Certain drivers always need an 'emulator' specified in the XML (qemu and lxc
at least). Store this info in capabilities.

We will eventually use this to move default emulator handling out of
drivers and into domain_conf.*

Wraps __virExec with the VIR_EXEC_DAEMON flag. Waits on the intermediate
process to ensure we don't end up with any zombies, and differentiates between
original process errors and intermediate process errors.

Add support for parsing node device XML descriptions.

This will be used by PCI passthrough related functions to
obtain the PCI device address for a given node device.

Re-factor the code from networkEnableIpForwarding() into a
utility function in preparation for code which writes to
sysfs files.

* src/qemu_driver.c: Use virSetCloseExec and virSetNonBlock,
rather than qemuSet* functions.  Suggested by Daniel P. Berrange.
* src/util.c (virSetCloseExec): Publicize.
* src/util.h (virSetCloseExec): Declare
* src/libvirt_private.syms: Add virSetCloseExec.

* src/virterror.c (virStrerror): Remove "static".
* src/virterror_internal.h (virStrerror): Declare it.
* src/libvirt_private.syms: Add virStrerror;
