8a4599117b Don't include <sys/types.h> when it isn't used. 
This commit covers most of the ANSI library functions. Many others only
need <sys/types.h> because they use u_xxx.

064f007493 Added missing section numbers to a bunch of .Xr macros, or 
converted them into .Fn macros where appropriate.  Also fixed
up some minor formatting problems.

e1f4e80c88 Fixed a bunch of man page cross references that were 
in the main text of various man pages.

Thanks to Warner Losh for adding an option to manck to allow
it to scan the entire man page looking for bogus xrefs, instead
of just checking the SEE ALSO section.

78b0b234eb Correct a bunch of man page cross references and generally 
try and silence "manck".

ncurses, rpc, and some of the gnu stuff are still a big mess, however.

04936d2e08 Change phkmalloc so that the page directory is now floating and allocated 
via mmap() up around the shared library area.  Previously the directory
was allocated from space from it's own memory pool.  Because of the way it
was being extended on processes with large malloced data segments (ie: inn)
once the page directory was extended for some reason, it was not possible
to lower the heap size any more to return pages to the OS.
(If my understanding is correct, page directory expansion occurs at 4MB,
12MB, 20MB, 28MB, etc.)  I was seeing INN allocate a large amount of short
term memory, pushing it over the 28MB mark, and once it's transient demands
hit 28MB, it never freed it's pages and swap space again.)

I've been running this in my libc for about a month...

Also, seperate MALLOC_STATS from EXTRA_SANITY..  I found it useful to call
malloc_dump() from within INN from a ctlinnd command to see where the hell
all the memory was going.. :-)  I've left MALLOC_STATS enabled, as it has
no run-time or data storage cost.

7aa70c9e8e phkmalloc/2 
"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:

81df7b69ef ``phkmalloc'' 
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.

2bdca0d9f0 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.)

71e60921ff 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.
