- Portability fix for systems where socklen_t is bigger than int.
- Fix for malicious optimisation of memcpy in test suite, which
causes failure with gcc-4.1.9 -O3. See Debian bug #772718.
- Fix TCP async connect handling. The bug is hidden on Linux and on most
systems where the nameserver is on localhost. If it is not hidden,
adns's TCP support is broken unless adns_if_noautosys is used.
- Fix addr queries (including subqueries, ie including deferencing MX
lookups etc.) not to crash when one of the address queries returns
tempfail. Also, do not return a spurious pointer to the application
when one of the address queries returns a permanent error (although,
the application almost certainly won't use this pointer because the
associated count is zero).
- adnsresfilter: Fix addrtextbuf buffer size. This is not actually a
problem in real compiled code but should be corrected.
- Properly include harness.h in adnstest.c in regress/. Suppresses
a couple of compiler warnings (implicit declaration of Texit, etc.)
