Paul Barker 61e1b4136f archiver.bbclass: Add new mirror archiver mode
We define a new method of populating a source mirror using the archiver
bbclass instead of simply copying the contents of the downloads
directory. This allows the archiver features such as copyleft license
filtering and recipe type filtering to be used when preparing a source
mirror.

This new archiver mode is selected by setting `ARCHIVE_MODE[src]` to
'mirror'.

The source mirror mode can either be 'split' (default) or 'combined',
controlled by `ARCHIVER_MODE[mirror]`. Additionally, sources can be
excluded as needed by setting `ARCHIVER_MIRROR_EXCLUDE` to a list of
URI prefixes. These options are described in more detail in the new
entries in the header of archiver.bbclass.

New oeqa selftest cases are added to cover the mirror archiver mode.

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.
