René Cannaò	0831740e45	Several enhancements on Query logger ...

Issue #871 Changing value at runtime causes the current file to be closed and a new one created - fixed logging for prepared statements: till 2.0.5 only some percentage of prepared statements was correctly logged Extended tables stats_mysql_query_digest and stats_mysql_query_digest_reset to also include sum_rows_affected and sum_rows_sent Extended `eventslog_reader_sample.cpp` to support the new enhancements	7 years ago

Yubao Liu	ae80f15315	fix crash on "proxysql restart" ... MySQL_HostGroups_Manager::get_MyConn_from_pool() inserts connection to mysrvc->ConnectionUsed, and this connections is also inserted to My_Thread->cached_connections which leads to double deallocation.

Yubao Liu	676fd93836	fix crash when execute "PROXYSQL STOP" and then query table "stats_mysql_processlist" ... After execute "PROXYSQL STOP", main() -> ProxySQL_Main_init_phase4___shutdown() is called, then main() -> ProxySQL_Main_init_phase2___not_started() is called, this function creates GloMTH and waits on GloVars.global.start_mutex, thus ProxySQL_Main_init_phase3___start_all() -> ProxySQL_Main_init_MySQL_Threads_Handler_module() isn't called. Before "PROXYSQL START" is executed, admin module will crash on query to stats_mysql_processlist.
