Make "fullgray" dithering work properly, to force greyscale rendering. To use
it, just call caca_set_dither_color(d, "fullgray") on the dither object.

Continue the libcaca/libcucul merge. Source and binary compatibility
are almost there.

Starting refactoring to get rid of libcucul. The initial reason for the
split is rendered moot by the plugin system: when enabled, binaries do
not link directly with libX11 or libGL. I hope this is a step towards
more consisteny and clarity.

far better for error checking.

* Changed most of the long ints in the API into C99 types. WARNING: this
completely breaks compatibility with previous versions of libcaca on
64-bit systems.

* Changed most "unsigned char" variables into "uint8_t", including in
prototypes. As they are equivalent, this does not break the ABI.

* Remove #include <stdint.h> etc. from "common.h". Instead, make sure that
<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.

* Add cucul_get_dither_brightness(), _gamma() and _contrast(). There is no
reason to keep a copy of them in the calling program.
* Deprecate cucul_set_dither_invert(). Inverting a dither's colours is now
done by setting a negative gamma value.

* Changed cucul_putchar's prototype so that it accepts a 32-bit unsigned
int which shall be used as an UTF-32 character. We do not have any casting
problems due to the signedness of chars because all characters were
ASCII (ie. <= 0x7f) beforehands.
