GDB Refactor [2/N]: move some modules to lib/

[gsingh93]

version.py, which.py, functions.py, tips.py, and funcparser.py already didn't have any dependency on GDB, so these could just be copied to lib/. Also fixed the .gitignore to not exclude pwndbg/lib/.

What is pwndbg/lib/functions.py used for? It's too large.

[gsingh93]

I have no clue, for now my goal is just to move things into the right directories without breaking things. Once that's done, the next step will be to write unit tests, add types, refactor poorly designed code, etc.

[disconnect3d]

shouldnt this file be moved instead of added? weird

It is used to enhance display of function arguments of known functions; I think it may have been generated from manpages or some other source

[syheliel]

It uses PyCParser and generated by pwndbg.lib.funcparser.ExtractFuncDeclFromSource
