qemu-io: Fix warnings from static code analysis

Browse Source 
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.
