ax_code_coverage.m4 dropped the @CODE_COVERAGE_RULES@ macro, so we need to switch to the latest recommendation from the m4 file. This requires updates to Makefile.am.

This commit adds the build directory to be ignored by git.
The motivation for adding this to .gitignore as opposed to
.git/info/exclude is that the CMake example in INSTALL.md uses build
as the name of the directory to be used by CMake. This will cause
git to report build as an untracked file.

strdup() is used in src/lib/ares_parse_a_reply.c and src/lib/ares_parse_aaaa_reply.c whereas allocated memory is freed using ares_free().

To prevent possible users having XSS issues due to intentionally malformed DNS replies, validate hostnames returned in responses and return EBADRESP if they are not valid.
It is not clear what legitimate issues this may cause at this point.

RFC1035 5.1 specifies some reserved characters and escaping sequences
that are allowed to be specified. Expand the list of reserved characters
and also escape non-printable characters using the \DDD format as
specified in the RFC.

The bug was generated because there was no check for the number
of items in the list and invalid memory was accesed when the list
was empty. There is a check for null after calling malloc but on
some systems it always returns a valid address for size equals 0.

ares_freeaddrinfo() was not checking for a Null ptr during cleanup of
an aborted query.
Once that was resolved it uncovered another possible issue with
multiple simultaneous underlying queries being outstanding and
possibly prematurely cleaning up the handle.

RANDOM_FILE was never defined by cmake, causing RC4 key generation to use the less secure rand() method.
Also, due to clashes with chain-building from other projects (e.g. curl) that may define RANDOM_FILE, this was renamed to CARES_RANDOM_FILE.
This is the proposed change for #396

There is too much inconsistency between platforms for arpa/nameser.h and arpa/nameser_compat.h for the way the current files are structured. Still load the respective system files but make our private nameser.h more forgiving.

NodeJS passes NULL for addr and 0 for addrlen parameters to ares_parse_ptr_reply(). On systems where malloc(0) returned NULL, this would cause the function to return ARES_ENOMEM, but the cleanup wasn't handled properly and would crash.
This patche fixes that bug, and also hardens ares_free_hostent() to not leak memory during cleanup.
Fixes: #392

Some systems may return either NULL or a valid pointer on malloc(0). c-ares should never call malloc(0) so lets return NULL so we're more likely to find an issue if it were to occur.
Buffered fread() reads 4096 bytes which is completely unnecessary and potentially may cause problems.
I discovered this on private linux configuration where custom /dev/urandom implementation has poor performance.

When c-ares is being built as static on Win32, CARES_STATICLIB must
be defined, but it wasn't being pulled in for the tools.
Fixes: #384

It appears that when building tests, it would hardcode enabling building
of the c-ares static library. This was probably due to Windows limitations
in symbol visibility.
This change will use the static library if it exists for tests, always.
Otherwise, it will only forcibly enable static libraries for tests on
Windows.

The fuzz test files were not being distributed. This doesn't appear to be
a regression, it looks like they have never been distributed.

Issue #377 suggested that CMake builds for iOS with c-ares were broken. This PR adds an automatic Travis build for iOS CMake.

It appears some outside projects were relying on macros in ares_dns.h, even though it doesn't appear that header was ever meant to be public. That said, we don't want to break external integrators so we should distribute this header again.

* remove: install-sh mkinstalldirs
They're generated when needed, no need to store in it.
* buildconf: remove custom logic with autoreconf
