FreeBSD 12 supports 'pthread_rwlock_tryrdlock' without 'pthread'
library. Let's add check for more rare function.
OTOH, Travis-CI environment supports 'pthread_rwlockattr_destroy',
but does not support 'pthread_rwlock_tryrdlock' without 'pthread'.
So, both checks needed.

On my laptop, pthread_create() is always available without -lpthread, but
when I use -fsanitize=address, -lpthread is required to pull in other
threading functions such as pthread_rwlock_tryrdlock(). Thus, with
-fsanitize=address I have to manually add -lpthread to link commands one
way or another. This commit avoids that problem by checking for a
function that is sometimes only available in -lpthread.

This commit renames HAVE_PYTHON to HAVE_PYTHON2 and PYTHON to PYTHON2
and adds HAVE_PYTHON and PYTHON with a different semantics:
- If PYTHON environment variable is set, use it as PYTHON
- If a python2 interpreter is available, PYTHON became the python2 interpreter
- If a python3 interpreter is available, PYTHON became the python3 interpreter
PYTHON is only used to run the python scripts needed by the build system
NOTE:
Since currently most of the utilities and bugtool doesn't support Python3,
they're installed only if python2 is available. This will be fixed in later
commits.

This patch is a simple implementation for the proposal discussed in
https://mail.openvswitch.org/pipermail/ovs-dev/2017-August/337038.html and
https://mail.openvswitch.org/pipermail/ovs-dev/2017-October/340013.html.
It enables ovs-vswitchd and other utilities to use DNS names when specifying
OpenFlow and OVSDB remotes.
Below are some of the features and limitations of this patch:
- Resolving is asynchornous in daemon context, avoiding blocking main loop;
- Resolving is synchronous in general utility context;
- Both IPv4 and IPv6 are supported;
- The resolving API is thread-safe;
- Depends on the unbound library;
- When multiple ip addresses are returned, only the first one is used;
- /etc/nsswitch.conf isn't respected as unbound library doesn't look at it;
- For async-resolving, caller need to retry later; there is no callback.

adds support.

Since commit f12e09b7b2e5 ("libopenvswitch: Rename to libfoo-X.Y."), the
CURRENT libtool number is no longer derived from the OVS MINOR (from
vMAJOR.MINOR.MICRO) version, so it can be reset to 0.
Developers should attempt to avoid introducing ABI-breaking changes
within a particular OVS-X.Y release series. Occasionally due to the
nature of a particular bug, this is not possible. In such a case,
developers must update the libtool CURRENT version to indicate this
breakage to library users.
In most OVS library releases, this is expected to remain 0.

This commit uses the $PACKAGE_VERSION automake variable to construct a
release and version info combination which sets the library name to be:
libfoo-$(OVS_MAJOR_VERSION).so.$(OVS_MINOR_VERSION).0.$(OVS_MICRO_VERSION)
where formerly, it was always:
libfoo.so.1.0.0
This allows releases of Open vSwitch libraries to reflect which specific
versions they came with, and sets up a psuedo ABI-versioning scheme. In
this fashion, future releases of Open vSwitch could be installed
alongside older releases, allowing 3rd party utilities linked against
previous versions to continue to function.
ex:
$ ldd /path/to/utility
linux-vdso.so.1 (0x00007ffe92cf6000)
libopenvswitch-2.so.6 => /lib64/libopenvswitch-2.so.6 (0x00007f733b7a3000)
libssl.so.10 => /lib64/libssl.so.10 (0x00007f733b530000)

Add configuration option for enabling or disabling linking with

option is handled as follows:
- no option: use libcapng if it's present
--disable-libcapng: do not use libcapng
--enable-libcapng: do use libcapng and fail configuration if
it's missing
On Linux, not linking with libcapng makes all OVS daemons fail when
