[Libguestfs] [PATCH 0/4] common: Add a simple mini-library for handling qemu command and config files.



Currently we have an OCaml library for generating the qemu command
line (used only by ‘virt-v2v -o qemu’).  However we also generate a
qemu command line in ‘lib/launch-direct.c’, and we might in future
need to generate a ‘-readconfig’-compatible configuration file if we
want to go beyond 10,000 drives for scalability testing.

Therefore this patch series reimplements the qemu command line code as
a small C library (common/qemuopts), extends it to support qemu config
files, and then reimplements both ‘lib/launch-direct.c’ and ‘virt-v2v
-o qemu’ to use it.

It also fixes a few bugs.  In particular we don't properly comma-quote
qemu parameters in multiple places.  This fixes all of those places
properly.

It also drops support for ‘./configure --with-qemu-options’ which is
broken (see commit message).

Rich.
