Use type-specific inline function imax() instead of deprecated macro MAX().

Prodded by: bde

Fix build by defining MAX() macro here.

Sync. printf() of libstand(3) with sys/kern/subr_prf.c.

CVS r1.94 jhb:
Cast the integer read as the first argument for %b to an unsigned integer
so it's value is not sign extended when assigned to the uintmax_t variable
used internally by printf. For example, if bit 31 is set in the cpuid
feature word, then %b would print out the initial value as a 16 character
hexadecimal value. Now it only prints out an 8 character value.

CVS r1.109 njl:
Add support for 'h' and 'hh' modifiers for printf(9).

CVS r1.117 phk:
If we ignore an unknown % sequence, we must stop interpreting the remaining
% arguments because the varargs are now out of sync and there is a risk that
we might for instance dereference an integer in a %s argument.

SVN r209836 jkim:
Implement optional 'precision' for numbers. Previously, it was parsed but
ignored. Some third-party modules (e.g., APCICA) prefer this format over
zero padding flag '0'.

Obey signedness flag in %z case.

MFC after: 2 months

Remove California Regent's clause 3, per letter

Implement printf 'X' conversion for both libstand and kernel.

Sync up with kern/subr_prf.c. This adds %ll, %j, %q, %z, etc.

Use the standardized CHAR_BIT constant instead of NBBY in userland.

Remove 'register' keyword.

Add __FBSDID()s to libstand

Tidy up some loose ends. nullfs_read/write were returning the wrong value.
Fix some ctype problems - isascii() caused a warning if fed an unsigned
char - it's always > 0 and libstand is compiled with -Wall.
Missing prototype/include in printf.c

$Id$ -> $FreeBSD$

Add:
assert()
setjmp()/longjmp()
vsprintf()

This is libstand; a support library for standalone executables (eg. bootstrap
modules).
Obtained from: NetBSD, with some architectural changes and many additions.
