tools lib traceevent: Add version for traceevent shared object
Adding version support for libtraceevent.so object.
Using the existing EVENT_PARSE_VERSION variable to construct
the .so object version string, which now consists of:
$(EP_VERSION).$(EP_PATCHLEVEL).$(EP_EXTRAVERSION)
Looks like it was created for this purpose anyway.
The build will now produce following traeceevent libraries:
$ ll libtraceevent*
libtraceevent.a
libtraceevent.so -> libtraceevent.so.1.1.0
libtraceevent.so.1 -> libtraceevent.so.1.1.0
libtraceevent.so.1.1.0
Also the install target will carry them:
$ make DESTDIR=/tmp/krava prefix=/usr install
INSTALL trace_plugins
INSTALL libtraceevent.a
INSTALL libtraceevent.so.1.1.0
$ find /tmp/krava/ | xargs ls -l
...
/tmp/krava/usr/lib64:
total 572
libtraceevent.a
libtraceevent.so -> libtraceevent.so.1.1.0
libtraceevent.so.1 -> libtraceevent.so.1.1.0
libtraceevent.so.1.1.0
...
