The need arose when working on Bug 26141, where it became
necessary to replace TABLE_LIST with its forward declaration in a few
headers, and this involved a lot of s/TABLE_LIST/st_table_list/.
Although other workarounds exist, this patch is in line
with our general strategy of moving away from typedef-ed names.
Sometime in future we might also rename TABLE_LIST to follow the
coding style, but this is a huge change.
