* fix a possible memory leak (apply_filter returned before freeing)
* use apply_filters in process_major_frame
* revert back to checking bounds with 24 bitdepth, as huff offset takes
care of it

huff offset wasn't always within the bounds before, which lead to
corrupt encoding that didn't always trigger lossless check failures

A value of 24 and above can collaps the range to 0 which would not work.

This changes the separator character from comma to colon, but since this option
was only added recently I think it should be done for consistency with other
similar options.

This commit reuses the configuration options for VP8 that enables
temporal scalability for VP9. It also adds a way to enable three
preset temporal structures (refer to the documentation for more
detail) that can be used in offline encoding.

recvfrom() is not a cancellation point in pthreads-win32, see
https://sourceware.org/pthreads-win32/manual/pthread_cancel.html

In order to be able to cancel the reader thread on Win32 properly we first
shutdown the socket then call CancelIoEx to abort pending IO. Subsequent
recvfrom() calls will fail with WSAESHUTDOWN causing the thread to exit.

Fixes ticket #5717.
