This code is platform specific and has nothing to
do with TT class, so move to misc.cpp
This patch is a prerequisite to use extend prefetch use
also to other hash tables apart from Transposition Table.
No functional change.

Centralize in a single object all the global resources
management and avoid a bunch of sparse exit() calls.
This is more reliable and clean and more stick to C++ coding
practices.

Other two debug utilities to compute filter rate.
Usage is:
dbg_before(); // counts passages from this point
if(..) // complex code stuff you want to audit
return/continue
if(...)
.....
dbg_after(); // counts passages from this point
Then somewhere in the code, normally in poll() add
dbg_print_hit_rate() and you will see the filter rate
of your code under auditing.

Like dbg_hit_on(x) but first filter out events and
only when condition 'c' is true the hit counter
is tested with 'x'.

Add a very simple debug framework to
measure the hit rate of a given condition.
Simply insert macro
dbg_hit_on(x);
Anywhere you want to compute hit rate of condition x
and then call, as example in poll(), function
dbg_print_hit_rate() to print current results.
