On OS X, (u)int64_t is defined as (unsigned) long long int while on 74
bit Linux it is defined as (unsigned) long int.
Ensure the type matches when doing printf on all systems.
Several issues were encountered and fixed as explained bellow:
* missing link to dbug lib;
* user proper fprintf format specifier;
* ZERO_COND_INITIALIZER was using wrong toku_cond_t struct
initializer for first member of type pthread_cond_t and
not considering the TOKU_PTHREAD_DEBUG case which has
one extra struct member of type pfs_key_t;
* Remove likely(!opt_debug_sync_timeout), argument is
declared extern and not available to Toku;
* pthread_mutex_timedlock() is not available in pthreads
for Mac, as it's not part of the POSIX pthreads spec.
The encompassing event_t::wait(ms) methods are unused,
thus have been removed;
