actually remove unnecessary includes

from Edgar Pettijohn, ok and with input from tb@

The variable errmsg can be static in main.c if code in re.c uses an own
buffer to construct error messages.

with input by and ok millert@

Define functions as static when they are not used outside their own c-files.

ok millert@

Mark static globals that are only used in their respective .c files.
Also make stdin unbuffered since that is the same as using a
single-byte buffer. OK tobias@

Remove useless pattern_t typedef, POSIX regex is here to stay so
just use regex_t directly.

Remove #ifdefs for non-POSIX systems. Also remove #ifdef for
SIGWINCH, it is not POSIX but it is a defacto standard.
OK deraadt@

use atomic operations on sig_atomic_t variables inside the signal handlers,
rather than sharing one variable unsafely.
ok millert

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_N

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

Remove prototypes for functions that were already removed.
From Benjamin Scher Purcell.

remove nonstandard DES support because DES. ok beck deraadt miod

remove sunos backwards compat
ok guenther

There is no filter_lines function, remove its prototype. From Mark Lumsden.

Kill unneeded longs; fixes some minor 64 bit issues. deraadt@ OK

Manual cleanup of remaining userland __P use (excluding packages maintained outside the tree)

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be don

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Fix prototypes

cleanup strcpy, strncpy, signal races, etc

Back out my sprintf -> snprintf changes where they don't make sense and
use good ole strcpy() instead. Also use perror() instead of fprintf()
where it makes sense.

sprintf -> snprintf paranoia
