This patch is just adding a single header, but because it also modifies
all the C files to add the #include, it was made as a patch on its own to
ease review.

It is generally not a good idea to have an API with a high number of
functions because it adds complexity for user and for maintainability,
so both function have been "merged" into a single RFlipImage with
a parameter to specify what flip is expected.
As a bonus, the function can perform both flips at once if wanted.

As it does not cost anything in the current code to not add this channel,
it is then probably a good idea to keep the output image with the same
format as the input image, this avoid wasting +33% of memory for something
that may be at best unused and at worst will induce extra cost when
manipulating the image.

Instead of calling all variables with variants of 'image', changed
the name to reflect what image it is about for clarity.

With a set of images i was able to detect that
the flip functions was shifting the image by 1px.
The 90 and 270 degrees rotation were not working as
the functions were also mirroring the img.
The patch is also fixing the C style based on checkpatch.
