Based of xerub's patchfinder64, adds various patches which should work across a variety of versions.

Patches written by myself are included here. These include patches from async_wake-fun and from unc0ver

This fork includes a testing portion, allowing us to confirm that the results returned from the patchfinder are valid.

To run the tests, you must do the following:

1. Run ./fetch_kerncaches, or run python ./fetch_kerncaches. Please note this will download 13 iOS versions, and extract and decompress the kernelcaches. You can change which versions of iOS are to be downloaded in the file.
2. Run make patchfinder64
3. Run python test_versions.py

This will return what version have their patchfinders working correctly, and will tell you which functions are not finding the correct values (PF = Patch Finder, AS = Actual Symbol).
