  translate-all: fix compiler warning and linked error

The code did use profile_getclock() but did not include
include/qemu/timer.h where this function is defined. The patch fixes this.

  qemu-char: use consistent idiom for removing sources

Always check that the source is active, and zero the tag afterwards.

The occurrence in pty_chr_state will trigger with the next patch, the
others are just theoretical.

  qemu-char: simplify pty polling

There is no need to use a timer and pty_chr_read to detect a connected
pty.  It is simpler to just call g_poll periodically and check for POLLHUP.
It is done once per second, and only if the pty is disconnected, so it
is cheap enough.

Tested with "-monitor pty" and "-serial mon:pty", both of which work
correctly and do not freeze QEMU.  (How to test ptys?  "socat -,raw,echo=0
/dev/pts/4,raw").

  qemu-char: correct return value from chr_read functions

Even if a CharDriverState's source is blocked by the front-end,
it must not be dropped. The IOWatchPoll that wraps it will take
care of adding and removing it to the main loop.  Only remove
the source when the channel is closed; and in that case, make sure
that the wrapping IOWatchPoll is removed too.

These should just be theoretical bugs.

  qemu-char: do not operate on sources from finalize callbacks

Due to a glib bug, the finalize callback is called with the GMainContext
lock held.  Thus, any operation on the context from the callback will
cause recursive locking and a deadlock.  This happens, for example,
when a client disconnects from a socket chardev.

The fix for this is somewhat ugly, because we need to forego polymorphism
and implement our own function to destroy IOWatchPoll sources.  The
right thing to do here would be child sources, but we support older
glib versions that do not have them.  Not coincidentially, glib developers
found and fixed the deadlock as part of implementing child sources.

  Add option to mlock qemu and guest memory

In certain scenario, latency induced by paging is significant and
memory locking is needed. Also, in the scenario with untrusted
guests, latency improvement due to mlock is desired.

This patch introduces a following new option to mlock guest and
qemu memory:

-realtime mlock=on|off

  qtest: Handle addresses and values for {in, out}[bwl] as unsigned

Handle the addresses and values for {in,out}[bwl] as unsigned (ie
with strtoul), as per the protocol specification comment. This fixes
a test failure in test_i440fx_defaults on 32-bit hosts where the test
tries to write 0x80000000 and qtest was instead writing 0x7fffffff.
