dict_index_t: Enable the storage of trx_id.

row_prebuilt_t: Make many fields bit-fields to reduce the memory
footprint. Add index_usable.

ha_innobase::change_active_index(): Check if the index is usable and
set prebuilt->index_usable accordingly. Unfortunately, the return
status of this function is ignored by MySQL, and the actual refusal to
use the index must be made in row_search_for_mysql().

row_search_for_mysql(): Return DB_MISSING_HISTORY if
!prebuilt->index_usable.

convert_error_code_to_mysql(): Map DB_MISSING_HISTORY to
HA_ERR_TABLE_DEF_CHANGED.

innodb-index.test: Add a test case where access to a newly created
secondary index must be blocked for old transactions.

SHOW ENGINE INNODB MUTEX shows all mutexes and rw_locks. This can
be overwhelming particularly when the buffer pool is very large
(note that each block in buffer pool has at least one mutex, one
rw_lock and an additional mutex if rw_lock does not use atomics).
With this patch status of following mutexes and rw-locks is not shown:

1) block->mutex
2) block->lock
3) block->lock->mutex (if applicable)
4) All other mutexes and rw-locks for which number of os-waits are zero

new option --ignore_builtin_innodb

Starting 5.1.33, MySQL has a new option --ignore_builtin_innodb
for using the dynamic plugin. It is required to remove
innodb_plugin_init() in the plugin.

This patch removes innodb_plugin_init() as well as functions,
variables used by innodb_plugin_init().

buf_page_release(): Remove the assertion on in_flush_list.
The function is only holding block->mutex, not buf_pool_mutex.
This was reported by Sunny.  This was the only piece of code
that accessed in_flush_list while not holding buf_pool_mutex.

  branches/5.1: Fix a bug in multi-table semi-consistent reads.
  Remember the acquired record locks per table handle (row_prebuilt_t)
  rather than per transaction (trx_t), so that unlock_row should successfully
  unlock all non-matching rows in multi-table operations.
  This deficiency was found while investigating Bug #39320.
