[libvirt] [PATCH V4 0/5] support sending sysrq key

[Chunyan Liu]

xend/libxl support sending sysrq key to guest kernel but not support
sending any key sequence as virDomainSendKey is expected to do. To
add equivalant sysrq functionality in libvirt for xen/libxl, add a new
virDomainSendSysrq API and add related codes to virsh, remote driver,
xen/libxl driver.


Changes to V3:
  * fix some memory leak

Not change:
  virDomainSendSysrq parameter still keeps "char key" rather than "enum
  key", main reason to keep it because: sysrq key is different to different
  kinds of guests, xen hypervisor doesn't know the correct enum <-> letter
  mapping towards different guests, it just sends the key blindly to guests.
