Adds an additional transform in the ext_tx experiment that
is a 2d DST1-DST1 combination.
To enable use --enable-ext-tx --enable-dst1.
This needs to be later extended to combine DST1 with DCT
or ADST.

This change is made in preparation for a
subsequent patch which adds acceleration
for the highbitdepth transform functions.
The highbitdepth transform functions attempt
to use 16/32bit sse instructions where possible,
but fallback to using the C implementations if
potential overflow is detected. For this reason
the dct routines are made global so they can be
called from the acceleration functions in the
subsequent patch.

Adding these functions to encapsulate tx_type check. Changing TX_TYPE to
int to match the declaration in vo9_rtch.h.
