e0ac190e1e Provide explicit LC_C_LOCALE accessor and drop the various NULL checks. 
Provide LC_GLOBAL_LOCALE in a way that works with all locale functions.
Merge constant data used by the initial global locale and the C locale.
Drop function call layer for _current_locale() and directly return the
locale reference, not a pointer to it. Use protected access for global
variables, so that libc references can avoid the GOT overhead.

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.

magnitude slower than the existing libc version.

44d1b59f26 Make this work on all ARMs but keep the armv6 optimizations. It as fast as 
the existing strlen for small string and once strings are 8 bytes or more in
length it starts getting significantly faster.  For really long strings,
compared to the existing strlen, this uses about 1/2 of the cycles for the
non-armv6 version and about 1/3 of the cycles for the armv6 version.

8588929dc5 Add "consttime_bcmp" and "explicit_bzero" functions for both kernel 
abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.

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.

   - 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

   - 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.

afca4e3b49 Fix an implementation inconsistency with the prop_*_send_syscall() and 
prop_*_recv_syscall() functions from proplib(3). They now share the
same logic as the one from prop_*_send_ioctl() functions:
- returns an int
- 0 indicates "no error", otherwise returns the error number (and
set errno)

Many consumers of the prop_*_{ioctl, syscall} expect errno to be set
on error and use err() to display the error message. As such, ensures that
errno gets set before returning from these functions.

prop_*_send_syscall() functions returned a boolean, and now return an int.
Fix all call sites to use the new paradigm (only quota2 is affected in src).

As the prop_*_{send,recv}_syscall() API appeared in -current and is only
used by the recent quota2 code, I am not bumping the lib. The API change
only affects the prop_*_send_syscall() function (recv_syscall()s were
already used correctly), so ensure you are not mixing "old" -current
quota binaries with a new proplib(3) (or the other way around). This
change will be announced via a HEADS-UP and UPDATING.

Does not affect the kernel part of proplib.

Document the correct API in prop_array(3) and prop_dictionary(3).

Thanks to Francois Tigeot for noticing the API inconsistency and
reporting it on tech-kern@.

ok bouyer@.

4c44c335c5 loongson2f support: 
- Add some loongson2 definitions to cpuregs.h, from OpenBSD
- Make sure that the at register is useable before every jump register
  instruction (exept when register is k0 or k1) because -mfix-loongson2f-btb
  needs the at register for its workaround
- add code to mips_fixup.c to handle the instructions added by
  -mfix-loongson2f-btb
- Add a ls2-specific tlb miss handler: it doesn't have separate handler
  for the xtlbmiss exeption.
- Fixes for some #ifdef MIPS3_LOONGSON2 assembly code (using the wrong
  register)
