Reduce the size of a number of race windows in the TCP socket options
processing code: a RST may arrive during a socket option call, causing
the PCB to be freed, leading to an invalid pointer dereference. When
the kernel blocks in a socket option copyin or memory allocation (such
as during heavy paging), the race window is greatly widened. This
change re-validates the PCB pointer after returning from the copy/alloc
operation. This does not eliminate the problem, but does narrow the
window significantly (to the point where it may not be observed at all).
The proper fix is in 7.x, which significantly re-works the socket and
PCB code so that PCB's are not ripped out from under sockets on reset.
However, those changes are not appropriate for an MFC during a release
cycle. As a result, this is not an MFC, but new code crafted for 6.x.

MFC: Various uthread fixes:
- Delay setting wakeup time until after poll array has been allocated.
Blocking on the malloc spinlock would cause the select timeout to be lost.

- Delay unblocking signal and restoring process signal mask until the
thread signal mask has been updated to avoid stack overflow during signal
bursts.
Don't block signal forever if no threads can currently handle signal.
Check for pending signal after direct invocation of signal handler.

Unbreak syscons' support for ddb mode by reactivating old fixes
(syscons.c 1.331 and 1.372 are reactivated by restoring this part of
db_interface.c (i386 version 1.48, ...) in a different file).
This is not a MFC because larger changes than I have time for are
needed there.
The most noticeable effect of this fix is that syscons switches to the
console vty on entry to ddb. The most important effect of this fix
is that switching vtys in ddb doesn't try (and sometimes succeed) to
crash the system by calling wakeup().
