The current documentation of the various foo_image_format settings in
qemu.conf subtly implies they are only used for specifying compression.
Patch1 of this small series attempts to clarify and improve the description
of the settings. It defines image format as a way to specify the desired
layout of guest memory blocks on disk.

Patch2 changes the name of the 'compressed' field of virQEMUSaveHeader to
'format', removing implication that format == compressed in the code.

This patch could have went a bit further in replacing the use of 'compressed' 
with 'format'. I've sent a V2 of the series
