A large part of the content of the bug.h is repeated among all

The idea of the patch is to change all to and
keep Xen compilable with adding only minimal amount of changes:
1. It was added "#include " to ARM's "" as it
uses uint_{16,32}t in 'struct bug_frame'.
2. It was added '#define BUG_FRAME_STRUCT' which means that ARM hasn't
been switched to generic
The following changes were made:
* make GENERIC_BUG_FRAME mandatory for ARM
* As do_bug_frame() returns -EINVAL in case something goes wrong
otherwise id of bug frame. Thereby 'if' cases where do_bug_frame() was
updated to check if the returned value is less than 0
* Switch ARM's implementation
The following defines BUG_DISP_WIDTH, BUG_LINE_LO_WIDTH,
BUG_LINE_HI_WIDTH aren't used in ARM so could be purged
as unused.
