Change of user interface to be more logical and more in line with expectations to work similar to old-style replication. User can now explicitly choose in CHANGE MASTER whether binlog position is taken into account (master_gtid_pos=current_pos) or not (master_gtid_pos= slave_pos) when slave connects to master. @@gtid_pos is replaced by three separate variables @@gtid_slave_pos (can be set by user, replicated GTIDs only), @@gtid_binlog_pos (read only), and @@gtid_current_pos (a combination of the two, most recent GTID within each domain). mysql.rpl_slave_state is renamed to mysql.gtid_slave_pos to match. This fixes MDEV-4474.

Solaris fixes: - Fixed that wait_timeout_func and wait_timeout tests works on solaris - We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO). - Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage) - Added missing sync_with_master Other bug fixes: - Free memory for rpl_global_gtid_binlog_state before exit() to avoid 'accessing uninitalized mutex' error. BUILD/FINISH.sh: Fixed issues on Solaris with ksh BUILD/compile-solaris-amd64-debug: Added missing -m64 flag configure.cmake: We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO) mysql-test/suite/rpl/t/rpl_gtid_mdev4473.test: - Added missing sync_with_master (fix by knielsen) sql-common/client.c: Added () to get rid of compiler warning sql/item_strfunc.cc: Fixed compiler warning sql/log.cc: Free memory for static variable rpl_global_gtid_binlog_state before exit() - If we are compiling with safemalloc, we would try to call sf_free() for some members after sf_terminate() was called, which would result of trying to access the uninitalized mutex 'sf_mutex' sql/multi_range_read.cc: Fixed compiler warnings of converting double to ulong. sql/opt_range.cc: Fixed compiler warnings of converting double to ulong or uint - Better to have all variables that can be number of rows as 'ha_rows' sql/rpl_gtid.cc: Added rpl_binlog_state::free() to be able to free memory for static objects before exit() sql/rpl_gtid.h: Added rpl_binlog_state::free() to be able to free memory for static objects before exit() sql/set_var.cc: Fixed compiler warning sql/sql_join_cache.cc: Fixed compiler warnings of converting double to uint sql/sql_show.cc: Added cast to get rid of compiler warning sql/sql_statistics.cc: Remove code that didn't do anything. (store_record() with record[0] is a no-op) storage/xtradb/os/os0file.c: Added __attribute__ ((unused)) support-files/compiler_warnings.supp: Ignore warnings from atomic_add_64_nv (was not able to fix this with a cast as the macro is a bit different between systems) vio/viosocket.c: Added more DBUG_PRINT

MDEV-4473: mysql_binlog_send() starts sending events from wrong GTID position in some master failover scenarios Suppose binlog file X has in its Gtid_list_event: 0-1-3,0-2-5, and suppose the slave requests to start replicating after 0-1-3. In this case the bug was that master would start sending events from the start of X. This is wrong, because 0-2-4 and 0-2-5 are contained in X-1, and are needed by the slave. So these events were lost. On the other hand, if the slave requested 0-2-5, then it _is_ correct to start sending from the beginning of binlog file X, because 0-2-5 is the last GTID logged in earlier binlogs. The difference is that 0-2-5 is the last of the GTIDs in the Gtid_list_event. The problem was that the code did not check that the matched GTID was the last one in the list. Fixed by checking if the gtid requested by slave that matches a gtid in the Gtid_list_event is the last event for that domain in the list. If not, go back to a prior binlog to ensure all needed events are sent to slave. mysql-test/include/show_events.inc: Backport --let $binlog_file=LAST, used by MDEV-4473 test case.
