Create separate function which only does the reading from DB and returns
the blob. Refactor __media_player_add_db to use this new function.
This slightly changes string allocation semantics: Instead of leaving
the string in the DB buffer and then letting
__media_player_add_blob_id() do the allocation and duplication, we now
immediately duplicate the string into the call's memory arena and
immediately free the DB buffers. __media_player_add_blob_id's
duplication then turns into a no-op thanks to call_ref().

Doing a simple prefix string match is not enough as there may be
keywords that are equal to a prefix of another keyword. Make sure the
keyword is followed by a space or newline or end of line. This also
removes the burden of having to skip over leading spaces in the CLI
handlers.

Use the call's memory arena to store strings (in particular the media
blob), and use intrusive allocation storage for the blob str itself.

This causes a termination with extreme prejudice. Useful for debugging
memory leak issues as it bypasses shutdown cleanup.

Change old code to directly return `str` objects instead of pointers to
allocated ones. Largely a no-op change but makes some code easier and
eliminates some old kludges.

Use single shared function to set `opts`. Set the "block egress" flag in
that same function. This fixes "block egress" not being set when media
is played from the player cache.

The cache index object contains an embedded RTP payload type, which uses
arena-allocated strings. Switch memory arena prior to calling
codec_init_payload_type(), and then switch back to call context when
done.

Introduce global generic memory arena variable, instead of having just
a call-specific memory arena. This makes it possible to use memory arena
outside of call contexts. Define previous call-specific functions in
terms of the generic ones.

If a decoder thread took over the player's coder, make sure we re-create
the AVPacket in the player's coder if needed.

`packet_sequencer_init()` initializes
`packet_sequencer_t` sequence to -1 always.
So make sure to set `uint16_t` later not to
an underflowing value, which can potentially
set the `uint16_t` object type to some insanely
big value.
