Current requirements pull in too-new pygit2

[xenithorb]

On Fedora 25 using your virutalenv instructions, I ran into:

  In file included from src/blob.h:34:0,
                   from src/blob.c:30:
  src/types.h:36:2: error: #error You need a compatible libgit2 version (v0.25.x)
   #error You need a compatible libgit2 version (v0.25.x)
    ^~~~~
  error: command 'gcc' failed with exit status 1

The solution was to clamp pygit2 <= 0.24.2 which was the last version that supports what libgit2 is currently in fedora at the time of my writing this: libgit2-devel-0.24.6-1.fc25.x86_64 it might resolve itself with time, but perhaps you should consider version locking to something known to be compatible.

The issue is that the pygit2 x.y release must match the libgit2 x.y release, so I can't quite enforce a pygit2 version, since it depends on the libgit2 one that is installed on your machine (outside of the venv).
