[oe][OE-core][Patch 0/2] implement applying patches from a directory

[Max Krummenacher <max.oss.09@gmail.com>]

The current developer manual [1] specifies that patches that are
part of a directory which is given in SRC_URI are applied by
the do_patch task. However that is not implemented in the
current code.

This patchset implements that, but deviates from what is
documented. If the patches are applied I will send a patch
for the documentation changing the relevant part to:

```
If you have a directory full of patch files and you want to
apply them all you can add the directory to SRC_URI and add
the "apply=yes" parameter. This will apply ALL files in the
directiory, including files in subdirectories.
The patches will be applied sorted by their filename. Files
from subdirectories will be sorted into the list at the
position given by the subdirectory name.

   SRC_URI = " \
       git://path_to_repo/some_package \
       file://path_to_lots_of_patch_files;apply=yes \
       "

In the previous example all the files in the directory holding
the patch files would be applied as a patch.
```
