[PATCHv3] Script to highlight state of patches in tree

[Miguel A. Flores Silverio]

The intent for this script is to make easier patch management
and documentation.

Signed-off-by: Miguel Flores Silverio <floresmigu3l(a)gmail.com&gt;

* PATCHv1
  - use colors to highlight the patch location
  - different flags to list patches in PatchList.txt kernl.spec

* PATCHv2
  - Fix: match flags with functionality accordignly
  - Uses characters instead of colors to identify each patch
    not all consoles support color.
  - adds extra flag to show patches that are prsent in the tree but
    not recorded in PatchList.txt nor kernel.spec
* PATCHv3
  - Fix: Logic missing condition for patches in tree recorded in
    PatchList.txt but missing in kernel.spec
  - Add: Option for patches present in the tree but only recorded in
    PatchList.txt
