Adding some code for the evaluation of prepared statements
Variable mysql-stmt_multiplexing is introduced too, but not active

A new Query_Processor_Output (qpo) is allocated for every query. Allocation is now done once per session, thus speeding up execution time under memory profiler
sysbench starts running
So far, single thread sysbench is working. Multi-threaded and resume from broken connections is still not working. It means it still needs a lot of changes.
Introduced classes: * stmt_execute_metadata_t * MySQL_STMTs_meta
* converted MySQL_Authentication to use unsorted_map instead of btree_map * Query_Cache now uses pointers to KV_BtreeArray * removed some unnecesary headers
* fixed multiplexing * fixed memory leak
ProxySQL used a patched version of MariaDB Connector C 2.1.0 (aka libmariadbclient). That version was patched to fix several bugs. Although, version 2.1.0 seems to be quite broken in handling Prepared Statements, so now MariaDB Connector C was upgraded to version 2.3.1 . Since this is a key compoenent in ProxySQL, several tests need to be performed because of this major change.
These are 2 memory leaks related to prepared statements * Resultset (MySQL_ResultSet() not deallocated * mysql_stmt_free_result() is now correctly called
Related to issue #171 Added variable mysql-query_cache_size_MB Also removed compiling of simple_kv.cpp Conflicts: lib/Makefile
Idle sessions (as defined by session_idle_ms) are not showed in processlist by default. If session_idle_show_processlist==true, they will show
This affects the epoll_threads. Will be way faster to determine if the connection is idle
