configure gets 2 new options:
--enable-neon / --enable-neon-rtcd
the NEON modules are split to their own convenience lib and built with
auto-detected flags if none are given via CFLAGS.
the /proc/cpuinfo check will only be used for armv7 targets whose
toolchain does not enable NEON by default or didn't have NEON forced by
the CFLAGS from the environment.

TEST_AND_ADD_CFLAGS tests flags independently from AM_CFLAGS. The lack
of -Wformat may cause -Wformat-* checks to fail (gcc 4.9), though in the
end they would have succeeded with -Wall present.

and make it the default if available. this limits symbol visibility to
those marked with WEBP_EXTERN.

It can be used to test if given pair of animated images (GIF and/or

Visible speed-up, thanks to pshufb and pabsw and psignw use.
had to tweak configure.ac to make "smmintri.h" presence correctly
detected (we need to set the CPPFLAGS instead of the CFLAGS!)

fixes thread support detection in e.g., cross-compiles/mingw installs
without libpthread, the behavior is unchanged in mingw installs with
libpthread. in the latter case although libpthread is detected the
windows api (_beginthreadex) path is being used.

possibly other cross-compiles; avoids misusing -mavx2/-msse2 in these
cases by checking the usability of the associated intrinsics header
files.

this defines WORDS_BIGENDIAN, replacing uses of

this change has the side-effect of using directory names in the
include, silencing a lint warning.
