Chris Lalancette 21adf03c2d Qemu Monitor API entry point.
Add the library entry point for the new virDomainQemuMonitorCommand()
entry point.  Because this is not part of the "normal" libvirt API,
it gets its own header file, library file, and will eventually
get its own over-the-wire protocol later in the series.

Changes since v1:
 - Go back to using the virDriver table for qemuDomainMonitorCommand, due to
   linking issues
 - Added versioning information to the libvirt-qemu.so

Changes since v2:
 - None

Changes since v3:
 - Add LGPL header to libvirt-qemu.c
 - Make virLibConnError and virLibDomainError macros instead of function calls

Changes since v4:
 - Move exported symbols to libvirt_qemu.syms

    Explanation about the how multi-version support
    for VirtualBox libvirt driver is implemented.

Since VirtualBox adds multiple new features for each release, it is but
natural that the C API which VirtualBox exposes is volatile across
versions and thus needs a good mechanism to handle multiple versions
during runtime. The solution was something like this:

Firstly the file structure is as below:

vbox_CAPI_v2_2.h
vbox_XPCOMCGlue.h
vbox_XPCOMCGlue.c
These files are C API/glue code files directly taken from the
VirtualBox OSE source and is needed for C API to work as expected.

vbox_driver.h
vbox_driver.c
These files have the main logic for registering the virtualbox driver
with libvirt.

vbox_V2_2.c
The file which has version dependent changes and includes the template
file for given below for all of its functionality.

vbox_tmpl.c
The file where all the real driver implementation code exists.

Now there would be a vbox_V*.c file (for eg: vbox_V2_2.c for V2.2) for
each major virtualbox version which would do some preprocessor magic
and include the template file (vbox_tmpl.c) in it for the functionality
it offers.
