Cleanup: remove TIME_FUZZY_DATE.
Introduce TIME_FUZZY_DATES which means "very fuzzy, the resulting
value is only used for comparison. It can be invalid date, fine, as long as it can be
compared".
Updated many tests results (they're better now).
Backport to 5.5
(external Bug#69407 Build warnings with mysql)
support-files/build-tags:
Run etags on sql_yacc.yy, ignore other .yy files
unittest/mysys/explain_filename-t.cc:
NO_PLAN seems to fail on some platforms, use the actual number instead.
Syntax modified to allow statements:
ALTER TABLE ADD/DROP COLUMN
ALTER TABLE ADD/DROP INDEX
ALTER TABLE ADD/DROP FOREIGN KEY
ALTER TABLE ADD/DROP PARTITION
ALTER TABLE CHANGE COLUMN
ALTER TABLE MODIFY COLUMN
DROP INDEX
to have IF (NOT) EXISTS options.
Appropriate implementations added to mysql_alter_table().

TO SIGNED
Problem:
When we are joining types (of fields) in case of a union, we usually
upgrade the datatypes to the largest present in the query.
In case of mediumint, it is not happening.
Analysis:
When joined with types LONG and LONGLONG, mediumint should get
upgraded to LONG and LONGLONG respectively.
W.r.t the given query, constant '1' will be created as a LONGLONG
internally and SIGNED flag is enabled. As a result, while combining
types for the field, LONGLONG along with MEDIUMINT gets converted
to LONG first. LONG with MEDIUMINT(of the third select) gets converted
to MEDIUMINT. SIGNED FLAG would be that of the first field's.
As a result, the final result would be SIGNED MEDIUMINT.
Fix:
While joining types, MEDIUMINT with LONGLONG and MEDIUMINT with LONG
is converted to LONGLONG and LONG respectively. Also, made some
changes for FLOAT and DOUBLE.
sql/field.cc:
Changed merge types for MEDIUMINT.
The invalid implementation of the method Field_bit::cmp_max could
trigger a valgrind complain or could lead to incorrect statistical
data when collecting engine-independent statistics on BIT fields.
Generalized support for auto-updated and/or auto-initialized timestamp
and datetime columns. This patch is a reimplementation of MySQL's
"WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to
ease future merges, this implementation reused few function and variable
names from MySQL's patch, however the implementation is quite different.
TODO:
The only unresolved problem in this patch is the semantics of LOAD DATA for
TIMESTAMP and DATETIME columns in the cases when there are missing or NULL
columns. I couldn't fully comprehend the logic behind MySQL's behavior and
its relationship with their own documentation, so I left the results to be
more consistent with all other LOAD cases.
The problematic test cases can be seen by running the test file function_defaults,
and observing the test case differences. Those were left on purpose for discussion.
