Title: adapting new-error-handling in pygit2

New error handling in libgit2 0.17 is now done the posix way. One error code for each expected failure,
and a generic error code for all critical ones. The last critical error can be accessed by giterr_last().
It returns a pointer to the global error struct. For more information see docs/error-handling.md in libgit2.
