- Disables warnings for no-braced-scalar-init which shows up for ATOMIC_VAR_INIT.
- Fixes compile warnings, mostly "moving a temporary objects prevents
copy elision" (-Wpessimizing-move) and unused variables.
- Adds some necessary fields to make the sample compile after having
build the core library.
1) Added macro EASY_CONST_NAME(name) to make possible to force EasyProfiler think that given block name is const and not changed during application execution (this rely to compile-time strings saved into a run-time variable);
2) Starting from now, EasyProfiler will not store partially finished frames - first, this means that profiler enabled during frame execution will skip all blocks from this frame, and second, this means that when dumping profiled information profiler will wait until all frames finish before dumping blocks.
* (Core) Context switch events also register threads for current process;
* (Core) Writing process id into output file (old files still could be opened);
