Replace our custom version of Android.mk with instructions on how to build a libjpeg-turbo SDK for Android using autotools. Upon consulting with AOSP, it appears that Android.mk isn't really necessary except when building libjpeg-turbo for use by the Android platform itself, and it makes more sense for them to maintain the makefile for that purpose rather than for it to be upstreamed. ndk-build has serious limitations that prevent it from being used to generate static libjpeg-turbo libraries (mainly, it isn't possible to combine pre-built objects from one module into a static library for another module, which is necessary because the SIMD extensions sometimes have to be built with different CFLAGS than the rest of the code.) In general, it's just better not to introduce a new build system.

This patch accomplishes the following:
...
-- Auto-generates HAVE_LOCALE_H macro and adds it to jconfig.h (this is used by rdjpgcom.c.)
-- Reconciles the description and ordering of macros between config.h.in and jconfig.h.in, so the two files can be easily diffed.
-- Eliminates the use of the autoheader-generated config.h in the project and moves relevant internal-only macros into a new file, jconfigint.h. This is to avoid "already defined" warnings in files that were including both config.h (to get the internal autotools package information or the INLINE definition) and jconfig.h.

Work around an issue in Visual C++ 2010 and 2013 that was causing the 256-bit bitmap test in the regression tests to fail. More specifically, when optimization is enabled in these versions of Visual C++, the optimizer seems to get confused by the following code block:
...
delta = cur0 * 2;
cur0 += delta; /* form error * 3 */
errorptr[0] = (FSERROR) (bpreverr0 + cur0);
cur0 += delta; /* form error * 5 */
bpreverr0 = belowerr0 + cur0;
cur0 += delta; /* form error * 7 */
Each time cur0 is incremented by delta, the compiled code doubles the value of delta (WTF?!) Thus, by the time the end of the block is reached, cur0 is equal to 15 times its former self, not 7 times its former self as it should be. At any rate, it was a lot simpler to just refactor the code so that it uses multiplication.
