<cucul.h> will provide the C99 types, even if libcaca has been installed.
  * Rename what's left of "common.h" to "stubs.h".
  * Remove all references to erroneous <inttypes.h> from source files.

due to spaces.

* Added a few additional character pairs of the left/right rotations.
  * Added missing errno sets.

cucul_stretch_* to avoid long function names. And the pairwise rotations

* Updated test/text to show what the wide rotations now do.

suck massively for now.

* Renamed cucul_rotate into cucul_rotate_180.
  * Deprecated cucul_rotate and fix examples accordingly.

  * Added a case to test/fullwidth.c for cucul_blit and fullwidth chars.

* Made these functions fullwidth-aware.

* Renamed canvas handle variables from "c" to "cv". Eh ouais mon gros.
