If you want to extend QEMU, then send proper patches. Adding random C files to
the build is unacceptable.

Changes in v2:
* Rebase on 1c8a881daaca6fe0646a425b0970fb3ad25f6732 from master.
* Multiple documentation fixes and clarifications.
* Fixed a couple of bugs when freeing memory.
* Actually call 'backdoor_fini' in user mode when exiting.
* Try to auto-detect the backdoor device in the example guest library when
running a full-system linux.
* Rewrite code to read and write into the control channel in softmmu mode,
making it much clearer and leaving endianness handling up to the
user-provided
backdoor callbacks.
