Richard Purdie 4fbb862cdc bitbake: siggen: Clean up task reference formats
Currently siggen uses the format "<filename>.<taskname>" for referencing tasks
whilst runqueue uses "<filename>:<taskname>". This converts to use ":" as the
separator everywhere.

This is an API breaking change since the cache is affected, as are siginfo files
and any custom signature handlers such as those in OE-Core.

Ultimately this will let us clean up and the accessor functions from runqueue,
removing all the ".rsplit(".", 1)[0]" type code currently all over the place.
Once a standard is used everwhere we can update the code over time to be more
optimal.

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.
