[libvirt] [PATCH v2 0/4] Resolved CHECKED_RETURN errors found by Coverity

Rather then further muddy the waters of the previous patch series, this is a fresh patch series. I added one patch to this since the code was in the same general area as the virBufferTrim patch. Differences in v2 rpc: Updated the commit message to include why only putting out a VIR_WARN. The code did not change. The original patch: https://www.redhat.com/archives/libvir-list/2013-January/msg00103.html tools: Rework the patch to check the virBufferTrim() status return. Added virBufferError() status check after virBufferAddLit() to match the similar check after virBufferAddChar(). The original patch: https://www.redhat.com/archives/libvir-list/2013-January/msg00118.html xen: Resend of the v2 patch to keep in the same series: https://www.redhat.com/archives/libvir-list/2013-January/msg00473.html which was the replacement for: https://www.redhat.com/archives/libvir-list/2013-January/msg00114.html util: (new) The coverity error was NEGATIVE_RETURNS. The complaint being the potential to call memset() with a negative indent value. Since virBufferGetIndent() will check and fail on buf->error, I removed that check from virBufferAdd() and used the -1 return as the way to exit.
