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

John Snow 085248ae87 libqos: Add migration helpers
libqos.c:
    -set_context for addressing which commands go where
    -migrate performs the actual migration

malloc.c:
    - Structure of the allocator is adjusted slightly with
      a second-tier malloc to make swapping around the allocators
      easy when we "migrate" the lists from the source to the destination.

John Snow 259342d34d libqos/ahci: Add ahci_clean_mem
Clean up guest memory being used in ahci_clean_mem, to be
called during ahci_shutdown. With all guest memory leaks removed,
add an option to the allocator to throw an assertion if a leak
occurs.

This test adds some sanity to both the AHCI library and the
allocator.

John Snow f6f363c1f4 libqos: Update QGuestAllocator to be opaque
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:
  tests/libqos/malloc.c:35:3: warning:
  redefinition of typedef 'QGuestAllocator' is a C11 feature
        [-Wtypedef-redefinition]

John Snow af77f2cd7a libqos: Split apart pc_alloc_init
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.

Marc Marí 292be092ad libqos: Convert malloc-pc allocator to a generic allocator
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.

Anthony Liguori 8a0743cf74 libqos: add malloc support
This is a very simple allocator for the PC platform.  It should
be possible to add backends for other platforms.
