[PATCH v4 11/20] libqtest: make qtest_bufwrite send "atomic"

["Oleinik, Alexander" <alxndr@bu.edu>]

From: Alexander Oleinik <alxndr@bu.edu>

When using qtest "in-process" communication, qtest_sendf directly calls
a function in the server (qtest.c). Combining the contents of the
subsequent socket_sends into the qtest_sendf, makes it so the server can
immediately handle the command, without building a local buffer and
waiting for a newline.
