threads: check for failure to set thread-local value
We had a memory leak on a very arcane OOM situation (unlikely to ever hit in practice, but who knows if libvirt.so would ever be linked into some other program that exhausts all thread-local storage keys?). I found it by code inspection, while analyzing a valgrind report generated by Alex Jia. * src/util/threads.h (virThreadLocalSet): Alter signature. * src/util/threads-pthread.c (virThreadHelper): Reduce allocation lifetime. (virThreadLocalSet): Detect failure. * src/util/threads-win32.c (virThreadLocalSet): Likewise. (virCondWait): Fix caller. * src/util/virterror.c (virLastErrorObject): Likewise.
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.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
