There is a clear separation of the crypto telnet and the non-crypto telnet.
As this is the non-crypto version, remove the useless (commented out)
directives and macros.
Add support to the host driver for "downloaded constants". These are immediate
operands that are set during seqeuncer program download instead of at
assembly time.
Remove the REJBYTE sram variable. The host driver can just as easly
read the accumulator to get this value.
This should fix the reported problems with cards that don't have devices
attached to them failing with a stream of "Somone reset bus X" messages.
Doug Ledford determined the cause of the problem, fixes by me.
Add support to aicasm for "downloaded constants". These are immediate
operands that are set during seqeuncer program download instead of at
assembly time.
Convert the sequencer code to use" downloaded constants" for four run time
constants that vary depending on the board type. This frees up 4 bytes
of sequencer scratch ram space where these constants used to be stored and
also removes the additional instructions required to load their values
into the accumulator prior to using them.
Remove the REJBYTE sram variable. The host driver can just as easly
read the accumulator to get this value.
The scratch ram savings is important as the old code used to clober the
SCSICONF register on 274X cards which sits near the top of scratch ram
space. The SCSICONF register controls bus termination, and clobbering
it is not a good thing. Now we have 4 bytes to spare.

Clustered read and write are switched at mount-option level.
1. Clustered I/O is switched by the MNT_NOCLUSTERR and MNT_NOCLUSTERW
bits of the mnt_flag. The sysctl variables, vfs.foo.doclusterread
and vfs.foo.doclusterwrite are deleted. Only mount option can
control clustered I/O from userland.
2. When foofs_mount mounts block device, foofs_mount checks D_CLUSTERR
and D_CLUSTERW bits of the d_flags member in the block device switch
table. If D_NOCLUSTERR / D_NOCLUSTERW are set, MNT_NOCLUSTERR /
MNT_NOCLUSTERW bits will be set. In this case, MNT_NOCLUSTERR and
MNT_NOCLUSTERW cannot be cleared from userland.
3. Vnode driver disables both clustered read and write.
4. Union filesystem disables clutered write.
1) Bring '!!' back since we wan't overflow even a char
2) Revive __maskrune, just return mask now
3) Express __istype via !!__maskrune
4) Use __maskrune in digittoint
tiny update of ESC sequence parser.
- some addition of comments (for readability)
- iso-2022 G0 designation support. This does almost nothing. Just for
avoiding garbled screen when got "ESC ( B".
(how about G1/2/3 designation? I'm not sure)
Oops, wrong version of digittoint fix was commited, step back to v1.8
instead just remove '!!' to make digittoint() work and re-arrange
things a little
Reduce the target number of vnodes on the freelist from desiredvnodes
(usually a couple of thousand) to 25. The measured impact on cache-hits
doesn't justify spending memory this way:
Target number of free vnodes versus namecache hit rate in % during a
make world:

200 98.5479

3000 98.6006
4000 98.6126

Fix a bug where the speculative memory probe wouldn't occur on systems that
report slightly more than 64MB of total memory. This can happen due to the
total being the sum of both base and extended memory.

Initial import of the new kerberosIV Makefiles.
I will follow up with the userland sources over the next few days.
The impatient of you can play with this, but you do this without
support or blessing until I am finished ;-)
Store an absolute tick value in callout entries so that a subtraction on
hash chain traversal isn't needed. This also allows untimeout to recompute
the hash to find the bucket that the entry to remove is stored in so
that each callout entry no longer needs to store that information.
Add one more counter so we can truly find out how good our name cache
is. If we don't find something and don't what to have found something,
it's actually a success.

Use usleep to handle nonull case

data modifications
