innodb_information_schema.test. Add tests that display most columns from
INFORMATION_SCHEMA.INNODB_LOCKS. Test that quoting of table names works
and respects SQL_MODE='ANSI_QUOTES'.
innobase_print_identifier(): Remove.
innobase_convert_identifier(): New function,
based on innobase_print_identifier().
innobase_convert_name(): New function, similar to ut_print_namel(), but
using a memory buffer.
ut_print_namel(): Use innobase_convert_name().
fill_innodb_locks_from_cache(): Convert lock_table and lock_index by
calling innobase_convert_name().
Implement a limit on the memory used by the INNODB_TRX, INNODB_LOCKS and
INNODB_LOCK_WAITS tables. The maximum allowed memory is defined with the
macro TRX_I_S_MEM_LIMIT.

Add the query in information_schema.innodb_trx.trx_query. Add it even
though it is available in information_schema.processlist.info to make
inconsistencies between those two tables obvious.
It is rather confusting to see a transaction shown in innodb_trx and
innodb_locks that holds a lock on one table and the corresponding query
in processlist executing INSERT on another table. We do not want users
to contact us asking to explain that. It is caused by the fact that the
data for innodb_* tables and processlist is fetched at different time.

ha_innobase::write_row(): The printf format %p expects const void*.
STRUCT_FLD: Do not use the GCC extension when __STRICT_ANSI__ is defined.
row_merge_read_clustered_index(): Compound initializers must not contain
variables. Assign to struct fields instead.
Add innodb_locks.lock_data column and some relevant tests.
For record locks this column represents the ordering fields of the
locked row in a human readable, SQL-valid, format.
Approved by: Marko
INNODB_ZIP and INNODB_ZIP_RESET from ha_innodb.cc to i_s.cc.
plugin_author, END_OF_ST_FIELD_INFO, i_s_info: New common constants.
trx_i_s_common_deinit(): Renamed to i_s_common_deinit().
innodb_lock_waits. See
https://svn.innodb.com/innobase/InformationSchema/TransactionsAndLocks
for design notes.
Things that need to be resolved before this goes live:
* MySQL must add thd_get_thread_id() function to their code
http://bugs.mysql.com/30930
* Allocate memory from mem_heap instead of using mem_alloc()
* Copy table name and index name into the cache because they may be
freed later which will result in referencing freed memory
