bc830a1980 Do not use the builtins for the mem* functions on vax, the compiler gets 
confused with the static inline functions vax uses.

0f95ec4fd5 ESP output was drawing down the entropy pool at a ferocious rate, a 
particular problem on hosts with only wireless interfaces that are
definitely not safe to use as entropy sources.

Add arc4randbytes() which hands out bytes from the same source used
by arc4random().  This is intended to be a _temporary_ interface
until we can design and implement a better general PRNG interface
that is decoupled from the entropy-pool implementation.

Modify key_randomfill() (used only for initialization vectors on
SA creation and via key_sa_stir_iv(), which does not "stir",
despite its name) to use arc4randbytes() instead of pulling bits
directly from the entropy pool.  It is my hope that this change
will pose minimal integration problems for the KAME folks as the
random-pool interface is *already* different between each BSD
variant; this just simplifies the NetBSD case and solves a
fairly serious problem.

Note that it is generally considered acceptable cryptographic
practice to use a fast stream cipher to generate IVs for encryption
with stronger block ciphers.  For example, the use of "non-Approved"
PRNGs to generate IVs for "Approved" block ciphers is explicitly
sanctioned by FIPS 140-2.

26737526db Add strstr() to libkern. For now, it's only used in i386 (for processor 
identification).

3f5fba68de Do not try to use "__builtin_ffs" on vax, ffs is an instruction already. 
Maybe possible to teach gcc to use it?

5ed948ecea The kernel is now built with -ffreestanding, so GCC built-ins are 
disabled.  Explicitly re-enable some that we want to use, namely:

* memcpy() -> __builtin_memcpy()
* memcmp() -> __builtin_memcmp()
* memset() -> __builtin_memset()

* strcpy() -> __builtin_strcpy()
* strcmp() -> __builtin_strcmp()
* strlen() -> __builtin_strlen()

We might also consider some others for GCC 3.x.

5439e1a9ff Put the prototypes for bcmp() and bzero() back (ifdef _STANDALONE) so that 
libsa builds again.

707b3d59b1 __predict_true() the expressions passed to the assert family, so

4634c0e3d4 libkern just got an inet_addr(), but it won't compile, no prototype. Cleanup... 
* Add prototype to libkern.h.
* Remove the almost-identical-copy from libsa/net.[ch].
* Change its type back to the (wrong, but harmless) historical one. (u_long)
* Kill the XXX local prototype in nfs_bootparam.c

6ac982f2a0 mark prototypes for static inline functions as possibly unused (with 
__attribute__ ((unused))), to avoid generating warnings when compiling
without optimization but with most ports' default warning flags.

d867ed50cc add strchr() to libkern. strchr.c copied from libc's "index.c", but with 
appropriate definitions so that it'll build strchr(), and so that it builds
correctly in libkern (needed to #define NULL).

bdbfa48c0b Add machine-independent assertion-checking support. macros are: 
assert()	which always does assertion checking
			unless "NDEBUG" is defined.

	KASSERT()	which does assertion checking if DIAGNOSTIC
			is defined.

	KDASSERT()	which does assertion checking if DEBUG is
			define.  This macro exists for compatibility
			with existing ports' assertion checking macros.
			(Assertion checking is not typically an
			"expensive" operation, and DIAGNOSTIC should be
			used for inexpensive consistency checks.)

a0a7429482 lots of changes: prototype migration, move lots of variables, definitions, 
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.
