We rely on pkg-config first, because that is the traditional way to
query configs and because that's how the MagickWand API suggests to do.

It looks like that the function 'MagickGetImagePixels' is part of
the "deprecate.h" header, at least in ImageMagick 6.8.8. As it is not
used in WRaster's code, it is safer to actually check for 'NewMagickWand'
that is being used and which is not yet deprecated.

Took the opportunity to expand the WM_LIB_CHECK macro because it is not
suited for the case where compilation flags can be queried but was meant
for the case when they have to be guessed

This patch is adding support for google webp image format, if you
don't know it a quick recap is to say that according to their tests
they claim it is better than png and jpeg.

There are a number of steps in the library check procedure that are a bit
repetitive, and have been placed into the macro WM_LIB_CHECK to make the
code simpler to write.

The function can have a wider use, so moved then to a more neutral place
and gave them more generic names.

The original check was not compliant with autoconf's syntax, did not
have a very good behaviour for user and was not easy to make evolve.
The new macro:
- uses as much as possible autoconf macros for portability and code
consistency;
- provides a consistent behaviour on yes/no/auto (if user explicitly
enables support, do not silently disable if not found; if library is found
but not the header, complain to let user install it or explicitly disable
support);
- makes uses of shell functions to keep generated configure smaller by
sharing reusable stuff;
- uses an automake conditional to avoid compiling the file is support is
not enabled

As reported by Nicolas (nhs), compilation of wrlib is broken when
switching to gif_lib v5.
The API of gif_lib has known little change to provide thread-safe usage,
so we now detect this in configure and and use the functions as appropriate
in gif.c

The use of the conditionals provided by autotools provides a better result
as they avoid unnecessary compilation.

It includes a fixes from a problem found by Amadeusz S-B³awiñski, because-A
the function 'wm_fn_imgfmt_try_link' modified the variable LDFLAGS
instead of LIBS.
