Description:
sql_class.h contains the THD, and thus is included from almost everything. It is also very slow to compile. We should make it faster by splitting out code and forward-declaring more types.

Ideally, the THD should simply contain fewer variables instead of being used as a grab-bag for everything, but this bug is not going to deal with that.

How to repeat:
N/A

Suggested fix:
