util: bitmap: Don't alloc overly large binary bitmaps
Optimize the virBitmap to array-of-char bitmap conversion by skipping trailing zero bytes. This also fixes a regression when requesting iothread information from a live VM since after commit 825df8c3158cfaf5f398418471f10f4ff3c3515a the bitmap returned from virProcessGetAffinity is too big to be formatted properly via RPC. A user would get the following error: error: Unable to get domain IOThreads information error: Unable to encode message payload Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1238589
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
