Matthias Bolte 0821ea6b3c esx: Disable libcurl's use of signals to fix a segfault 
libcurl uses a SIGALRM in combination with sigsetjmp/siglongjmp to be
able to abort a DNS lookup when it takes too long. The problem with this
in a multi-threaded application is that the signal handler for SIGALRM
and the call to siglongjmp can be executed on a thread that is different
from the one that initially did the SIGALRM setup and the call to
sigsetjmp. In the reported case this triggered a segfault.

Disable libcurl's use of signals to avoid this situation. This has the
disadvantage of losing the ability to abort synchronous DNS lookups which
might result in libcurl getting stuck in a DNS lookup in the worst case.
When libcurl was build with an asynchronous DNS backend such as c-ares
then there is no problem because the timeout mechanism works without
signals here anyway.

Reported by Benjamin Wang.

         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.
