Make the following improvements to the SDK update process:
* Use a manifest file with sha256sums to track files other than sstate
and metadata that we need to update - e.g. conf files. This allows us
to handle where files such as auto.conf may or may not be present,
as well as the configuration changing without affecting task signatures
- we still want the config files copied in that case rather than it
saying nothing needs to be done.
* Write the SSTATE_MIRRORS_append to site.conf rather than local.conf
so that local.conf remains static (since we don't want to trigger an
update every time). Also, If there is an SSTATE_MIRRORS value already
set in the configuration we can skip this and assume it contains the
needed packages.
* Allow the update process to be run in any directory, don't assume
we're already at the base of the SDK
* Where practical, fetch remote files into a temporary location and
then move them to the desired location at the end, to avoid a
failed update leaving the SDK in a broken state.
* Update all installed do_populate_sysroot / do_packagedata tasks
instead of using the SDK targets. This ensures any item installed
through dependencies after installation (e.g. when running
"devtool build") won't go stale.

Add a variable SDK_INCLUDE_PKGDATA which you can set to "1" to include
pkgdata for all recipes in the world target. There are a couple of uses
for this:
1) If you use "devtool add" to add a recipe that builds something which
depends on anything in world, the dependency can then be correctly
mapped to the recipe providing it and that recipe can be added to
DEPENDS, since we have the pkg-config and shared library dependency
data within pkgdata.
2) You'll be able to search for these recipes and any files they
package for the target with "devtool search" since that also uses
pkgdata
This of course assumes you've tailored world through EXCLUDE_FROM_WORLD
to only include recipes you'd want built in your distro, but I think
that's a reasonable assumption; failing that there is a
WORLD_PKGDATA_EXCLUDE variable that you can set to exclude any recipes
you don't want.
Note that this patch relies on functionality implemented in a recent
BitBake patch and will not work without it.

eabeb26335b1a4eb1e68218160dbdbe8fdf36272 where we lost the task
dependency on packages in TOOLCHAIN_HOST_TASK (such as
meta-environment-extsdk-${MACHINE}) which led to errors about missing

Create a separate task where we can just have the recursive dependencies

the image contents). This avoids us recursing into dependencies from
buildtools and getting a bunch of nativesdk stuff, for example.

Right now, the locked task hashes list for the extensible SDK locks
down only the sstate tasks.
Whilst asthetically pleasing, this gives two problems:
* Half the task are left floating meaning checksum mismatches
are a pain to debug
* The later code which copies relavent data files out the sstate
cache can't use any of this data.
This patch modifies things so all the checksums are listed in the locked
file. An exclusion of tasks probably makes more sense for the library
function rather than an allowed list.
The only sstate task being deliberaly excluded here was do_package
so add in a function to explictly exclude those sstate object files.
The net result of this that siginfo files for all tasks are included in
the SDK, which means commands like "bitbake -S printdiff" now function.

In order to prepare the build system within the extensible SDK, we
actually go ahead and build the targets specified by SDK_TARGETS (by
default the image the SDK was built for). Assuming that's an image, we
don't actually need to build the image itself - we just need to have
everything done up to the point before building the image, so that we
have everything needed in the sysroot.
In order to do this, create temporary bbappends for each of the targets
in the workspace layer that stub out do_rootfs and related tasks if they
exist. This is a little bit of a hack but is the least intrusive fix at
this point. To make things a bit tidier, I have split out the
preparation commands into a separate script so we can run that in the
appropriate environment rather than all the commands separately.

bash is happy to expand wildcards in the target of a redirection, but
bash running in POSIX sh mode won't (although it apparently does work on

Copy the contents of local.conf under TOPDIR into the final generated
local.conf. In this way, custom settings are also made into the final
local.conf like IMAGE_INSTALL, DISTRO_FEATURES, VIRTUAL-RUNTIME_xxx,
etc. Comments and blank lines are filtered out.
Before this change, installing extensible SDK would usually report failure
when preparing the build system if the user has custom configuration for
DISTRO_FEATURES in local.conf. Also, items in IMAGE_INSTALL_append in
local.conf also don't get built correctly.
This patch solves the above problem by making use of bb.utils.edit_metadata.
In addition, we check to avoid any setting that might lead to host paths
bleeding into the SDK's configuration. Basically, variables with values
starting with '/' are removed. A whitelist mechanism is introduced so that
users could specify variables that should not be ignored. The name of the
whitelist is SDK_LOCAL_CONF_WHITELIST.
The SDK_META_CONF_WHITELIST is removed as it's of no use after this
change.
SDK_LOCAL_CONF_BLACKLIST can be used to prevent copying specific
variable settings to the extensible SDK's local.conf; the default is to
exclude PRSERV_HOST (since this is likely to be internal). Similarly,
SDK_INHERIT_BLACKLIST to forbit local.conf in SDK to inherit certain
classes such as 'buildhistory' or 'icecc' that would not normally make
sense in an SDK environment.

This bbclass will create an SDK with a copy of bitbake and the metadata
and sstate for the target specified for the task. The idea is to let
"system" developers both work on applications and then test adding them
to an image without having to switch between workspaces or having to
download separate items.
Rather than running bitbake directly however, the primary way of running
builds within the extensible SDK is to use the "devtool" command. The
rest of the build system is fixed via locked shared state signatures,
and thus only the recipes you have added get built.
