Michael Roth 957f1f99f2 guest agent: remove uneeded dependencies 
This patch tries to cull any uneeded library dependencies from the guest
agent to improve portability across various distros. We do so by being
as explicit as possible about in-tree dependencies rather than relying
on existing *-obj-y targets, and by manually setting LIBS for the
qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by
configure.

Avi Kivity 3a130f4ef0 memory: crack wide ioport accesses into smaller ones when needed 
The memory API supports cracking wide accesses into narrower ones
when needed; but this was no implemented for the pio address space,
causing lsi53c895a's IO BAR to malfunction.

Fix by correctly cracking wide accesses when needed.

Avi Kivity 164a4dcd8d memory: abstract cracking of write access ops into a function 
The memory API automatically cracks large reads and writes into smaller
ones when needed.  Factor out this mechanism, which is now duplicated between
memory reads and memory writes, into a function.
