`warn'. Now a whole 2 members of the err() family don't cause pollution.

This fixes world breakage in awk for NOSHARED worlds. contrib/awk/msg.c
has had its own version of err() for a long time, but this somehow
didn't cause problems until the update to awk-3.1.0.

Fixed namespace pollution related to `warn' in libc (but not in other
libraries or for other members of the err() family).

This fixes world breakage in bc and rcs/* for NOSHARED worlds.

Replace accidentally-deleted `x' which caused warnx() to misbehave.

- Add a new flavor of the err(3) family, which takes an explicit

will make it easier to use these functions in conjunction with
modern library interfaces that return an errno value explicitly.

Don't use __dead or __pure in user code. They were obfuscations
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

Add err_set_file() and err_set_exit() functions to make it possible for
programs which use err(3) to work nicely in a wider range of environments
(e.g., dialog).
