Summary:
Annotate all of the logging functions to inform the compiler that these
use printf-style formatting arguments. This allows the compiler to emit
warnings if the format arguments are incorrect.
This also fixes many problems reported now that format string checking
is enabled. Many of these are simply mix-ups in the argument type (e.g,
int vs uint64_t), but in several cases the wrong number of arguments
were being passed in which can cause the code to crash.
The primary motivation for this was to fix the log message in
`DBImpl::SwitchMemtable()` which caused a segfault due to an extra %s
format parameter with no argument supplied.

Summary:
db_stress was already capable running transactions by setting use_txn. Running it under stress showed a couple of problems fixed in this patch.
- The uncommitted transaction must be either rolled back or commit after recovery.
- Current implementation of WritePrepared transaction cannot handle cf drop before crash. Clarified that in the comments and added safety checks. When running with use_txn, clear_column_family_one_in must be set to 0.

Move DuplicateDetector and SetComparator to its own header file in util. It would also address a complaint in the unity test.
