In ASCII string based protocols it a printf() version that prints
directly to the message buffer may be useful.
Add function msgb_printf(), make sure that msg buffer bounderies
are not exceeded. If the end of the tail buffer is hit, return
with an error code.

truncating the unsigned long pointer msg->data to 'int' and then passin
git into msgb_resize_area() is unsafe as depending on the 32rd address
bit it will be eiether negative or positive. That will in turn change
the expected "Sub area is not fully contained in the msg data\n" error
message into "Negative sizes are not allowed\n" which is not what the
autotest case expects.

Use %td to print ptrdiff_t use %zu to print size_t,
include time.h on FreeBSD. Some more compiler warnings are
left but they require more thinking.

Currently the msgb error handling cannot be fully tested, since in
many cases osmo_panic will be called. This will in turn call abort().
Using an osmo_panic_handler that just returns will not help, since
many msgb functions rely on MSGB_ABORT to not return at all.
This commit uses an alternative osmo_panic_raise handler that just
calls longjmp to return to the test function.
Since some of this activity is logged to stderr where the strings may
contain variable parts like pointer addresses, stderr checking is
disabled in testsuite.at.

This tests several API functions of the msgb by checking the
invariant and by dumping resulting message buffers as hex.
