* Fix yacc parser error recovery so that setjmp(3)/longjmp(3) is unnecessary.
* Fix SIGURG handler to set an urgflag that's later tested, rather than
abusing setjmp(3)/longjmp(3).
* Use "volatile sig_atomic_t" as the type of variables modified by sig handlers.
* Use sigaction(3) instead of signal(3) to set the signal handlers.
* Only set the main SIGALRM handler once. If we need to change it,
cache the old handler and restore appropriately...
* Remove a bunch of signal races by improving the signal handlers.
* Fix memory leak with 'ESPV ALL'.
My stuff:
* Clean up the debug message in reply(); use vsnprintf(3) instead of vsyslog(3).
* Rework parsing of OOB commands to _not_ use the yacc parser, since the
latter isn't reentrant and the hacks to work around that are ugly.
We now examine urgflag at appropriate locations and call handleoobcmd()
if it's set. Since the only OOB commands we currently implement are
ABOR and STAT, this isn't an issue. (I also can't find the reference in
RFC2228 where MIC, CONF & ENC are OOB-only commands. Go figure.)
I could clean up the is_oob stuff some more, but the remaining stuff
in ftpcmd.y is harmless and it's unnecessary churn right this moment.
* Don't call handlers for functions that are not enabled.
* Always call the handler if the function doesn't support the STATUS register.
While I'm here, divide the CCR numbers by 2.
case (ne@pcmcia) where we were using these to create a subregion, it is better
handled by calling bus_space_subregion().
Now there is a 1:1 mapping between I/O spaces in the config table and windows
mapped in the function. Rework the multifunction mapping code to take
advantage of this by using both I/O base addresses if necessary.
rebuilt from "newer than" to "not older than". The latter check also
manages to take into account cases where the db file doesn't yet exist
because the source is "not older than" something that doesn't yet
exist.

- SIOCAIFADDR, SIOCSIFADDR: free an address on error.
- SIOCSIFNETMASK, SIOCSIFDSTADDR: reject operations for an interface which
has no AF_INET addresses.

* Don't splnet() in xi_init() -- the callers do that.
* Don't do the enable call in xi_init() -- it should be done only in a process
context so it can sleep.
* Call xi_start() at the end of xi_init() to restart output.
* If the interface is already up, we only need to call xi_set_address() to
change state on SIOCSIFFLAGS.
