trx rollback or purge
This patch does not relax the failing debug assertion during purge.
That will be revisited once we have managed to repeat the assertion failure.
row_upd_changes_ord_field_binary_func(): Renamed from
row_upd_changes_ord_field_binary(). Add the parameter que_thr_t* in
UNIV_DEBUG builds. When the off-page column cannot be retrieved,
assert that the current transaction is a recovered one and that it is
the one that is currently being rolled back.
row_upd_changes_ord_field_binary(): A wrapper macro for
row_upd_changes_ord_field_binary_func() that discards the que_thr_t*
parameter unless UNIV_DEBUG is defined.
row_purge_upd_exist_or_extern_func(): Renamed from
row_purge_upd_exist_or_extern(). Add the parameter que_thr_t* in
UNIV_DEBUG builds.
row_purge_upd_exist_or_extern(): A wrapper macro for
row_purge_upd_exist_or_extern_func() that discards the que_thr_t*
parameter unless UNIV_DEBUG is defined.
Make trx_roll_crash_recv_trx const. If there were a 'do not
dereference' attribute, it would be appropriate as well.

row_upd_changes_ord_field_binary(): Do not return TRUE if the update
vector changes a column that is covered by a prefix index, but does
not change the column prefix. Add the row_ext_t parameter for
determining whether the prefixes of externally stored columns match.
dfield_datas_are_binary_equal(): Add the parameter len, for comparing
column prefixes when len > 0.
innodb.test: Add a test case where the patch of Bug #55284 failed
without this fix.
