Doubled the performance of getenv()/__findenv() by rewriting it to not

use strncmp()..

"zero' and 'junk' options to help find and diagnose malloc abuse.
EXTRA_SANITY defaults "junk" to on.
Don't dump the internal state, unless EXTRA_SANITY.
General code cleanup.
Error messages cleaned up a bit, more checking earlier.
EXTRA_SANITY is default at this time (just in case).
Performance (without EXTRA_SANITY) is better, beats gnumalloc in
both time & space most of the time:

SANITY is not an option anymore. (!!)

Performance is comparable to gnumalloc if you have sufficient RAM, and
it screams around it if you don't.
Compiled with "EXTRA_SANITY" until further notice.
see malloc.3 for more details.

Similar changes like in strtol, all this family is VERY broken

in 8bit environment (isalpha at the end of digits)

strtol and atoi VERY broken in 8bit chars locale, i.e. if you pass something
...
like 38400<any 8bit char, isalpha> it not detect this stuff and
produce very big number instead. Fixed by operating with unsigned char
and checking for isascii. (secure/telnetd hits by it f.e.)

Fix a missing _hash() to prevent namespace pollution with the db/hash routines.
...
Grrr. If the dbhash routines weren't grossly overengineered I wouldn't
even need to do this! :-(
Also now export the hash_stats routine. Manpage coming RSN - I promise.

Add the strhash family of routines. They provide a number of features
...
that the db/hash functions don't, and they're much simpler to use for
low-overhead string hashing.

Don't attempt to lstat() the POSIXLY invalid empty pathname.

realpath() still accepts "" as an arg and converts it to a canonical
pathname for the current directory.

or depend on <stdio.h> bogusly including it.

First crack at making libc work with the new make macros. It compiles on
...
my machine, and a simple static (genassym) and shared (sysctl) executable
both work. Still to be done: RPCand YP merge.
