Fix a race condition where if a process is asleep waiting on an
exclusive lock of a ccd device while another process is unconfiguring
that same device, the first process would never awaken (unless interrupted).

If the read or write request can fit into a 6-byte cdb, then
use a 6-byte cdb, otherwise use the 10-byte as before.
In sdattach(), make a note if the device is "ancient" (i.e.
inqbuf.version & SID_ANSII == 0).
Implement sdminphys(): if the device is "ancient", shorten the
transfer so it will fit into a 6-byte cdb.
In sdminphys(), add a comment about the semantics of the "length" field
in a 6-byte read/write cdb (namely, length == 0 really means 256), and
that we handle this conservatively by limiting the transfer to 255 blocks.
*sigh* One just never knows how a pre-scsi-1 device is going to behave.
Remove a couple of now unneeded assignments.

Only expect vm_fork() to return if __FORK_BRAINDAMAGE is defined.
Use splstatclock() rather than splhigh() in one place.
Eliminate unused third arg to vm_fork().

Extend use of vm_object_prefer() to vm_allocate_with_pager().
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.
Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.

Still incomplete, but much more complete FPE from Ken Nakata
<kenn@remus.rutgers.edu>. This emulator does not yet emulate
the following functions:
FSINH, FETOXM1, FTANH, FATAN, FASIN, FATANH, FSIN, FTAN,
FETOX, FTWOTOX, FTENTOX, FCOSH, FACOS, FCOS, FSINCOS
It is sufficient, however, to allow programs like df, w, and newfs,
to run to completion with correct results.
Portions of this code were based on the sparc fpe and on initial
work by gwr.

"goto start" after sleeping for locked iso_node in cd9660_lock, like
in ufs_lock.
NBPG may not be computable by the preprocessor. Make "do clustered io"
a run-time decision. Note: the compiler can optimize it away.

Win95 ignores case on lookup
Really don't generate long names when mounted with -s
Fix cookie handling
Don't forward credentials to bread, it makes nfs panic
(Of course, nfs shouldn't rely on the credentials not being referenced)
Don't give directory entry to deget, it could result in a deadlock
Use device blocks, not clusters for logical block numbers
Add support for Win'95 separate creation/modification/access timestamps
Re-introduce lowercase filenames for non-Win'95-filesystems
Fix thinko with block boundaries in directories
Don't overwrite dirclust, it's needed later on
Enable flock(2).

When converting from termios to sgtty, if RAW is set, use the previous
settings of LITOUT and PASS8, since these cannot be determined from the
termios modes.

1) undef various EXEC_ cpp symbols before defining them, in case
they're already defined for some reason (this can happen
on the alpha, for example, which needs to define EXEC_ECOFF
in the std.alpha config file).
2) add hpux compat

represent profiling size, scale more correctly (as size_t, u_int, resp.)
