TranspositionTable: add first_entry() helper

Add simple debug hit rate counter
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.

RootMoveList: inline trivial accessors

RootMoveList sorting: be compatible with std::sort
sort() and sort_multipv() are almost the same, so
use only one implementation.
Also introduce the natural RootMove::operator<() to
compare the moves instead of compare_root_moves(),
this will allow to use std::sort instead of our
home grown bubble-sort.

Fix a couple of bugs (fallout from previous patches)
After testing and comparing output with standard Glaurung
a couple of issues arised.
A default value was wrong and init_uci_options() missed a couple
of stringify() calls. Also storing bool values as "false" and "true"
needs some care.

Finally remove UCIInputParser class altogether
