[PATCH] Add safe wrapper around waitpid which deals with EINTR correctly.
As Eric Blake noted in:
https://www.redhat.com/archives/libguestfs/2016-April/msg00154.html
libguestfs doesn't correctly handle the case where waitpid receives a
SIGCHLD signal and the main program has registered a non-restartable
signal handler.
In this case waitpid would return -EINTR and we would print an error,
but actually we should retry this case.
This adds two new internal functions,

[PATCH v2 0/4] Experimental User-Mode Linux backend.
v1 was here:
https://www.redhat.com/archives/libguestfs/2013-August/msg00005.html
This now works, to some extent. The main problem now is that devices
are named /dev/ubd[a-] which of course confuses everything. I'm
thinking it may be easier to add a udev rule to rename them.

[PATCH 0/4] Not quite working User-Mode Linux backend.
This is a User-Mode Linux backend for libguestfs. You can select it
by doing:
export LIBGUESTFS_BACKEND=uml
export LIBGUESTFS_QEMU=/path/to/vmlinux
Note we're reusing the 'qemu' variable in the handle for convenience.
QEmu is not involved when using the UML backend.
This almost works. UML itself crashes when the daemon tries to
connect to the serial port. I suspect it's

[PATCH 0/2] Don't use snapshot=on
QEMU upstream has broken snapshot=on ... again.
These two patches stop using it entirely. Instead we run
'qemu-img create' to create overlay disks as required.
Note that the libvirt and UML backends were already doing this: The
libvirt backend because <transient/> has never worked, and the UML
backend was running uml_mkcow because the UML-equivalent syntax of
snapshot=on was

[PATCH 0/2] Change guestfs__*
libguestfs has used double and triple underscores in identifiers.
These aren't valid for global names in C++.
(http://stackoverflow.com/a/228797)
These large but completely mechanical patches change the illegal
identifiers to legal ones.
