IIvecandMarco Costalba aa88261a8f Revert to old time management (#1351) 
As many users reported some problems with new time management,
and recent tests on longer time controls

http://tests.stockfishchess.org/tests/view/5a462f4d0ebc590ccbb8c37a

are even little in favor of old time management, this revert seems as a logical step.

IIvecandMarco Costalba 287e2e2f74 Fix premature using of all available time in x/y TC 
In x/y time controls there was a theoretical possibility
to use all available time few moves before the clock will
be updated with new time. This patch fixes that issue.

Tested at 60/15 time control:

Total: 113963 W: 20008 L: 20042 D: 73913

The test was done without adjudication rules!

This time management handles base time and movestogo cases separatelly. One can test one case without affecting the other. Also, increment usage can be tested separately without (necessarily) affecting sudden death or x moves in y seconds performance.

On stable machines there are no time losses on 0.1+0.001 time control (tested on i7 + Windows 10 platform).
