[libvirt] [PATCH] openvz_conf.c: remove dead store to "p"; use strchrnul

[Jim Meyering]

I may separate this into two commits.
Currently we can't use the part that adds the strchrnul use,
since gnulib's module lists its license as LGPL, which
means LGPLv3+, and that conflicts with libvirt's LGPLv2+ requirement.
However, since strchrnul is derived from glibc, it should be easy
to adjust that.  I've asked the maintainer of that module on the
bug-gnulib list.  We'll see later today when the US wakes up.

Subject: [PATCH] openvz_conf.c: remove dead store to "p"; use strchrnul

* src/openvz_conf.c (openvzReadNetworkConf): Replace open-coded
while loop with equivalent use of strchrnul.
* bootstrap (modules): Add strchrnul.
