Commit 1edddc99 authored by Ronald S. Bultje's avatar Ronald S. Bultje

Split RMContext into RMDemux/MuxContext and make them private in rmdec/enc.c.

Reason for this is that there are no shared entries in the demuxer/muxer
context, making it a mystery as to why it was shared between the two. See
"[PATCH] clean rmdemux/muxcontext" patch on mailinglist.
