Allow devices/drivers to register themselves via constructors.
Destructors are not needed (can be registered from a constructor)
and "priority" has been renamed and changed to an enum for clarity.

osdep.c is built in both as a toplevel target independant object, and
as a per-target object because of kqemu dependencies. Under some
circumstances make picks up the wrong one.
Build the former as tool-osdep to avoid this conflict.

Include assert.h from qemu-common.h and remove other direct uses.
cpu-all.h still need to include it because of the dyngen-exec.h hacks

The vga_ram_size argument to machine init functions always has the same
value, and is ignored by many machines (including SPARC32 which has an
obsolete ifdef for VGA_RAM_SIZE).
Remove it and push VGA_RAM_SIZE into vga_int.h.

Now we can safely call AUD_init multiple times we can push it down to
individual audio devices, rather than having to pass it from the board
init.
Signed-off-by: Paul Brook <paul@codesourcery.com>
Failure to initialize the audio subsystem is not handled consistently.
Where it is handled it has guest visible effects, which is wrong.
We already have a "nosound" audio driver as a last resort, so trying to
proceed without an audio backend seems pointless.
Also protect against multiple calls to AUD_init so that this can be
pushed down into individual devices.

1) Changed usage of malloc,free,strdup to qemu_malloc,qemu_free,qemu_strdup
2) Some coding style fixes (based on CODING_STYLE document)
3) Free struct addrinfo *res after failure of listen

All VGA devices share a common field subset; currently they do so by
a macro which defines the common fields inline their state structures,
relying on the the common state being placed at offset 0 in the structure.
This makes refactoring the code difficult and requires a lot of error prone
casts.
Replace the macro by a new VGACommonState structure, and the casts by
regular field access and container_of() for upcasts.

This patch makes the range checks for block requests more strict: It fixes a
potential integer overflow and checks for negative offsets. Also, it adds the
check for compressed writes.

Remove cpu features that are not supported by kvm from the cpuid features
reported to the guest.

QEMU allows adding or removing cpu features by using the syntax '-cpu +feature'
or '-cpu -feature'. Some cpuid features cause more than one bit to be set or
cleared; but QEMU stops after just one bit has been modified, causing the
feature bits to be inconsistent.
Fix by allowing all feature bits corresponding to a given name to be set.
