There is a link hack in linux-user which produces an executable that
looks like PIE, but always has text relocations since all object files
isn't position-independent (compiled without -fpic/-fpie). Dynamic loader
has to do more work to load a binary with text relocations.
The best way to keep this functionality is to build a true PIE without
text relocations.

We need to define _XOPEN_SOURCE and __EXTENSIONS__ macros in order to get
CMSG_ and TIOCWIN macros defined. But then _POSIX_C_SOURCE gets defined, which
is (incorrectly) used as an indicator for existence of posix_memalign() in osdep.c.

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.
Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

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.

loadvm_state is called from: vl.c during startup, vmstart() is called after finishing loading. The other caller do_loadvm() does the call after a vm_stop(). At both places where we can be saving state we are stoped a few lines before

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 94a6b54fd6
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.

make the mux driver send mux_in and mux_out events when switching
focus while hooking up more handlers.
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.
