Implements unrotated planar YUV 4:2:0 -> RGB24 conversions in Y2R.
Currently only the Y (luma) channel is used, so the results don't
contain color. This will be added in a later PR at some point.
This is enough to get all currently know Moflex videos to decode. (Some
don't display on-screen due to seemingly unrelated reasons.)
Thanks to @archshift for doing the initial implementation which I
cleaned up and then fixed the 8x8 block mode.
It provided a large increase in complexity of the logging system while
having a negligible performance impact: the usage patterns of the ring
buffer meant that each log contended with the logging thread, causing
it to effectively act as a synchronous extra buffering.
Also removed some broken code related to filtering of subclasses which
was broken since it was introduced. (Which means no one ever used that
feature anyway, since, 8 months later, no one ever complained.)
Stubbed CreateMemoryBlock
Using Berkeley sockets, and Winsock2.2 on Windows.
So far ftpony creates the socket and accepts incoming connections
SOC_U: Renamed functions to maintain consistency
Also prevents possible scope errors / conflicts with the actual Berkeley socket functions
SOCU: Close all the opened sockets when cleaning up SOCU
