Much of fw_cfg.h's contents is #ifndef NO_QEMU_PROTOS.  This lets a
few places include it without satisfying the dependencies of the
suppressed code.  If you somehow include it with NO_QEMU_PROTOS, any
future includes are ignored.  Unnecessarily unclean.

Move the stuff not under NO_QEMU_PROTOS into its own header
fw_cfg_keys.h, and include it as appropriate.  Tidy up the moved code
to please checkpatch.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

To avoid the architecture-specific implementations of the generic qtest
allocator having to know about fields within the allocator, add a
page_size setter method for users or arch specializations to use.
The allocator will assume a default page_size for general use, but it
can always be overridden.

Since this was the last instance of code directly using properties of the
QGuestAllocator object directly, modify the type to be opaque and move
the structure inside of malloc.c.

mlist_new, which was previously exported, is made static local to malloc.c,
as it has no external users.

[Peter Maydell <peter.maydell@linaro.org> reported the following clang
warning:

Move the list-specific initialization over into
malloc.c, to keep all of the list implementation
details within the same file.

The allocation and freeing of these structures are
now both back within the same layer.

The allocator in malloc-pc has been extracted, so it can be used in every arch.
This operation showed that both the alloc and free functions can be also
generic.
Because of this, the QGuestAllocator has been removed from is function to wrap
the alloc and free function, and now just contains the allocator parameters.
As a result, only the allocator initalizer and unitializer are arch dependent.

Implement a simple first-fit memory allocator that
attempts to keep track of leased blocks of memory
in order to be able to re-use blocks.

Additionally, allow the user to specify when
initializing the device that upon cleanup,
we would like to assert that there are no
blocks in use. This may be useful for identifying
problems in qtests that use more complicated
set-up and tear-down routines.

This functionality is used in my upcoming ahci-test v2
patch set, but I didn't see fit to enable it for any
existing tests, which will continue to operate the
same as they have prior.
