Character Set as base and in theory a locale could define a ASCII

Migrate one last leftover bit (used only by the kernel now) to

sys/ufs/ufs and remove the old quota headers and no-longer-used shared
code. Ok by releng.

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.

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.

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.
