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.
