Fix a number of out of bound reads in DNS response parsing.
Originally from djm@. OK deraadt@ florian@ bluhm@

spelling fixes; from paul tagliamonte
any changes not taken noted on tech, but chiefly here i did not take the
cancelation - cancellation changes;

tolower(3) guarantees to return its argument unchanged if it's not
uppercase.
While here use the correct idiom of casting to unsigned char.

OK millert, farewell to ultrix deraadt

Remove old NeXT-specific cruft. From mmcc@

Wrap <resolv.h> so that internal calls go direct

ok millert@

Wrap <arpa/inet.h> and <arpa/nameser.h> so that calls go direct and the
symbols without underbar prefix are all weak

Replace HOST_NAME_MAX+1-1 with HOST_NAME_MAX. OK deraad@

Move to the <limits.h> universe.
review by millert, binary checking process with doug, concept with guenther

permit _ in the middle of a DNS name component

zap rcsid.
split functions off res_debug.c so that getnetnamadr.c does not pull it
all when it's used.

okay deraadt@, krw@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

We live in an ANSI C world. Remove lots of gratuitous #ifdef __STDC__ cruft.

Manual cleanup of remaining userland __P use (excluding packages maintained outside the tree)

Clean up some -Wall flowers.

Remove unused variables

constrain to MAXHOSTNAMELEN-1 not MAXDNAME, duh

constrain hostnames to MAXHOSTNAMELEN (again), and fix a typo

Integrate BIND 4.9.5 resolver and associated routines.

Includes the DNS aware getnetby*() routines and IPv6 support.

Fix RCS ids
Make sure everything uses {SYS,}LIBC_SCCS properly
