Re #2147 (misc): Fix incorrect call state info on incoming call in PJSUA2
In PJSUA2, due to ticket #1916, on_incoming_call() can be called earlier, during on_create_media_transport().

At this time, call->inv->state is still INV_STATE_NULL (instead of INV_STATE_INCOMING).

This patch only fixes the call info, but doesn't change the invite state itself.

Re #2147 (misc): Add assertion in pjmedia_port_info_init() to prevent division by zero.

Re #2147 (misc): Fixed build error of undefined reference to `pjmedia_srtp_enum_crypto' if PJMEDIA_HAS_SRTP is disabled.

Thanks to Alexei Gradinari for the patch

Re #2147 (misc): Add pjmedia_transport_media_stop() to streamutil sample app, for good practice since we now require media transport to be started since #2097

[nanang]

In 5910:

In 5946:

Re #2147 (misc): Contact params update when modifying account

The current contact params updates are not applied when calling pjsua_call_modify(). Updating contact header can be quite complicated so a simpler workaround is to trigger account registration first (the same solution is used to update force_contact).

Thanks to Lars Olsson for the report.

In 5950:
