branches/zip: Remove the dependency on the MySQL HASH table implementation.
Use the InnoDB hash table for keeping track of INNOBASE_SHARE objects.
struct st_innobase_share: Make table_name const uchar*. Add the member
table_name_hash.
innobase_open_tables: Change the type from HASH to hash_table_t*.
innobase_get_key(): Remove.
innobase_fold_name(): New function, for computing the fold value for the
InnoDB hash table.
get_share(), free_share(): Use the InnoDB hash functions.
innobase_end(): Free innobase_open_tables before shutting down InnoDB.
Shutting down InnoDB will invalidate all memory allocated via InnoDB.

branches/zip: When setting the PAGE_LEVEL of a compressed B-tree page
from or to 0, compress the page at the same time. This is necessary,
because the column information stored on the compressed page will
differ between leaf and non-leaf pages. Leaf pages are identified by
PAGE_LEVEL=0. This bug was reported as Issue #150.
Document the similarity between btr_page_create() and
btr_page_empty(). Make the function signature of btr_page_empty()
identical with btr_page_create(). (This will add the parameter "level".)
btr_root_raise_and_insert(): Replace some code with a call to
btr_page_empty().
btr_attach_half_pages(): Assert that the page level has already been
set on both block and new_block. Do not set it again.
btr_discard_only_page_on_level(): Document that this function is
probably never called. Make it work on any height tree. (Tested on
2-high tree by disabling btr_lift_page_up().)

branches/zip: Merge c2998 from branches/6.0, so that the same InnoDB Plugin
source tree will work both under 5.1 and 6.0. Do not add the test case
innodb_ctype_ldml.test, because it would not work under MySQL 5.1.
Refuse to create tables whose columns contain collation IDs above 255.
This removes an assertion failure that was introduced in WL#4164
(Two-byte collation IDs).
create_table_def(): Do not fail an assertion if a column contains a
charset-collation ID greater than 256. Instead, issue an error and
refuse to create the table.
The original change (branches/6.0 r2998) was rb://51 approved by Calvin Sun.

branches/zip: Some non-functional changes related to Issue #155.
buf_page_struct: Note that space and offset are also protected by
buf_pool_mutex. They are only assigned to by
buf_block_set_file_page(). Thus, it suffices for buf_flush_batch() to
hold just buf_pool_mutex when checking these fields.
buf_flush_try_page(): Rename "locked" to "is_s_latched", per Heikki's request.
buf_flush_batch(): Move the common statement mutex_exit(block_mutex)
from all if-else if-else branches before the if block. Remove the
redundant test (buf_pool->init_flush[flush_type] == FALSE) that was
apparently copied from buf_flush_write_complete().
buf_flush_write_block_low(): Note why it is safe not to hold buf_pool_mutex
or block_mutex. Enumerate the assumptions in debug assertions.

buf_flush_ready_for_flush(), buf_flush_try_page(): Assert that

comes from buf_flush_batch(), which already asserts this. The
assertion holds for all calls in the source code.

buf_flush_try_page(): Rename to buf_flush_page(), and change the
return type to void. Replace the parameters space, offset with bpage,
and remove the second page hash lookup. Note and assert that both
buf_pool_mutex and block_mutex must now be held upon entering the
function. They will still be released by this function.
buf_flush_try_neighbors(): Replace buf_flush_try_page() with
buf_flush_page(). Make the logic easier to follow by not negating the
precondition of buf_flush_page().

lock_rec_insert_check_and_lock(), lock_sec_rec_modify_check_and_lock():
Update the max_trx_id field also on the compressed page.
mlog_write_ulint(): Add UNIV_UNLIKELY hints. Remove trailing white space.
mlog_log_string(): Remove trailing white space.

occur in the heap, or it will be logged at a higher level.
