1239c2bb08 Publish explicit_memset and consttime_memequal in userland libc. 
Remove the double-underscore from the userland versions, and do the
weak alias dance instead, now that these are public parts of libc.

As discussed on tech-userlevel:

https://mail-index.netbsd.org/tech-userlevel/2013/06/24/msg007843.html

cc79193075 Fix sense of consttime_memequal and update all callers. 
Now it returns true (nonzero) to mean equal and false (zero) to mean
inequal, as the name suggests.

c7dafd4acd Do not use isalpha here, since we explicitly only support the Portable 
Character Set as base and in theory a locale could define a ASCII
control character as letter, resulting in negations. Also avoid isdigit
here to give the compiler a better chance of deciding whether an
unsigned compare or a jump table is a better option, both are very
likely better choices than the memory indirection.

2fa47ecfcb Lint seems to prefer that we cast via (void*) and not directly to 
(u_char*), so follow suit.

2953114330 Change CTASSERT to __CTASSERT (the spelling used in <sys/cdefs.h>), 
include <sys/cdefs.h> so that it will be defined,
and move it to a better place.

The previous CTASSERT would never have been used because
of the ifdef.  If it had been used, it would have had
unwanted effects from being just after the "static inline"
that appears when BZERO is defined.

Also move the __RCSID to a more conventional location.

59b296daa7 Change the syscall API for quotas over to the new non-proplib one. 
- struct vfs_quotactl_args -> struct quotactl_args
   - add sys/stdint.h to sys/quotactl.h for clean userland build
   - install sys/quotactl.h in /usr/include
   - update set lists for same
   - add new marshalling code in libquota
   - add new unmarshalling code in vfs_syscalls.c
   - discard proplib interpreter code in vfs_quotactl.c
   - add dispatching code for the 14 quotactl ops in vfs_quotactl.c
   - mark the proplib quotactl syscall obsolete
   - add a new syscall number for the new quotactl syscall
   - change the name of the syscall to __quotactl()
   - remove the decl of the old quotactl from quota/quotaprop.h
   - add a decl of the new quotactl to sys/quotactl.h
   - update the libc build
   - update ktruss
   - remove proplib marshalling code from libquota
   - update copy of syscall table in gdb ppc sources
   - hack rumphijack to accomodate new quotactl name (as I recall,
     pooka wanted such a name change to simplify something, but I
     don't really see what/how)

This change appears to require a kernel version bump for rumpish
reasons.

e8bec33be1 Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions 
again. This was changed in sys/socket.h r1.51 to work around fallout
from the IPv6 aux data migration. It broke the historic ABI on some
platforms. This commit restores compatibility for netbsd32 code on such
platforms and provides a template for future changes to the CMSG_*
alignment. Revert PCC/Clang workarounds in postfix and tmux.

c60360c18d Reshuffle decls among the quota headers so everything is in the place 
it should be:
   - stuff for the proplib interface goes in <quota/quotaprop.h>
   - stuff for userlevel only goes in <quota/quota.h>
   - stuff shared between user and kernel goes in <sys/quota.h>

Note that <quota/quota.h> and <quota/quotaprop.h> are expected to be
moved or removed later on... one thing at a time.

Update include directives in other files as needed.
