Remove HAVE_LIMITS_H
...
The `<limits.h>` header file is part of the standard C89 headers [1] and
on current systems there is no need to manually check if header is
present anymore.
Since the libgd requires at least C89 or greater, the `HAVE_LIMITS_H`
symbol defined by Autoconf in configure.ac [2], and Cmake build system
files can be removed and simplifed.

clean up trailing whitespace/newlines
...
This is preparation for adding some linting checks for new commits from
people. Shouldn't be any functional changes here (tests still pass!).

configure/cmake: unify header checks and config.h generation
...
Rather than hand maintain config.h.cmake (which is already out of date),
re-use the autogenerated config.h from autoheader.

Small code cleanup.
...
Removed non-exported prototypes from gd.h. Where possible, made the
functions static and moved the rest of the prototypes to gd_intern.h.
Also removed redundant macros MIN/MAX macros from gd_interpolation.c
(since they're also defined in gd_intern.h) and tidied the formatting
a little.

Added a new Gaussian blur function.
...
gdImageCopyGaussianBlurred() returns a blurred copy of its argument.
Blurring is done in two passes to take advantage of the Gaussian
function's separability for. This makes the algorithm much faster
than single-pass implementations, especially for larger radii.
This change also adds documentation for the new function and the
existing blur (gdImageGaussianBlur()).
