Sharing map groups within all process threads. This way
there's only one copy of mmap info and it's reachale
from any thread within the process.

Adding automated test for memory maps lookup within
multiple machines threads.
The test creates 4 threads and separated memory maps.
It checks that we could use thread__find_addr_map
function with thread object based on TID to find
memory maps.

Moving towards sharing map groups within a process threads.
Because of this we need the map groups to be dynamically
allocated. No other functional change is intended in here.

Forcing the code to always search thread by pid/tid pair.
The PID value will be needed in future to determine
the process thread leader for map groups sharing.

. Add support for the new DWARF unwinder library in elfutils (Jiri Olsa)
. Fix build race in the generation of bison files (Jiri Olsa)
. Further streamline the feature detection display, trimming it a bit to
show just the libraries detected, using VF=1 gets a more verbose output

The trace_do_page_fault function trigger tracepoint
and then handles the actual page fault.
This could lead to error if the tracepoint caused page
fault. The original cr2 value gets lost and the original
page fault handler kills current process with SIGSEGV.
This happens if you record page
