strdup()) rather than pointing it at something that's free()d
(via freeaddrinfo(res)) before the function returns.
I appreciate that this is an API change, but it's the only way
(AFAIK) of doing this without breaking existing code that uses
rcmd{,_af}().
Pointed out by: phkmalloc
management involving rcmd_af(), getaddrinfo(), freeaddrinfo(), etc.
We set *ahost to point to ai->canonname; and later free the ai-> stuff
and still leave the old pointers in *ahost to the freed data.
Perhaps the best way to deal with this is a static buffer or a static
strdup() that is freed on the next iteration or something. This gives
me headaches just thinking about this.
The new 'AJ' default for malloc() tripped this up.
of the processing of the recursion, "scan" would be pointing to O_CH
(or O_QUEST), which would then be interpreted as being the end character
for altoffset().
We avoid this by properly increasing scan before leaving the switch.
Without this, something like (a?b?)?cc would result in a g->moffset of
1 instead of 2.
I added a case to the soon-to-be-imported regex(3) test code to catch
this error.
string may be found (from the beginning of the pattern), the point
at which must is found minus that offset may actually point to some
place before the start of the text.
In that case, make start = start.
Alternatively, this could be tested for in the preceding if, but it
did not occur to me. :-)

use a CHAR_MIN-based array, like elsewhere in the code.
Remove a number of unused variables (some due to the above change, one
that was left after a number of optimizing steps through the source).

remove (comment out) functions defined or depricated elsewhere:
bsearch, lfind, lsearch, insque, remque
change hcreate to take a size_t rather than uint (essentially the same)
since hcreate/hdestroy are now in <search.h>, remove private search.h
in lib/libc/db/hash/
add $FreeBSD tags to hsearch.c
- permit numeric scopeid, be more careful about buffer size

when code tries to examine the returned host name, it dereferences a null
