data endpoints. The control endpoint doesn't need read/write/poll
operations, and more importantly, the thread counts should be
separate so that the control endpoint can properly reference itself
while deleting and recreating the data endpoints.
* Add some macros that handle referencing/releasing devices, and use them
for sleeping/woken-up and open/close operations as apppropriate.
* Use d_purge for FreeBSD, and a loop testing the open status for all
the endpoints for NetBSD and OpenBSD, so that when the device is
detached, the right thing always happens.
restart the current waiting transfer. If this isn't done, the device's
next transfer (that we would like to do a short read on) is going to
return an error -- for short transfer.
* For bulk transfer endpoints, restore the maximum transfer length each
time a transfer is done, or the first short transfer will make all the
rest that size or smaller.
* Remove impossibilities (malloc(M_WAITOK) == NULL, &var == NULL).
Disable some code which magics minor numbers into card/port numbers.
I think we will have to parse this from the device name in the future,
but I need to confer with peter@ about this.
Put sicontrol back in the build.

New device names are "{tty|cua}A$(card)$(port)[.init|.lock]"
Put a portname in the port structure if SI_DEBUG is defined to avoid
need to inspect minor number to construct name..
Constify some strings.
Remove duplicated DBG_ #defines.
uses predate the change in the pmap_enter() interface that replaced the
page's physical address by the address of its vm_page structure. The
PHYS_TO_VM_PAGE() was being used to compute the address of the same vm_page
structure that was being passed in.

help for determining what to bump provided by kris.

is a no-op on little endian architectures, but fixes getting the MAC
address for some dc(4) cards on big endian architectures.
This is a RELENG_5 candidate.

1. Process p1 is currently being swapped in.
2. Process p2 calls linux_ptrace(PTRACE_GETFPXREGS, p1_pid, ...)
3. After acquiring a reference to FIRST_THREAD_IN_PROC(p1),
p2 blocks in faultin() while p1 finishes being swapped in.
This means p2 won't get back the lock on p1 until after p1's
threads are runnable.
4. After p1 is swapped in, the first thread in p1 exits.
5. p2 now uses its dangling reference to p1's first thread.
