partitioned table
  
Post-pushbuild fix
  
Pushbuild detected a new need for lex initialization in
embedded server.

Fixed test for INSERT DELAYED in partitions_hash.test so that
it works with embedded server.

            partitioned table

Post-merge fix

A new need for lex initialization arose.

            the wrong buffer

handler::index_next_same() did not take into account that the
internally called function key_cmp_if_same() uses the fixed
buffer table->record[0] for key comparison instead of the
buffer provided by the caller of handler::index_next_same().

Added code to temporarily redirect table->record[0] and the fields
used for the key to the record buffer provided by the caller of
handler::index_next_same().

The test case is in partition.test already.

Post-merge fix. Moved test into 5.0 section.

Disabling and enabling indexes on a non-empty table grows the
index file.

Disabling indexes just sets a flag per non-unique index and does not
free the index blocks of the affected indexes. Re-enabling indexes
creates new indexes with new blocks. The old blocks remain unused
in the index file.

Fixed by dropping and re-creating all indexes if non-empty disabled
indexes exist when enabling indexes. Dropping all indexes resets
the internal end-of-file marker to the end of the index file header.
It also clears the root block pointers of every index and clears the
deleted blocks chains. This way all blocks are declared as free.

            partitioned table

Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".

Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code
uses a new temporary instance of a lex. But it does still refer
to the previously active lex. The delayd insert thread does not
initialize its lex though...

Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.

  "ALTER SERVER can cause server to crash"
  While retrieving values, it would erronously set the socket value
  to NULL and attempt to use it in strcmp().
  Ensure it is correctly set to "" so that strcmp may not crash.
