Except for specific cases where the use of %esp changes the encoding of
the instruction, it's cleaner to use TCG_REG_CALL_STACK instead of
TCG_REG_ESP.

The code for stack allocation for call arguments is way too simplistic
to actually work on targets with non-trivial stack allocation policies,
e.g. ppc64. We've also already allocated TCG_STATIC_CALL_ARGS_SIZE worth
of stack for calls which should be well more than any helper needs.
Remove broken dynamic stack allocation code and replace it with an assert.
Should dynamic stack allocation ever be needed again, target specific
functions should be added.
Thanks to Richard Henderson for the analysis.

Pass CPUState to do_interrupt(). This is needed by later patches.

Several x86 specific functions are called from cpu-exec.c with the
assumption that global env register is valid. This will be changed
later, so make the functions use caller supplied CPUState parameter.
It would be cleaner to move the functions to helper.c, but there are
quite a lot of dependencies between do_interrupt() and other functions.
Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead
of calling the helper (which uses global env, AREG0) directly.

do_interrupt() was mixing CPUState pointer passed from caller
and global env (AREG0).
Fix by moving the function to helper.c. Introduce a helper for calling
change_pstate() safely from outside of execution context.

- do not use Linux headers on non-Linux hosts
- fix kvmclock for !CONFIG_KVM

When we create the symlinks to source tree files, don't create them
if the file is not actually present in the source tree; this will
happen if the file is in a git submodule that wasn't checked out.
This also avoids the odd effect where an in-source-tree configure
will end up creating the missing file as a symlink to itself.

Correct a number of minor errors in the OHCI wakeup implementation:
* when the port is suspended but the controller is not, raise RHSC
* when the controller is suspended but the port is not, raise RD
* when the controller is suspended, move it to resume state

the attention of the guest OS if it tried to do so at the wrong time.

This is used to indicate at which speed[s] the device can operate,
so that this can be checked to match the ports capabilities when it gets
attached to a bus.
Note that currently all usb1 emulated device claim to be fullspeed, this
seems to not cause any problems, but still seems wrong, because with real
hardware keyboards, mice and tablets usually are lo-speed, so reporting these
as fullspeed devices seems wrong.

Add properties for the wakeup rate and the max number of frames ehci
will process at once.
The wakeup rate defaults to 1000 which equals the usb frame rate. This
can be reduced to make qemu wake up less often when ehci is active.
In case the wakeup rate is reduced or the ehci timer is delayed due to
latency issues elsewhere in qemu ehci will process multiple frames at
once. The maxframes property specifies the upper limit for this.
