82db4b9858 Replace consttime_bcmp/explicit_bzero by consttime_memequal/explicit_memset. 
consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

Passes amd64 release and i386/ALL, but I'm sure I missed some spots,
so please let me know.

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.

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

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.

The previous CTASSERT would never have been used because

unwanted effects from being just after the "static inline"
that appears when BZERO is defined.

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@.

d9210c2405 Add a new libquota library, which contains some blocks to build and/or 
parse quota plists; as well as a getfsquota() function to retrieve quotas
for a single id from a single filesystem (whatever filesystem this is:
a local quota-enabled fs or NFS). This is build on functions getufsquota()
(for local filesystems with UFS-like quotas) and getnfsquota();
which are also available to userland programs.
move functions from quota2_subr.c to libquota or libprop as appropriate,
and ajust in-tree quota tools.
move some declarations from kernel headers to either sys/quota.h or
quota/quota.h as appropriate. ufs/ufs/quota.h still installed because
it's needed by other installed ufs headers.
ufs/ufs/quota1.h still installed as a quick&dirty way to get a code
using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of
ufs/ufs/quota.h - old code won't compile without this change and this is
on purpose).
Discussed on tech-kern@ and tech-net@ (long thread, but not much about
libquota itself ...)

879d5dfb5e Fixes/improvements to RB-tree implementation:

   would represent lower (left) node, and positive - higher (right) node.
2. Add an argument (i.e. "context"), passed to comparison operators.
3. Change rb_tree_insert_node() to return a node - either inserted one or
   already existing one.
4. Amend the interface to manipulate the actual object, instead of the
   rb_node (in a similar way as Patricia-tree interface does).
5. Update all RB-tree users accordingly.

XXX: Perhaps rename rb.h to rbtree.h, since cleaning-up..

While kernel source code is supposed to use <machine/macros.h> via

can generate direct calls to memset() for structure initialization, so
the symbol must be provided.

fbd53556dc Wipe out the last vestiges of POOL_INIT with one swift stroke. In 
most cases, use a proper constructor.  For proplib, give a local
equivalent of POOL_INIT for the kernel object implementation.  This
way the code structure can be preserved, and a local link set is
not hazardous anyway (unless proplib is split to several modules,
but that'll be the day).

- Adjust the size of functions used to patch.
- Fix the jump offset of mcount call when patching functions.

0c9b734826 Fix crash where user was able to crash proplib with trying to internalize 
bad xml file with non-existing data type e.g. <number>.

Problem is that poi is not NULL even in case that we haven't find any match
in data type name. We need to check if poi->poi_tag is not NULL before
calling poi->poi_intern function which is non existing case NULL and will
cause crash.

d0b9e6c924 - remove bcmp(9), bcopy(9), and bzero(9) from libkern since <sys/systm.h> has 
macro which replace them with mem*() functions in #ifdef _KERNEL as noted
  in man pages
- move declarations of bcopy(3) and bzero(3) into <lib/libsa/stand.h>
  since they are still in libsa for some MD standalone sources
  (I guess all bcmp(3) in standalone sources have been replaced with memcmp(3)
   but they should be replaced with memcmp() anyway)

245ee9af71 Add local declarations of bcmp() and bzero() because libkern.h no longer 
provides those declarations.

It's possible that these can be removed later when we find out whether
these functions are actually needed in the kernel, but meanwhile, this
allows alpha, hp700 and the powerpc ports (who all build these as part
of libkern) to complete their builds.

81895b4b5d 0:0 is the adress x86emu_call pushes on the stack, so check for it here 
explicitly to stop processing again. As this is the start of the IDT,
normal code is not likely to override it.

89b1aba64b Fix three bugs in the instruction decoder: 
(1) Mode 5 for SIB uses EBP as base, not ESP.
(2) RM register mode 5 needs a segment override for SS when not using an
    immediate in 32bit mode.
(3) Same for mode 6 in 16bit mode.

23dc01f7e9 Properly handle empty data nodes (such as generated by Apple's 
plist editor). They are in the form of <data></data>, whereas the
original code path only checked for empty being <data/>.

This causes an assert to be triggered when trying to access the node's
content.
