The current timeout is set to only three seconds - and considering that
vring_wait_reply() or rather get_second() is not doing any rounding,
the real timeout is likely rather 2 seconds in most cases. When the
host is really badly loaded, it's possible that we hit this timeout by
mistake; it's even more likely if we run the guest in TCG mode instead
of KVM.
So let's increase the timeout to 30 seconds instead to ease this situation
(30 seconds is also the timeout that is used by the Linux SCSI subsystem
for example, so this seems to be a sane value for block IO timeout).

It's never a good idea to blindly read for size bytes as
returned by the server without first validating that the size
is within bounds; a malicious or buggy server could cause us
to hang or get out of sync from reading further messages.
It may be smarter to try and teach the client to cope with
unexpected context ids by silently ignoring them instead of
hanging up on the server, but for now, if the server doesn't
reply with exactly the one context we expect, it's easier to
just give up - however, if we give up for any reason other
than an I/O failure, we might as well try to politely tell
the server we are quitting rather than continuing.
Fix some typos in the process.

"-net" is clearly a legacy option. Yet we still use it in almost all
examples in the qemu documentation, and many other spots in the network
chapter. We should make it less prominent that users are not lured into
using it so often anymore. So instead of starting the network chapter with
"-net nic" and documenting "-net <backend>" below "-netdev <backend>"
everywhere, all the "-net" related documentation is now moved to the end
of the chapter. The new "-nic" option is moved to the beginning of the
chapter instead, with a new example that should demonstrate how "-nic"
can be used to shortcut "-device" with "-netdev". The examples in this
chapter are changed to use the "-device" and "-netdev" options or
"-nic" instead of "-net nic -net <backend>".
While we're at it, also remove a legacy remark about very old Linux
distributions. Also remove the "[...]" from the examples in this chapter
since we are not using this ellipsis in any other examples in our docu-
mentation.

This change is a workaround for a bug where mstatus.FS

This workaround will return dirty if mstatus.FS is
switched from off to initial or clean. According to
