b7781e8faa search_pv: spaces inflate
It seems easier to understand, at least to me.

Hopefully no functional change.

a230dc1404 Split transposition table lookup in a separate function
This slims down the code and is a prerequisite for
future patches.

61f41a057d 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.

dad9a1eca7 RootMoveList: inline trivial accessors
Although not performance critical, trivial
accessors can be inlined without any harm.

731a9f3806 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.

bd3fd6501b scan_for_easy_move: we don't need a loop here
Moves are already sorted, so just consider the best
and the second one.

Some trailing whitespace remove noise crept in due
to my editor removes it before to save.

973eb543a4 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.

6ef44d4c4e Finally remove UCIInputParser class altogether
Class UCIInputParser is now a typedef of a std::istringstream,
this greatly simplifies the code, especially the many conversions
from string to integer are now handled automatically by the
stream instead of relying on a chunk of C-style atoi() calls.
