qemu-io: Fix warnings from static code analysis
Smatch complains about several global symbols which should be local.
Add the missing 'static' attributes and move the 'extern' declaration
of variable qemuio_misalign to qemu-io.h. This variable also changes
the type from 'int' to 'bool' which better fits documents its use.
