Util now, only paths added for current project are removed to avoid PATH growing unnecessarily. This is to handle the case of sourcing the init script into different build directories. However, if we source the init script from different projects into different build directories, the paths added by previous projects are not cleaned up. To avoid this, we record the paths added into OE_ADDED_PATHS, and remove it in the next sourcing. The OE_ADDED_PATHS variable is exported mainly for the two reasons: 1. users can clearly see it in the `env' command's output. 2. if the prefixed PATH is carried into the subprocess (e.g., a subshell), so should this OE_ADDED_PATHS variable that prefixes it. Note that the paths, "$OEROOT/scripts:$BITBAKEDIR/bin:", are added as a whole. A previous commit, "oe-buildenv-internal: Add paths to $PATH individually", made the change to treat these two paths separately, the reason was not "assuming the path to the scripts directory always is in $PATH directly before the bitbake directory". But this is exactly the effect of the codes. I see no reason why we should complicate things.
