Fix --enable-profiler compilation.

There's a header file inclusion ordering problem between cpu-all.h
and qemu-timer.h, such that cpu_get_real_ticks is not defined when
we attempt to use it in profile_getclock.

Make cpu_get_real_ticks use mfspr

PowerPC CPUs have had two ways to read the time base for quite some time now.
They provide it using the mfspr instruction or - if a special bit is set in
that opcode - using mftb. For timekeeping we're currently using mftb....

Compile qemu-timer only once

Arrange various declarations so that also non-CPU code can access
them, adjust users.

Move CPU specific code to cpus.c.

add qemu_get_clock_ns

Some places use get_clock directly because they want to access the
rt_clock with nanosecond precision. Add a function to do exactly that
instead of using internal interfaces.

Introduce QEMU_CLOCK_HOST

Despite its name QEMU_CLOCK_REALTIME is (normally) not using
CLOCK_REALTIME / the host system time as base. In order to allow also
non-trivial RTC emulations (MC146818) to follow the host time instead of
the virtual guest time, introduce the new clock type QEMU_CLOCK_HOST. It...

Make get_ticks_per_sec() a static inline

ticks_per_sec is a constant. There's no need to store it as a variable as it
never changes since our time is based on units.

Convert get_ticks_per_sec() to a static inline and move the constant into
qemu-timer.h. Remove all references to QEMU_TIMER_BASE so that we consistently...

variable timer intervals

This patch introduces dynamic timer intervals: we slow down the refresh
rate when there in no much activity but we get back to a fast refresh
rate when the activity resume.

Please note that qemu_timer_expired is not an inline function any more...
