Use g_new() & friends where that makes obvious sense

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

replay: notify CPU on event

This patch enables vCPU notification to wake it up
when new async event comes in replay mode.

The motivation of this patch is the following.
Consider recorded block async event. It is saved into the log
with one of the checkpoints. This checkpoint may be passed in
vCPU loop. In replay mode when this async event is read from
the log, and block thread task is not finished yet, vCPU thread
goes to sleep. That is why this patch adds waking up the vCPU
to process this finished event.

replay: flush rr queue before loading the vmstate

Non-empty record/replay queue prevents saving and loading the VM state,
because it includes pending bottom halves and block coroutines.
But when the new VM state is loaded, we don't have to preserve the consistency
of the current state anymore. Therefore this patch just flushes the queue
allowing the coroutines to finish and removes checking for empty rr queue
for load_snapshot function.

Replay is capable of recording normal BH events, but sometimes
there are single use callbacks scheduled with aio_bh_schedule_oneshot
function. This patch enables recording and replaying such callbacks.
Block layer uses these events for calling the completion function.
Replaying these calls makes the execution deterministic.

replay: don't process events at virtual clock checkpoint

As QEMU becomes more multi-threaded and non-synchronized, checkpoints
move from thread to thread. And the event queue that processed at checkpoints
should belong to the same thread in both record and replay executions.
This patch disables asynchronous event processing at virtual clock
checkpoint, because it may be invoked in different threads at record and
replay. This patch is temporary fix until the checkpoints are completely
refactored.

replay: flush events when exiting

This patch adds events processing when emulation finishes instead
of just cleaning the queue. Now the bdrv coroutines will be in consistent
state when emulator closes. It allows correct polling of the block layer
at exit.

replay: save vmstate of the asynchronous events

This patch fixes saving and loading the snapshots in the replay mode.
It is required for the snapshots created in the moment when the header
of the asynchronous event is read. This information was not saved in
the snapshot. After loading the vmstate replay continued with the file offset
passed the event header. The event header is lost in this case and replay
hangs.

replay: don't process async events when warping the clock

Virtual clock is warped from iothread and vcpu thread. When the hardware
events associated with warp checkpoint, then interrupt delivering may be
non-deterministic if checkpoint is processed in different threads in record
and replay.
This patch disables event processing for clock warp checkpoint and leaves
all hardware events to other checkpoints (e.g., virtual clock).

replay: push replay_mutex_lock up the call tree

Now instead of using the replay_lock to guard the output of the log we
now use it to protect the whole execution section. This replaces what
the BQL used to do when it was held during TCG execution.

We also introduce some rules for locking order - mainly that you
cannot take the replay_mutex while holding the BQL. This leads to some
slight sophistry during start-up and extending the
replay_mutex_destroy function to unlock the mutex without checking
for the BQL condition so it can be cleanly dropped in the non-replay
case.
