Ulf Magnusson db20fe6f0a bitbake: fetch2/svn: Fix SVN repository concurrent update race
The ${DL_DIR}/svn directory is used by BitBake to keep checked-out SVN
repositories from which tarballs are generated. These repositories were
protected from concurrent update with a lock on the tarballs. However,
the tarballs are specific to the SRCREV and module checked out (many
tarballs can come from the same repository), meaning a repository could
be modified concurrently if two recipes checked out two different
SRCREVs or modules from it in parallel. This caused errors like the
following:

ERROR: Fetcher failure: Fetch command failed with exit code 1, output:
svn: E155004: Run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)
svn: E155004: Working copy '/home/foo/downloads/svn/repo/trunk' locked.
svn: E155004: '/home/foo/downloads/svn/repo/trunk' is already locked.

Fix it by adding a per-repository lock that's independent of the module
and SRCREV.

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.
