We want to have the defacto standard syntax for labels ("L:" instead of "label L;"),
and fix some known bugs, before we enable this again.
The code is left intact (#ifdef'ed SP_GOTO) and the test cases are kept in
sp-goto.test, for the future...
mysql-test/r/sp-error.result:
Moved all goto tests to sp-goto.test.
mysql-test/r/sp.result:
Moved all goto tests to sp-goto.test.
mysql-test/t/disabled.def:
Disabled GOTO/LABEL (until the label syntax and some bugs can be fixed).
We keep the tests in sp-goto.test for the future, but disable for now.
mysql-test/t/sp-error.test:
Moved all goto tests to sp-goto.test.
mysql-test/t/sp.test:
Moved all goto tests to sp-goto.test.
sql/lex.h:
Disabled GOTO/LABEL (until the label syntax and some bugs can be fixed).
sql/sql_yacc.yy:
Disabled GOTO/LABEL (until the label syntax and some bugs can be fixed).
