Final version of patch.
Adds support for specifying of DEFAULT NOW() and/or ON UPDATE NOW()
clauses for TIMESTAMP field definition.
Current implementation allows only one such field per table and
uses several unireg types for storing info about this properties of
field. It should be replaced with better implementation when new
.frm format is introduced.
Added new test cases for this, and adjusted old tests accordingly,
and new error codes and messages.
Fixed bugs in some tests (bug2673 and use test).
Added debug printing of instructions in SPs.
Phase 2: Make SPs belong to a DB, and use qualified names.
As a side effect, using USE in an SP is no longer allowed.
(It just doesn't work otherwise.)
"--read-only gives weird error on update".
It is not fixable in 4.0 because it requires modifying
the sql/share/*/errmsg.txt files. So it is fixed in 4.1 like this:
the ER_SKIP_GRANT_TABLES is replaced by a more generic
ER_OPTION_PREVENTS_STATEMENT which can be used both for
"can't do this because of --skip-grant-tables" and
"can't do this because of --read-only" (for this we don't use
ER_CANT_UPDATE_WITH_READLOCK anymore).
So now the message for --read-only is:
"The MySQL server is running with the --read-only option so
cannot execute this statement".
I had not corrected these languages.
As it has been discussed with the docs team, the new messages will be merged
to 4.1, and then will be translated in 4.1 (they will remain in English
in 4.0).
Cleaned up embedded library access and query cache handling
Changed min stack size to 128K (to allow longer MyISAM keys)
Fixed wrong priority for XOR (should be less than NEG to get -1^1 to work)
