Subject: input: optionally send trigger markers from common feed queue helper
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=f478c3e613ac047572cfad9c5dcde965050b17fe;p=libsigrok.git

input: optionally send trigger markers from common feed queue helper

This further simplifies callers, which need not care about flushing
previously queued samples before a trigger packet is sent. The queue
itself handles the order of packet initiation.
