* Detect empty entries.
* Parse the trace entries using the struct python library
* fix realloc accounting
* multiple fixes in chattyparser

We use two mappings to reduce waiting time during growth of the trace file.

chattymalloc is now more deterministic through binary logging.
It seems we aren't loosing traces anymore and need less space.
Each thread has it private tracebuffer, which gets passed to write()
for each function call.

chattyparser now parses binary traces while producing a plain text representation.
It can also detect mostly all possible false sharing through traking the
cached lines for all life allocations.
Only allocations passed between threads are not tracked correctly as well
as thread termination.

This reverts commit 0978c0cbbcdca5394b2a0aeeab0771939021fd15.
