0c893d623c Change from using poll(2) to kqueue/kevent when waiting for a DNS
response to return.  This will stop processes waiting on DNS requests
from being woken up when a select collision occurs.  This was tested
on mx1.FreeBSD.org (outgoing mail for the FreeBSD.org mailing
lists.)

8d25eb2c3a Add code to devname(3) so it can find the names of devices which
were not present when dev_mkdb(8) was run.

First the dev_mkdb(8) database is searched, this caters for non-DEVFS
cases where people have renamed a device.

If that fails we ask the kernel using sysctl kern.devname if the device
driver has put a name in the dev_t.  This covers DEVFS cloned devices.

If that also fails we format a string which isn't entirely useless.

b777873ec1 Disallow '/' characters in LC_* environment variables which might
be used to point to a bad locale file. This is only believed to be a
minor security risk - the only risk is if some program uses the result
of a localized string as a format specifier in a vulnerable function
like sprintf(). No such code is believed to exist in the FreeBSD base
system, although it is possible that badly written third party code
would do that.

248aee623c Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.

7aa1d9cd4a Remove the SIGSYS handler and wrapper around the __getcwd() syscall.
It was kinda silly since the sigaction() syscall that it used to setup
the handler is more recent than __getcwd(), therefore it was useless
as the wrapper would have died before even getting as far as __getcwd(2).

49b8dd0db5 Finaly cleanup libc/nls code:
* rewrite catopen() to remove duplicate code chunks and optimize
* if empty string is passed to catopen() as name argument then
   catopen() will set errno to ENOENT (File not found), not EINVAL
* move search code to LOOKUP() macro to shrink amount of duplicated code
* move common resource freeing actions to __nls_free_resources() function
* exclude from build code related to MCLoadAll defintion since it is not
  using at all
* style(9) related whitespace changes

e9d918edb6 Don't print an error message if the bad option is '?'. This has been
in my tree for a long time.  bde reviewed this once upon a time and
said it was OK, iirc.  This also obviates the need to put ? in the
optstring argument to preclude the extra warning message which some
people think confuses users.  When I made my getopt cleanups of a long
time ago, this was the compromise reached.  I just neglected to commit
it until now.

9feac5c218 Move setproctitle() from libutil to libc (after a repo-copy)

setproctitle() is prototyped in unistd.h as opposed to stdlib.h
where OpenBSD and NetBSD have it.
