[Asterisk-code-review] res_pjsip_session: Apply intention behind requested formats. (asterisk[16])

[Joshua Colp]

Hello George Joseph, Friendly Automation, Benjamin Keith Ford, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/13958

to look at the new patch set (#4).

Change subject: res_pjsip_session: Apply intention behind requested formats.
......................................................................

res_pjsip_session: Apply intention behind requested formats.

When an outgoing channel is created a list of formats may
optionally be provided which is used as a request that the
formats be used if possible. If an endpoint is not configured
for any of the formats we ignore this request and use what is
configured. This has the side effect of also including other
stream types (such as video) that were not present in the
requested formats.

This change makes it so that the intention of the request is
preserved - that is if only an audio format is requested then
even if there is no joint audio format between the request and
the configuration we will still only place an audio stream in
the outgoing call.
