We have much better control over visibility now, so we don't need to
pollute the headers with cruft.

_resolv_set_nameservers_for_net() so far did not update the search
paths, unless the servers changed as well.

Not a public header file except in NetBSD, where it came from. Even
OpenBSD doesn't have it.

* changes:
Remove nonexported _ns_flagdata from public header.
Add platform specific version tags.
Add __INTRODUCED_IN_FUTURE for unreleased APIs.
Add versioning information to symbols.
Fix the resolver information returned by
android_net_res_stats_get_info_for_net,
erroneously included MAXDNSRCH empty results if no search path was set.

android_net_res_stats_get_info_for_net returns the current name servers, search
domains, parameters and stats for the given network ID.
android_net_res_stats_aggregate provides statistics such as errors counts from
the raw stats data reported by android_net_res_stats_get_info_for_net.
android_net_res_stats_get_usable_servers uses the data returned by
android_net_res_stats_aggregate to determine which of the servers are
considered valid or broken by the resolver.

Instead of keeping a sentinel after nameservers[], nsaddrinfo[] and
nstats[], store the server count in the structure, freeing up memory and
eliminating the need to enumerate the server count every time
_resolv_is_nameservers_equal_locked() is invoked.
Also increase MAXNS from 3 to 4.

This was fixed upstream years ago. While we're here, let's switch to the
OpenBSD copy (because that's our majority upstream BSD, not because they
found and fixed this bug first).

Collect statistics about DNS query success state and delay. Ignore
servers that have been tried at least five times and have a success rate
of < 0.25. Retry these servers once every 180s.

The DNS search string contains zeros as domain separator. The resolver
code erroneously used strlcpy(), which resulted in only the first domain
to be copied. The code uses pointers into this string to access the
individual domains. Since the structure is zero-initialized, this bug only
resulted in zero-length domains instead of accessing unitialized memory.

Our FORTIFY _chk functions' implementations were very repetitive and verbose
but not very helpful. We'd also screwed up and put the SSIZE_MAX checks where
they would never fire unless you actually had a buffer as large as half your
address space, which probably doesn't happen very often.
Factor out the duplication and take the opportunity to actually show details
like how big the overrun buffer was, or by how much it was overrun.
Also remove the obsolete FORTIFY event logging.
Also remove the unused __libc_fatal_no_abort.
This change doesn't improve the diagnostics from the optimized assembler
implementations.

In the serialized output from netd, the strings come first. Some code
assumes -- reasonably enough -- that it can do unaligned reads of pointers,
so we need to ensure alignment after all the strings.

Group network context elements in to a single struct and
add a version of android_getaddrinfofornet() that accepts it.
The introduction of UID-based routing means that the UID is an
integral part of the network context when evaluating connectivity,
sorting addresses, etc.
Also, introduce a distinction between DNS netids/marks and those
expected to be used by the application. This can be important
when the network an application is using is not the same as the
network on which DNS queries will be issued.
Additionally, de-duplicate the UDP connect logic (collapse both
_test_connect() and _find_src_addr() into just the latter).

Interestingly, this mostly involves cleaning up our implementation of
various <string.h> functions.

The code now compiles with all combinations of DEBUG and
DEBUG_DATA except DEBUG_DATA=1, DEBUG=0, which is unsupported.
