Fix that by adding -D_FUNCTION_DEF to READLINE_CFLAGS to fix *Function
related warnings and add a check for stdarg.h so we have HAVE_STDARG_H
defined that's needed by the readline headers to use proper rl_message
declaration.

Currently, any attempt to change MTU on an interface that is
plugged to a running domain is silently ignored. We should either
do what's asked or error out. Well, we can update the host side
of the interface, but we cannot change 'host_mtu' attribute for
the virtio-net device. Therefore we have to error out.

While reworking client side of streams, I had to postpone payload
decoding so that stream holes and stream data can be
distinguished in virNetClientStreamRecvPacket. That's merely what
18944b7a does. However, I accidentally removed one important
bit: when server sends us an empty STREAM packet (with no
payload) - meaning end of stream - st->incomingEOF flag needs to
be set. It used to be before I touched the code. After I removed
it, virNetClientStreamRecvPacket will try to fetch more data from
the stream, but it will never come.

Commit 24d4a0a1 removed the non-existent "dying" state from the list
of possible domain states given in the virsh manpage, but didn't
correct the count of states from 8 down to 7. This patch fixes that
mismatch by completely removing any reference to the exact number of
states (thus preventing a potential future mismatch), while wording
the sentence in a more readable/truthful manner.

When adding the aliased serial stub console, the structure wasn't
properly allocated (VIR_ALLOC instead of virDomainChrDefNew) which then
resulted in SIGSEGV in virDomainChrSourceIsEqual during a serial device

When persistent migration of a transient domain is requested but no
custom XML is passed to the migration API we would just let the
destination daemon make a persistent definition from the live definition
itself. This is not a problem now, but once the destination daemon
starts replacing the original CPU definition with the one from migration
cookie before starting a domain, it would need to add more ugly hacks to
reverse the operation. Let's just always send the persistent definition
in the cookie to make things a bit cleaner.
