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.

defines HAVE_BUILTIN_BSWAP16/32/64
updated endian_inl.h to have a non-configure fallback for gcc and clang
BSwap16() now uses __builtin_bswap16 if available

possibly other cross-compiles; avoids misusing -mavx2/-msse2 in these
cases by checking the usability of the associated intrinsics header
files.
iosbuild.sh has been broken since at least:

forces aligned memory reads (via memcpy) in the VP8 bit reader, useful
for platforms that don't support unaligned loads.

this defines WORDS_BIGENDIAN, replacing uses of
__BIG_ENDIAN__/__BYTE_ORDER__ with it
+ fixes lossless BGRA output with big-endian toolchains
that do not define __BIG_ENDIAN__ (codesourcery mips gcc)
Change-Id: Ieaccd623292d235343b5e34b7a720fc251c432d7
this change has the side-effect of using directory names in the
include, silencing a lint warning.

+ add a WEBP_HAVE_SSE2 to dsp.h
not all 32-bit toolchain configurations will have sse2 enabled by
default
Change-Id: I7c675e511581f93cf55c79f960fa7efa2df4987e
this is used to set WEBP_USE_AVX2 in files where the build flag won't be
used, i.e., dsp/enc.c, which enables VP8EncDspInitAVX2() to be called

...and make gif2webp and vwebp compile without them.
Makefile.vc still to be updated...
Meanwhile the CL environment variable can be supplemented with
set CL=/DWEBP_HAVE_GL /IC:\opt\freeglut\include
Change-Id: I37a60b8c32aafd125bffa98b6cc9f57c022ebbd0
add a check for a libGL function (glOrtho) in addition to glutMainLoop
when establishing the need for libGL at link time.

(cherry picked from commit 2ccf58d648)
This wasn't used often and benefits were likely minimal. Dropping it
outright is a bit simpler than adding a compatibility ifdef.
provides some compatibility with older versions of autoconf.
tested with autoconf 2.59/automake 1.7/aclocal 1.7

EXPERIMENTAL -> WEBP_EXPERIMENTAL_FEATURES
the former is not used in the source; this adds
WEBP_EXPERIMENTAL_FEATURES to config.h

When the config option '--enable-libwebpdecoder' is specified, the
lean decoder library 'libwebpdecoder' will be created in addition to
libwebp. Also dwebp binary will be linked to libwebpdecoder, if this
config option is specified.
