codeparser: Fix to better catch all getVar references

Currently if you do localdata.getVar, the code parser simply ignores
the references. Change the code to use endswith() to catch more of the
references. These names are probably unique enough to get away with this.

Bump the cache version to ensure things get updated.

persist_data: Avoid fsync() calls

If the power were to fail, it doesn't matter to us much if the data
makes it to disk or not, we'd have other problems. However an fsync()
call on a multi build autobuilder is painful so lets avoid them.

This is particularly true in this case if a timeout causes a reconnect
during a build.

world-image: add extra target

* similar to world target, but collects all PACKAGES
* recipes marked with EXCLUDE_FROM_WORLD are excluded from world as well
  as world-image
* recipes marked with EXCLUDE_FROM_WORLD_IMAGE are excluded completely
  from world-image, sometimes you can build 2 recipes in same sysroot,
  but cannot install them in the same image
* PACKAGES listed in EXCLUDE_PACKAGES_FROM_WORLD_IMAGE are also
  excluded. You can remove e.g. ${PN}-dbg, but keep all other PACKAGES.
