libuEv v1.2.2

Minor bugfix release.

Changes

• The ifdef STATIC in the Makefile has been removed. Now both the
  .a and .so libraries are built. The user may then select what to
  install. This is a change for convenience when using libuEv from
  a GNU Configure & Build based project.

Fixes

• Fix odd data ordering issue on Debian Jessie in new uev_private_t
• Fix issue #6: Segfault when stopping timer before calling uev_exit()
