We need to restrict *all* the control fds that qemu opens. Looking in
/proc/PID/fd shows there are many; their allocation seems scattered
throughout Xen support code in qemu.
We must postpone the restrict call until roughly the same time as qemu
changes its uid, chroots (if applicable), and so on
This just-amended series provides necessary support for running qemu
as a Xen device model without power equivalent to root. In
particular, it makes -xen-domid-restrict effective.
Compared to v6, it fixes some minor checkpatch, style and portability
issues. Sorry for the earlier troubled submiss

Xen libraries in 4.10 include a new xentoolcore library. This
contains the xentoolcore_restrict_all function which we are about to
want to use.

xc_interface_open etc. is not going to work if we have dropped
privilege, but xendevicemodel_shutdown will if everything is new
enough.
xendevicemodel_shutdown is only availabe in Xen 4.10 and later, so
provide a stub for earlier versions.

This makes it much easier to find a particular thing in config.log.
The information may be lacking in other shells, resulting in harmless
empty output. (This is why we don't use the proper ${FUNCNAME[*]}
array syntax - other shells will choke on that.)
The extra output is only printed if configu

If you pass scripts/get_maintainer.pl the name of a FIFO or other
exciting object (/dev/stdin, for example), it would falsely print
"file not found". Instead: stat the object rather than using -f so
that we do not mind if the object is not a file; and print the errno
value in the error message.

This avoids checkpatch misparsing (as statements) long function
definitions or declarations, which sometimes start with constructs
like this:

This allows the caller to specify a uid and gid to use, even if there
is no corresponding password entry. This will be useful in certain
Xen configurations.
We don't support just -runas because: (i) deprivileging without
calling setgroups would be ineffective (ii) given only a uid we don't
know
