[PATCH 0/2] tools/libs: decouple more from mini-os

[Juergen Gross <jgross@xxxxxxxx>]

This small series removes some hard coupling of the Xen build with some
Mini-OS internals, especially the struct file layout and the internal
organization of the file handling.

This series depends on the Mini-OS series posted recently:

https://lists.xen.org/archives/html/xen-devel/2022-01/threads.html#00110

The main idea is to no longer have Xen library specific structures
inside struct file, or to let struct file layout depend on the
configuration of Mini-OS.

All Xen libraries needing a hook in struct file should use the now
available generic dev pointer and allocate the needed data dynamically.

Additionally Xen libraries should get the pointer of struct file via
the new get_file_from_fd() function instead of accessing directly the
files[] array, which might go away in future (e.g. in order to support
dynamic allocation of struct file as needed).
