dragonffi

Rebased on LLVM13.

All the work has mainly been done by @kamino , many thanks to him!

Add the LazyJITWrappers option in the Python bindings

Includes support for compiling C++ code and call it from extern "C" functions.

Also speeds up the cdef function by lazily compiling the FFI wrappers on first usage!

• Support saving errno/LastError for system functions (closes #62)
• Based on Clang/LLVM 11.1

• mainly rebase DragonFFI on Clang/LLVM 11.0.0

• Python: add support to create a pointer with an arbitrary value

• Fix Python 2.7mu wheel
• Properly test Python wheels

• Fix issue with alias functions

Basically the same as 0.6.0-rc0:

Add API to add custom symbols
Add API to get base address of dlopen'ed libraries
Python: fix creation of functions by their type and absolute address
Python: allow creation of pointers with an arbitrary value
