Fix setenv/getenv/unsetenv to be OpenGroup compliant:
* libc/include/stdlib.h (unsetenv, _unsetenv_r): Redefine with integer
return types.
* libc/stdlib/getenv_r.c (_findenv_r): Do no special processing with
names that contain equal chars.
* libc/stdlib/setenv.c: Redefine _unsetenv_r as returning int.
* libc/stdlib/setenv_r.c (_setenv_r): Return -1 and set errno to
EINVAL if name contains an equal sign. Do not remove any equal signs
from the value.
(_unsetenv_r): Modified to return int. Return -1 and set EINVAL
if name contains equal sign. Return -1 if no variable(s) were found
and return 0 otherwise.
* libc/include/machine/setjmp-dj.h: With DJ Delorie's permission,
changed the copyright information to allow free modification of the
file with no reference to "copying.dj".
* libc/include/sys/stat-dj.h: Ditto.
* libc/machine/i386/setjmp.S: Ditto.
* libc/sys/h8300hms/sys/file.h: Ditto.
* libc/sys/sysmec/access.c: Ditto.
* libc/sys/sysnecv850/access.c: Ditto.
* libc/stdio/mktemp.c: Fixed typo for the word copyright.
* libc/stdlib/getenv_r.c: Ditto.
* libc/stdlib/putenv_r.c: Ditto.
* libc/stdlib/setenv_r.c: Ditto.
* libc/stdlib/getenv.c: Removed DJ reference since any possible
modifications will now be in the _r version of this file.
* libc/stdlib/putenv.c: Ditto.
* libc/stdlib/setenv.c: Ditto.
* libc/sys/go32/copying.dj: Removed DJ's address which is no longer
valid. Added a reference to DJ's web page that contains his address.
* libc/sys/go32/*.s: Removed references to DJ's old address.
* libc/sys/go32/*.c: Ditto.
* libc/sys/go32/*.h: Ditto.
* libc/sys/go32/*.S: Ditto.
* libc/sys/go32/sys/*.h: Ditto.
