MDEV-20366 Server crashes in get_current_user upon SET PASSWORD via SP
The opt_for_user subrule was incorrectly scanned before sp_create_assignment_lex(),
so the user name and the host were created on a wrong memory root.
- Reoganizing the grammar to make sure that sp_create_assignment_lex()
is called immediately after PASSWORD_SYM is scanned, so all attributes
are then allocated on its memory root.
- Moving the semantic code as methods to LEX, so the grammar looks as simple as possible.
- Changing text_or_password to be of the data type USER_AUTH*.
As a side effect, the LEX::definer member is now not used when processing
the SET PASSWORD statement. Everything is done using Bison's stack.
The bug sas introduced by this commit:
