Fast signing support in jtool2

Postby flickz » Sat Jul 18, 2020 10:42 pm

When working on large Apple projects, code signing time can take 4+ seconds, hurting the incremental build time. It would be great if jtool2 supported fast signing with two modes:
- For general-purpose signing, parallelized hashing that makes use of all cores
- For debuggers, signing that just fills each hash with 0's, and injects the entitlements as usual (since debuggers seem to be more permissive)

I would fork codesign.cpp in Apple's open-source repo and do it myself, but those OSS projects are kind of a mess. Thoughts?
