Tracepoint arguments are now reconstructed when retrieving next trace
entry (possible from multiple buffers). Similarly to previous patches,
the code is directly copied from the spdk_trace app.

Added a definition of a parsed trace entry and a function allowing for
iterating over these objects. The difference between a parsed and a
regular trace entry is that it includes more information gathered while
processing the trace file (e.g. lcore, object statistics) and provides a
contigous buffer for trace arguments.
For now, only lcore and the pointer to the actual trace entry are
filled. Tracepoint arguments and object statistics will be added in
subsequent patches.

The trace file is now parsed and the entries are put in a map, sorted by
their timestamps. The code is directly copied from the spdk_trace app,
with very little modifications.

Copied code responsible for mapping/unmapping the trace file. The
only modifications were related with tying it to the spdk_trace_parser
object.

This library will provide functions that parse traces recorded by an
SPDK application. This includes merging traces from multiple cores,
sorting them by their timestamp and constructing trace entries spanning
across multiple buffers. All of these tasks are currently implemented
in the spdk_trace app, so most of its code will be moved here (this is
the reason for using C++).
The motivation for extracting this code to a library is to be able to
use it from places other than the spdk_trace app, specifically the
`scripts/bpf/trace.py` script.
The main reason for creating a separate library instead of extending
libtrace is to avoid pulling in all of its dependencies. ISA-L is the
most problematic, as we only build it as a static library, which makes
it impossible to use with dlopen (making it unusable in scripts).
