the field references of externally stored columns (BLOB pointers)
will not be left uninitialized after a successful optimistic insert.
This bug was spotted by Sunny.

row_upd_index_replace_new_col_vals(): Declare fetch_ext.

row_upd_index_replace_new_col_vals_index_pos(): Add a type conversion

row_upd_ext_fetch(): New function.

row_upd_index_replace_new_col_vals(),
row_upd_index_replace_new_col_vals_index_pos(): Fetch prefixes of
externally stored columns when they are needed for column prefix
indexes.  For memory allocation, add the parameter ext_heap.  Avoid
repeating the inner loop after finding a  matching upd_field->field_no.

column numbers are relative to the InnoDB table object, or numbers
returned by dict_col_get_no().  This will have to be ensured in
all calling code.

make use of dict_index_is_clust().

numbers are relative to the clustered index record.

btr_free_externally_stored_field(): Add some page type assertions
that were suggested by Sunny.

Fix the size of the static buffer for lock_table and lock_index.
I was not realizing that NAME_LEN contains the mbmaxlen multiplier and thus
a quote, when converted to 2 quotes, will take 2 bytes while there are 3
bytes reserved.

Add C test for innobase_convert_name() in addition to the mysql-test one.

set the "external storage" flag.  When parsing the undo log, do not
misinterpret a SQL NULL column for externally stored.

These bugs were spotted by Heikki and Sunny.

trx_undo_page_report_modify(): Set the UNIV_EXTERN_STORAGE_FIELD flag
when needed.

trx_undo_rec_get_partial_row(): Check for len == UNIV_SQL_NULL.

Bugfix1: Set innodb_locks.lock_index to NOT NULL.
If a column in INFORMATION_SCHEMA table has the flag
MY_I_S_MAYBE_NULL and it is not explicitly marked as NOT NULL
with the method ::set_notnull() then it is always rendered as
NULL by MySQL.

Bugfix2: Avoid crashes if lock_index is NULL. It is NULL for table
level locks.

Move test that depends on ucs2 to a separate file that is disabled if
ucs2 is not compiled in.

Move common SQL commands to an .inc file.

Synchronize the utf8 and ucs2 tests.

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().

Convert INFORMATION_SCHEMA tables' names to upper case so that they are
consistent with other INFORMATION_SCHEMA tables.

When the error output is enabled (at compile-time), a breakpoint

errors in the context where they occur.

Remove unnecessary code. Environment variables are passed to children anyway,
no need to export them.

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.

Introduce a generic soultion to the common problem that MySQL do not add
