Hello Richard Mudgett, Jenkins2, George Joseph, 

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

    https://gerrit.asterisk.org/10150

to look at the new patch set (#5).

Change subject: rtp_engine: rtcp_report_to_json can overflow the ssrc integer value
......................................................................

rtp_engine: rtcp_report_to_json can overflow the ssrc integer value

When writing an RTCP report to json the code attempts to pack the "ssrc" and
"source_ssrc" unsigned integer values as a signed int value type. This of course
means if the ssrc's unsigned value is greater than that which can fit into a
signed integer value it gets converted to a negative number. Subsequently, the
negative value goes out in the json report.

This patch now packs the value as a json_int_t, which is the widest integer type
available on a given system. This should make it so the value no longer
overflows.

Note, this was caught by two failing tests hep/rtcp-receiver/ and
hep/rtcp-sender.
