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

Change Intel PT and BTS to pass up the length and the instruction
bytes of the decoded or sampled instruction in the perf sample.
The decoder already knows this information, we just need to pass it
up. Since it is only a couple of movs it is not very expensive.
Handle instruction cache too. Make sure ilen is always initialized.
Used in the next patch.

Tidy instruction buffer size usage in preparation for copying the
instruction bytes onto samples.
The instruction buffer is presently used for debugging, so rename its
size macro from INTEL_PT_INSN_DBG_BUF_SZ to INTEL_PT_INSN_BUF_SZ, and
use it everywhere.
Note that the maximum instruction size is 15 which is a less efficient size
to copy than 16, which is why a separate buffer size is used.
