libX: add new release / version info tags
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)
...
Note the library name and version information.
