Add missing <time.h> header.

ok joris@

Remove xfree(), like already done for RCS. From Michael W Bombardieri,
ok mmcc

do not need timeb.h

Constrain the 2038 check to only when sizeof(time_t) == sizeof(int).
Adding more powerful checking is too difficult. We'll fix this problem
by moving to 64-bit time_t.. and once we do, we don't want this code to
falsely trigger.
ok millert

Checking for -1 as an overflow value is pretty absurd. Returning
the unix epoch is equally absurd. Just return Start for now. We may
add overflow checks in the future.

OK xsa nicm

Replace abort(), fatal(), and errx() with return -1, since date_parse
returns -1 on error.

OK nicm

Reduce variable/function name and whitespace differences between
cvs/rcs.

OK xsa zinovik

Clean up struct tm handling. Instead of calling gmtime/localtime
and making copies (among other weird dances), use reentrant versions.

Not being able to tell the time is a fatal error, so die if that
happens.

Diff originally from nicm.

OK nicm xsa

* yyInput doesn't seem to contain anything meaningful at the time when
yyerror() is called, so there's no point in printing it
* unbreak `env CFLAGS='-DTEST' make date`

ok joris@

replace abort() by return (-1)

from ray@ suggestion
"looks good" ray@

general includes cleanup sweep. ok joris@ niallo@

Prevent negative array index accesses when strlen(buff) == 0.

OK joris@

sync with usr.bin/rcs version.

Use xasprintf and xfree.

``But i thought it already went in...'' xsa@

Remove dead code.

OK niallo@

#include's cleanup; ok joris@ niallo@.

knf and spacing, ok joris@

Produce more clear error message parsing date strings. ok joris@

* missing prototype for lookup()
* remove crufty VMS-specific code
* sprinkle some magic knf dust

use the date parsing code from date.y and fix timestamps on newly
created files so they match the values found in the corresponding
entries, otherwise all files appear as modified

ok joris

missing prototype for get_date();

from deraadt@

allow this to be compiled on its own for testing.

ok jfb@

alignment

more cleanup and knf

add missing prototypes for standard yacc functions and make yyerror()
accept a format with variable arguments
