ha_innobase::create(): Add the local variable row_type = form->s->row_type.
Adjust it to ROW_TYPE_COMPRESSED when ROW_FORMAT is not specified or inherited

explicitly specified.

when renaming tables

Allocate the table name using ut_malloc() instead of table->heap because
the latter cannot be freed.

Adjust dict_sys->size calculations all over the code.

Change dict_table_t::name from const char* to char* because we need to
ut_malloc()/ut_free() it.

Valgrind warning happpens because of uninitialized null bytes.
In row_sel_push_cache_row_for_mysql() function we fill fetch cache
with necessary field values, row_sel_store_mysql_rec() is called
for this and leaves null bytes untouched.
Later row_sel_pop_cached_row_for_mysql() rewrites table record
buffer with uninited null bytes. We can see the problem from the
test case:
At 'SELECT...' we call row_sel_push...->row_sel_store...->row_sel_pop_cached...
chain which rewrites table->record[0] buffer with uninitialized null bytes.
When we call 'UPDATE...' statement, compare_record uses this buffer and
valgrind warning occurs.
The fix is to init null bytes with default values.
