Current default round-robin way of distributing VCPUs among
NUMA nodes might be wrong in case on multi-core/threads
CPUs. Making guests confused wrt topology where cores from
the same socket are on different nodes.
Allow a machine to override default mapping by providing
MachineClass::cpu_index_to_socket_id()
callback which would allow it group VCPUs from a socket
on the same NUMA node.

Users of virtio-serial may want to know when a port becomes writable. A
port can stop accepting writes if the guest port is open but not being
read from. In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.
When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

The command handler is a union of two function types. If
cmd->user_print is set, handle_user_command() calls
cmd->mhandler.cmd_new(), else cmd->mhandler.cmd().
Command definitions must therefore either set both user_print() and
mhandler.cmd_new(), or only mhandler.cmd().
quit's sets user_print and mhandler.cmd(). handle_user_command()
calls hmp_quit() through mhandler.cmd_new() rather than
mhandler.cmd(), i.e. through a function pointer with a different type.
Broken in commit 7a7f325, v1.0.
Works in practice because hmp_quit() doesn't use its arguments, and
handle_user_command() ignores its function value.

2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.
This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.
This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.
This removes unused qemu_time_start and tlb_flush_time.
