avoid memcpy(malloc(0), ..., 0), which is not portable.

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;

branches: 1.11.22; 1.11.24;
Put a common subq pointer in the query struct, rather than one in each
element of the union.

ok gilles@ millert@ krw@

remove bogus includes of err.h

Wrap <asr.h> so internal calls go direct and all the symbols are weak

Hide all unnecessary asr / resolver related API with _ prefixes.
direction & ok guenther

Make the asr API public. Install asr.h to /usr/include.h and manpages.
Include tweaks suggested by mpi@

ok deraadt@

Cleanup and simplify the API to be exposed. Use better names for
structures, functions and defines.

discussed with and ok deraadt@ guenther@

Make some symbols static and prefix all visible symbols with asr_
to prevent collisions with third-party programs.

suggested by sthen@, ok theo@

Do not take external buffers for storing DNS responses in the internal
async API. That is actually useless and it makes the code more
complicated. The required buffers are always allocated when needed.

knf

getrrsetyname() only uses ERRSET_* and is not supposed to set errno.
make sure to save and restore errno properly.

Import asr, an experimental async resolver implementation.
The idea is to eventually replace the existing resolver with
something better. Time to start working on it in tree.
