With the Xen side of this interface (soon to be) fixed to return real sizes,
userspace needs to be able to make the query.
Introduce xenforeignmemory_resource_size() for the purpose, bumping the
library minor version.
Update both all osdep_xenforeignmemory_map_resource() implementations to
understand size requests, skip the mmap() operation, and copy back the
nr_frames field.
For NetBSD, also fix up the ioctl() error path to issue an unmap(), which was
overlooked by c/s 4a64e2bb39 "libs/foreignmemory: Implement on NetBSD".

Instead of each library having an own include directory move the
official headers to tools/include instead. This will drop the need to
link those headers to tools/include and there is no need any longer
to have library-specific include paths when building Xen.
While at it remove setting of the unused variable
PKG_CONFIG_CFLAGS_LOCAL in libs/*/Makefile.
