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
use this interface.

In previosu series I remove v2 support for RAM (that was the version that was
supported when SaveVM v3 appeared).  Now we can't load RAM for any image saved in SaveVM v2, we can as well remove SaveVM v2 entirely.

Note: That SaveVM RAM was at v2 when General SaveVM support went from v2 to v3 makes talking about versions confusing at least

It don't work.  It fails in this check

        if (qemu_get_be32(f) != last_ram_offset)

With 512MB of ram, values were for me:

	v = 20c00000 last_ram_offset = 20840000

Last time that some code changed that was this one.

    commit 94a6b54f
    Implement dynamic guest ram allocation.
    (I.e. it has been broken since at least April)

Going back to the previous commit, ram load correctly, but vga screen gets
corrupted and ide don't load correctly.  At this point I decide that removing
support is the only viable thing.

The last user of the ram_compress_* were RAM_SAVE_FLAG_FULL flag, but
that flag was never ever been stored in an image. Mark the flag obsolete
and remove the functions.

stop using CharDriverState->focus in monitor.c, track state using
the mux events instead.  This also removes the implicit assumtion
that a muxed monitor allways has mux channel 0.

Lets put -chardev into use now.  With this patch applied chardev:name is
accepted as chardev specification everywhere, i.e. now you can:

	-chardev stdio,id=ttyS0
	-serial chardev:ttyS0

which does the same as '-serial stdio".

Muxing can be done this way:

	-chardev stdio,id=mux,mux=on
	-serial chardev:mux
	-monitor chardev:mux

You can mux more than two streams.

start switching chardevs to QemuOpts.  This patch adds the
infrastructure and converts the null device.

The patch brings two new functions:

qemu_chr_open_opts()
	same as qemu_chr_open(), but uses QemuOpts instead of a
	option char string.

qemu_chr_parse_compat()
	accepts a traditional chardev option string, returns the
	corresponding QemuOpts instance, to handle backward
	compatibility.

The patch also adds a new -chardev switch which can be used to create
named+unconnected chardevs, like this:

	-chardev null,id=test

This uses the new qemu_chr_open_opts.  Thus with this patch alone only
the null device works.  The other devices will follow ...
