362a4a0bd5 Yes, it was a cool trick >20 years ago to use "0123456789abcdef"[a] to 
implement, xtoa(), but I think defining the samestring 50 times is a bit
too much. Defined HEXDIGITS and hexdigits in subr_prf.c and use it...

c5544c42b5 nfsrv_rcv: don't do so_receive from socket upcall context. 
while there's little benefits, it complicates locking and confuses
flow control.

e633e8b61b - Define a VFS_ATTACH() macro that places a reference to a vfsops structure 
into the "vfsops" link set.
- Use VFS_ATTACH() where vfsops are declared for individual file systems.
- In vfsinit(), traverse the "vfsops" link set, rather than vfs_list_initial[].

8975a0856f adjust the UBC mapping code to support non-vnode uvm_objects. 
this means we can no longer look at the vnode size to determine how many
pages to request in a fault, which is good since for NFS the size can change
out from under us on the server anyway.  there's also a new flag UBC_UNMAP
for ubc_release(), so that the file system code can make the decision about
whether to cache mappings for files being used as executables.

4fd5a025bf nfs_request: a workaround for servers doing "maproot". 
for i/o requests which are expected not to fail due to permission
to mimic unix file open semantics (READ, WRITE, COMMIT),
try two credentials.  namely, the file owner's one and open time one.
remember which credential worked in per-file basis and try it first
next time to minimize number of retries.
ideas from Chuck Silvers.  PR/23716 and PR/24987.

45a21b76f0 Fixing age old cruft: 
* Rather than using mnt_maxsymlinklen to indicate that a file systems returns
  d_type fields(!), add a new internal flag, IMNT_DTYPE.

Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
  in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
  FS-specific checks littered throughout the code.  This may be used later to
  make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
  to implementation issues.

Sync some bug fixes from FFS into ext2fs, particularly:
* ffs_lookup.c 1.21, 1.28, 1.33, 1.48
* ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67
* ffs_vnops.c 1.84, 1.85, 1.86

Clean up some crappy pointer frobnication.

XXX the address on the top of in_ifaddrhead is likely 127.0.0.1.
using it to construct the verifier doesn't make much sense.
maybe it's better to use some uuid or ip_randomid-like method.
