[PATCHv3 0/5] Support symbolic links in paths in PSEUDO_IGNORE_PATHS

["Peter Kjellerstedt" <peter.kjellerstedt@axis.com>]

The changes in this patch series aim to rectify a problem with pseudo
and its support for ignoring paths. When pseudo compares a path to the
paths specified in PSEUDO_IGNORE_PATHS, it uses a path that has been
canonicalized. However, it does not canonicalize the paths in
PSEUDO_IGNORE_PATHS itself and unless they are canonicalized, they
will not match as intended. Thus the paths in PSEUDO_IGNORE_PATHS
needs to be canonicalized. These patches do that by adding a new
function oe.path.canonicalize(), which is then used when passing 
${PSEUDO_IGNORE_PATHS} to pseudo.

There is also one patch that adds two patches to pseudo to clean up
pseudo_client_ignore_path_chroot(), and they also plug a memory leak.
The patches were brought about as I initially intended to do the
canonicalization in pseudo itself in this function.

I have not tested the change to wic as we do not use it, though I do
not expect it to be problematic.

PATCHv2: 
  * Removed some unrelated changes in the second patch.
PATCHv3: 
  * Handle an edge case in pseudo_client_ignore_path_chroot() in case
    PSEUDO_IGNORE_PATHS contains ",," or leading/trailing commas.
  * Introduce oe.path.canonicalize() and use it instead of adding
    PSEUDO_IGNORE_REAL_PATHS as was previously done.
  * Add similar code to wic.
