Default to check-names for safety.

add <netinet/in.h> because it is needed for sockaddr_in.

make the default to not check names.

expose res_check for the benefit of mDNS.

Bring back binary compatibility with the previous version of the resolver.
There was no room to allocate 16 bytes for _rnd in the struct in the _LP64
case, so we dynamically allocate now. Also put the _rnd field last, so that
we are bitwise compatible too. Now of course we've run out of space, so
next time will need to perform more evil tricks to fit.

u_intN_t -> uintN_t

de-__P -- the hack is long since useless. Discussed with christos,
matt, kleink, others. Approved by christos.

Resolve conflicts.

Provide an ifdef so that we can define an old style _res if we need to.

Removr parameter names from __h_errno_set() function declaration.
Without this the vax port fails to compile the okheaders regression
test, because the "err" parameter name shadows a global variable.

PR/25707: Love: remove _LIBC from res_state as suggested, so that res_ninit
calls in userland don't trash memory.

Provide access to the 5 symbols the bind8 resolver libc did.

provide unconditional access to _res via __res_state(). This will abort
for multi-threaded programs.

resolve conflicts.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22270, verified by myself.

Remove variable names from prototypes.

transmission, not transmition.

branches: 1.19.2;
implement EDNS0 support, as EDNS0 support will be made mandatory for
IPv6 transport-ready resolvers/DNS servers. need careful configuration
when enable it. (default config is not affected).
see manpage for details.

XXX visible symbol __res_opt() is added, however, it is not supposed to be
called from outside, libc minor is not bumped.

define IPv6 library functions and structures, as defined in
RFC2292 and RFC2553.
define internal state structure for IPv6-transport resolver.

Commits for source code will follow.

revert part of previous; leave char lookups[4] in __res_state.
otherwise, complex versioning stuff will have to be performed so
that old binaries with a new libc.so don't barf

remove MAXDNSLUS and lookups[]; unnecessary with nsswitch

Make many of the new consts dependent on a new `__AUDIT__' flag, to avoid
breaking third party software. *sigh*

const poisoning.
