Richard Purdie 58530c6e48 bitbake: data_smart: Preserve history when renaming variables
Currently when a variable is renamed, all the variable history is lost.
This makes it hard for users to understand/debug where values came from.

Improve the code so that history is preserved across renamed variables.

(Expanded variable key names are a special case of variable renaming)

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
