commit 36cdad13cd5038f10aa9fc99c682d8987fab45d5
Author: Richard Purdie <richard.purdie at linuxfoundation.org>

    package: Allow parallel processing of shlib analysis
    
    This function is a bit more invasive to add parallelism to but
    allows the shlibs analysis to happen in multiple threads. In order
    to return values correctly/safely the data types needed tweaking
    to avoid lists and use immutable objects.
