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.
include/mysqld_error.h:
Added error codes for case when we have more than one column with NOW()
in DEFAULT or ON UPDATE clauses and for case when we are using ON UPDATE
clause with wrong type.
mysql-test/r/create.result:
Added tests for using of DEFAULT NOW() and ON UPDATE NOW() with
non-TIMESTAMP fields.

in SHOW CREATE TABLE.

fields definitions.
sql/field.cc:
Added support for various combinations of DEFAULT and ON UPDATE clauses
for TIMESTAMP field.
Setting TABLE::timestamp* members for TIMESTAMP fields with auto-set
option taking into account their unireg type (which corresponds to
various DEFAULT/ON UPDATE values combinations). Replaced
TABLE::time_stamp with TABLE::timestamp_default_now/on_update_now
couple moved their setup to separate method set_timestamp_offsets(),
which now is called from open_table instead of Field_timestamp cons.
sql/field.h:
Added more unireg types for handling of DEFAULT NOW() and ON UPDATE
NOW() for TIMESTAMP fields.
Fixed value corresponding to DEFAULT item for TIMESTAMP field.

for each statement to open_table().
sql/sql_insert.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of
old TABLE::time_stamp. Added check for case then REPLACE could not
be converted to UPDATE because of different DEFAULT/ON UPDATE values
for TIMESTAMP field.
sql/sql_lex.h:

sql/sql_load.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of

This is to enable table handlers to implement online create/drop index.
It consists of some parts:
- New default handler methods in handler.h
- Split of mysql_alter_table. It decides if only one kind of
alteration is to be done (e.g. only create indexes or only drop
indexes etc.) It then calls the specialized new handler method if
the handler implements it. Otherwise it calls real_alter_table.
- The parser sets flags for each alter operation detected in a
command. These are used by mysql_alter_table for the decision.
- mysql_prepare_table is pulled out of mysql_create_table. This is
also used by mysql_create_index to prepare the key structure array
for the handler. It is also used by mysql_create_index and
mysql_drop_index to prepare a call to mysql_create_frm.
- mysql_create_frm is pulled out of rea_create_table for use by
mysql_create_index and mysql_drop_index after the index is
created/dropped.
Thanks to Antony who supplied most of the changes.

Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New virtual handler methods with default implementation and return flags.
sql/mysql_priv.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New function prototypes. mysql_prepare_table is pulled out of
mysql_create_table. It prepares a table structure, which is used by
mysql_create_table, mysql_create_index and mysql_drop_index.
real_alter_table is pulled out of mysql_alter_table. The latter only
looks if the requested operation can be done by specialized functions
or else calls real_alter_table, which does the real thing.
mysql_add_column and mysql_drop_colunm are for future use. They simply
call real_alter_table. mysql_create_frm is pulled out of
rea_create_table. It is called also from mysql_create_index and
mysql_drop_index after successful create/drop index.
mysql_alter_table prototype is extended by the new alter_flags argument.
sql/sql_base.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_create_index and mysql_drop_index moved to sql_table.cc.

the new handler functions if the handler implements them.
mysql_add_column and mysql_drop_column are for future use. They simply
call real_alter_table. mysql_alter_table only decides which function
to use for the requested operation. real_alter_table implements most
of what mysql_alter_table did before.

Actually it is not a bug but right behavior observed as pefomance
degradation after we have forced Item_field::fix_fields() to
re-execute each time when we are executing prep stmt.
This patch implements small optimization which heals this bad
behavior. We are caching field position in TABLE::field array in
Item's member and are using this position for speeding up field
lookups in fix_fields() in case of its re-execution.
sql/item.cc:
Added cached_field_index member to Item_ident for caching field
position in TABLE::field array for quicker field lookup in case
fix_fields() is executed twice.
sql/item.h:
Added cached_field_index member to Item_ident for caching field
position in TABLE::field array for quicker field lookup in case
fix_fields() is executed twice.
sql/mysql_priv.h:
Now find_field_in_table has one more in-out parameter which is used
for caching field index in TABLE::field array stored for quicker
field look up.
sql/sql_acl.cc:
Now find_field_in_table has one more in-out parameter which is used
for caching field index in TABLE::field array stored for quicker
field look up.
sql/sql_base.cc:
Optimization: Now when we are looking up Field by its name we are
caching its position in TABLE::field array in Item_ident::cached_field_index,
so when we will call fix_fields() second time for this item (e.g.
when we are re-executing prep statement) we can reuse this index
to speed up this lookup.
sql/table.cc:
Now we storing in TABLE::name_hash pointers to elements of
TABLE::field array, because this allows easily retrieve index
of field in this array when it is looked up by its name.
sql/table.h:
Added comment claryfying what we store in TABLE::name_hash.
