Call correct method to free up ffmpeg AVFrame objects

When ffmpeg AVFrame objects are freed, the current code calls
avcodec_free_frame(). However, this can cause "use after free"
errors. The correct call is to call avcodec_free_frame().

Also updating the remaining places that use av_free() to free up
an AVFrame to use avcodec_free_frame() instead.

Requires a roll of ffmpeg to pick up avcodec_free_frame().

Add a Connect_Remote_Host test.

The test is very similar to Connect_Local_Host.
I also made two changes in the webapp:
1. Added a helper to map a host name to the host id
2. Add an id to the host name cell in the host list for easy retrieval in the test.
