2df8814ae7 lavf/webm_chunk: Respect buffer size
The last argument of av_strlcpy is supposed to contain the size of the
destination buffer, but it was filled with the size of the source
string, effectively negating its very purpose.

ccb8f67499 lavf/webm_chunk: Fix a memory leak.
Fix a duplicate memory allocation. priv_data should be allocated
in line 64 call to avformat_alloc_output_context2 since we pass
the correct AVFormat to it. This removes the duplicate allocation.

e2784a1d96 lavf/webm_chunk: Use dyn_buf to write chunks
Use dyn_duf to write chunks so that we create the actual chunk
file only after the entire chunk data is available. This will help
not confuse other software looking at the chunk file (e.g. a web
server) by seeing a zero length file when ffmpeg is writing into
it.
