Better error message than "Got error 5 during COMMIT"

[Raghavendra D Prabhu]

It is shown when max writeset size is exceed. Also, no one knows what error 5 here means either.

Test case is like this:

mysql> create table T (i int primAry key auto_increment, s varchar(1024));
mysql> set global wsrep_max_ws_size=1024;
mysql> insert into T (s) values (repeat('i',1024));
ERROR 1180 (HY000): Got error 5 during COMMIT

[Krunal Bauskar (krunal-bauskar)]

this needs addition of new error codes for WSREP.
can be done as part of error-handling revamp of wsrep.
