This adds support to basevm.py so that we always
drain the console chars. This makes use of
support added in an earlier commit that allows
QEMUMachine to use the ConsoleSocket.
This is a workaround we found was needed since
there is a known issue where QEMU will hang waiting
for console characters to be consumed.
We also added the option of logging the console to a file.
LOG_CONSOLE=1 will now log the output to a file.

We add the ConsoleSocket object, which has a socket interface
and which will consume all arriving characters on the
socket, placing them into an in memory buffer.
This will also provide those chars via recv() as
would a regular socket.
ConsoleSocket also has the option of dumping
the console bytes to a log file.
We also give QEMUMachine the option of using ConsoleSocket
to drain and to use for logging console to a file.
By default QEMUMachine does not use ConsoleSocket.
This is added in preparation for use by basevm.py in a later commit.
This is a workaround we found was needed for basevm.py since
there is a known issue where QEMU will hang waiting
for console characters to be consumed.

This is a cleanup patch to follow-up the patch which introduced TSAN.
This patch makes separate start_switch_fiber_ functions for TSAN and ASAN.
This does two things:
1. Unrelated ASAN and TSAN code is separate and each function only
has arguments that are actually needed.
2. The co->tsan_caller_fiber and co->tsan_co_fiber fields are only
access from within #ifdef CONFIG_TSAN.

The new -accel option does not accept colons in the parameters anymore
(since it does not convert the parameters to -machine accel=... parameters
anymore). Thus we can now remove the check for colons in -accel:
$ qemu-system-x86_64 -accel kvm:tcg
qemu-system-x86_64: -accel kvm:tcg: invalid accelerator kvm:tcg

move the vcpu throttling functionality into its own module.
This functionality is not specific to any accelerator,
and it is used currently by migration to slow down guests to try to
have migrations converge, and by the cocoa MacOS UI to throttle speed.
cpu-throttle contains the controls to adjust and inspect throttle
settings, start (set) and stop vcpu throttling, and the throttling
function itself that is run periodically on vcpus to make them take a nap.
Execution of the throttling function on all vcpus is triggered by a timer,
registered at module initialization.
No functionality change.

This code was introduced with SMP support in commit 6a00d60127,
later commit 267f685b8b moved CPU list management to common code
but forgot this code. Move now and simplify ifdef'ry.
