[Toaster] 7414 example for layer 'meta', is it really a layer?

[Lerner, Dave]

The 7414 bug states:
"
For example, instead of 
  /home/user/_poky_master.toaster_cloned/meta/conf/bitbake.conf
only
  meta/conf/bitbake.conf
"

So for example for a 'Yocto Project master' project selection with 5 layers 
* the 3 default: oe-embedded, meta-yocto, meta-yocto-bsp 
* and two added: meta-oe and meta-games, 
then for variable "COMBINED_FEATURES", the path is exactly as in your example, but there is no layer named 'meta' is not in the layer table.  

Is 'meta' a layer that is 'built-in'?

I'm using a string matching algorithm on the directory name to locate the layer in a local path string, layer name length >=4, matching either '/' + layer name or '/_' + layer name, with the layer names sorted descending so that longest layer names match first.
