A conversation in Wireshark might have two endpoints or might have no
endpoints; few if any have one endpoint. Distinguish between
conversations and endpoints.
Some AT commands and responses need context to be parsed correctly.
For example AT+CGMI's and AT+CGSN's responses are arbitrary strings
without "AT+" or "+" prefix (So saving the command is needed).
Another use case is when a command/response is followed by its data in
the following line, like AT+CGML (SMS content's listed in the line after
the "+CGML" line).
The implementation utilizes the USB conversation of the session to
pass information between packets.
Every new packets takes a 'snapshot' of the data stored in the conversation
before starting to parse and re-uses it when parsing & re-parsing of
that packet occurs.
Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation. Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).
The AT response may not contain a leading \r\n, so avoid checking
for this to determine if it's a response. This characters will be
removed as a part of white space removal anyway.
This fixes a -Wused-but-marked-unused compiler warning.
