as it may get upset at

more carefully avoid non-vicepX partitions
previously and since 3.5 rx enhancements fileserver would delay 3 seconds
on sending an rx abort when the abort was the 11th or more occurance of
the same error on the same call. the problem was fetchstatus/bulkstatus
on a directory on which you have "l" but not "r" would take forever after the
first 5 files (bulkstatus and then fetchstatus on each file, 2*5=10)
so in FetchStatus and BulkStatus stubs we suppress repeated errors from
Check_PermissionRights *only*, which has the effect of suppressing the
problem without removing the theoretical benefit of avoiding letting any
one client throw requests at as as fast as we can abort them unless those
requests happen to be fetch/bulkstat requests which fail a permission check,
but in order to avoid that we'd also need to cache what they last tried
to stat, and then things would get ugly.

The rxi_ReceiveAckPacket() change makes sure we have two extra fields
(the max and recommended packet sizes) hanging off the packet, rather
than just one.
The PKTFLAG_FREE stuff in rx_packet.c just initialized flags in case
PKTFLAG_ACKED somehow didn't get cleared there.
The wirevec changes are off-by-1 errors: there's p->niovecs iovecs
in a packet, from 0 (header) to p->niovecs-1, so p->niovecs doesn't
refer to a meaningful iovec.
1) Removal of unused variables
2) some NT ifdef cleanup
3) use of size_t rather than int to store the result of strlen()
4) some bugs that really only occured when errors occured.
5) some functions were implicitly declared as 'int' but doing a
"return;" Some I declared as 'void' and prototyped them; some I
just returned a value.

according to jeff:
- Renames the top-level 'install' target to 'build'. This should be
transparent, since no one should be using that.
- Improves on Sam's dirpath patches, by splitting out server binaries
into separate bin, sbin, and libexec directories in GCS mode (these
are all /usr/afs/bin in Transarc mode).
- Updates the top-level 'all' target so that it builds the software
but does not generate a dest tree. Top-level 'lib' and 'include'
directories are generated to hold the intermediate libraries and headers
used during the build.
- Adds a new top-level 'install' target, which installs things in the
appropriate directories under ${DESTDIR}, based on configure's install
directories plus the extras added by Sam's patch.
- Adds a new top-level 'dest' target, which creates an old-style dest
directory under ${DEST}. The ${DEST} variable defaults to the
traditional value of ${SRCDIR_PARENT}/${SYS_NAME}/dest. Note that
this variable used to be called ${DESTDIR}; it was renamed to avoid
conflicts with the de facto standard usage of ${DESTDIR}.
