Add support for file descriptor sets by converting some of the
command line parameters to use /dev/fdset/%d if -add-fd is found
to be supported by QEMU. For those devices libvirt now open()s
the device to obtain the file descriptor and 'transfers' the
fd using virCommand.
For the following fragments of domain XML
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/var/lib/libvirt/images/fc14-x86_64.img'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
<serial type='dev'>
<source path='/dev/ttyS0'/>
<target port='0'/>
</serial>
<serial type='pipe'>
<source path='/tmp/testpipe'/>
<target port='1'/>
</serial>
libvirt now creates the following parts for the QEMU command line:
old: -drive file=/var/lib/libvirt/images/fc14-x86_64.img,if=none,id=drive-ide0-0-0,format=raw
new: -add-fd set=1,fd=23,opaque=RDONLY:/var/lib/libvirt/images/fc14-x86_64.img
-add-fd set=1,fd=24,opaque=RDWR:/var/lib/libvirt/images/fc14-x86_64.img
-drive file=/dev/fdset/1,if=none,id=drive-ide0-0-0,format=raw
old: -chardev tty,id=charserial0,path=/dev/ttyS0
new: -add-fd set=1,fd=30,opaque=/dev/ttyS0
-chardev tty,id=charserial0,path=/dev/fdset/1
old: -chardev pipe,id=charserial1,path=/tmp/testpipe
new: -add-fd set=2,fd=32,opaque=/tmp/testpipe
-chardev pipe,id=charserial1,path=/dev/fdset/2

v2->v3:
- Use an unsigned int for remembering the last used fdset
v1->v2:
- Addressed many of Eric's comment; many changes, though
- virBitmap holds used file descriptor sets; it's attached to
QEMU private domain structure
- persisting and parsing the fdset in the virDomainDeviceInfo XML
- rebuilding the fdset bitmap upon libvirt start and after parsing
the virDomainDeviceInfo XML
