Rootless Support

[L1ghtmann]

Changes:

• Implemented necessary Makefile changes
• Set up dev installation in an after-stage::

State:

• Unknown
  • Will determine this once I begin work on diagnosing Cr4shed's empty log list issue

Other:

• Resolves Rootless support #22
  - Removed the local .dylib for the time being as it will have the same name regardless of the scheme and thus only one would be preset at a given time
  - If you have any ideas on how to best handle this, please let me know
  - Currently, I'm thinking they may just have to be stored in two separate directories or uploaded in a release as unique zips

Edit:
06/25 Updates:

• Example server/client appears to work in SpringBoard, but crashed with 'Failed to create server receive port: Permission denied' in various apps a handful of times until the device locked up during an sbreload
• After jailbreaking into safemode, removing the test tweak, and rejailbreaking + reinstalling the tweak, apps seem to work fine
• Dare I say all is well with MRYIPC?

12/29 Updates:

• As described in the paired Cr4shed pr, something appears to be causing system instability
  • I have a feeling this is something with MRYIPC as I did encounter troubles in my initial 06/25 tests at one point also related to sbreload
  • Not familiar at all with xpc/mach, so not sure how well I'll be able to diagnose and fix that, but we'll see ....
