Fix negative shift with IFAST FDCT and qual=100
With certain images, compressing using quality=100 and the fast integer
forward DCT will cause the divisor passed to compute_reciprocal() to be
1. In those cases, the library already disables the SIMD quantization
algorithm to avoid 16-bit overflow. However, compute_reciprocal()
doesn't properly handle the divisor==1 case, so we need to use special
values in that case so that the C quantization algorithm will behave
like an identity function.

Fix build error when compiling MIPS SIMD w/ -mfpxx
When compiled with -mfpxx (which is now the default on Debian), there are
some restrictions on the use of odd-numbered FP registers. More details
about FPXX can be found here:
https://dmz-portal.mips.com/wiki/MIPS_O32_ABI_-_FR0_and_FR1_Interlinking
This commit simply changes all uses of FP registers to an even-numbered
equivalent like this:
f0 -> f0
f1 -> f2
f2 -> f4
...
f8 -> f16
This commit should have no observable effect except that the MIPS assembly
will now compile with -mfpxx.
Closes #11

Fix cjpeg segfault when Windows BMP width/height<0
rdbmp.c used the ambiguous INT32 datatype, which is sometimes typedef'ed
to long. Windows bitmap headers use 32-bit signed integers for the
width and height, because height can sometimes be negative (this
indicates a top-down bitmap.) If biWidth or biHeight was negative and
INT32 was a 64-bit long, then biWidth and biHeight were read as a
positive integer > INT32_MAX, which failed the test in line 385:
if (biWidth <= 0 || biHeight <= 0)
ERREXIT(cinfo, JERR_BMP_EMPTY);
This commit refactors rdbmp.c so that it uses the datatypes specified by
Microsoft for the Windows BMP header.
This closes #9 and also provides a better solution for mozilla/mozjpeg#153.

Further improvements to partial image decoding
When using context-based upsampling, use a dummy color conversion
routine instead of a dummy row buffer. This improves performance
(since the actual color conversion routine no longer has to be called),
and it also fixes valgrind errors when decompressing to RGB565.
Valgrind previously complained, because using the RGB565 color
converter with the dummy row buffer was causing a table lookup with
undefined indices.

Further exception cleanup
Use a new checked exception type (TJException) when passing through
errors from the underlying C library. This gives the application a
choice of catching all exceptions or just those from TurboJPEG.
Throw IllegalArgumentException at the JNI level when arguments to the
JNI function are incorrect, and when one of the TurboJPEG "utility"
functions returns an error (because, per the C API specification, those
functions will only return an error if one of their arguments is out of
range.)
Remove "throws Exception" from the signature of any methods that no
longer pass through an error from the TurboJPEG C library.

Throw idiomatic unchecked exceptions from the Java classes and JNI wrapper if there is an unrecoverable error caused by incorrect API usage (such as illegal arguments, etc.), and throw Errors if there is an unrecoverable error at the C level (such as a failed malloc() call.)
Change the behavior of the bailif0() macro in the JNI wrapper so that it doesn't throw an exception for an unexpected NULL condition. In fact, in all cases, the underlying JNI API function (such as GetFieldID(), etc.) will throw an Error on its own whenever it returns NULL, so our custom exceptions were never being thrown in that case anyhow. All we need to do is just detect the error and bail out of the C code.
This also corrects a couple of formatting issues (semicolons aren't needed at the end of class definitions, and @Override should be specified for the methods we're overriding from super-classes, so the compiler can sanity-check that we're actually overriding a method and not declaring a new one.)

Now that the TurboJPEG API is reporting libjpeg warnings as errors, an "Invalid SOS parameters for sequential JPEG" warning surfaced in tjDecodeYUV*(). This was caused by the Se member of jpeg_decompress_struct being set to 0 (it is normally set to a non-zero value when the start-of-scan markers are read, but there are no SOS markers in this case, because we're not actually decompressing a JPEG file.)

Fix a segfault that occured in the MIPS DSPr2 fancy upsampling routine when downsampled_width==3. Because the DSPr2 code unrolls the loop for the middle columns (refer to jdsample.c), it has the effect of performing two column iterations, and that only works properly if the number of columns (minus the first and last) is >= 2. For the specific case of downsampled_width==3, this patch skips to the second iteration of the unrolled column loop.

If a warning (such as "Premature end of JPEG file") is triggered in the underlying libjpeg API, make sure that the TurboJPEG API function returns -1. Unlike errors, however, libjpeg warnings do not make the TurboJPEG functions abort.

Back out r1555 and r1548. Using setenv() didn't fix the iOS simulator issue. It just replaced an undefined _putenv$UNIX2003 symbol with an undefined _setenv$UNIX2003 symbol. The correct solution seems to be to use -D_NONSTD_SOURCE when generating our official builds.

Fix the Windows build. I remember now why I used putenv() originally-- because Windows doesn't have setenv(). We could use _putenv_s(), but older versions of MinGW don't have that either. Fortunately, since all of the environment values we're setting in turbojpeg.c are static, we can just map setenv() to putenv() using a macro. NOTE: we still have to use _putenv_s() in turbojpeg-jni.c, but at least people who may need to build with an older version of MinGW can still do so by disabling the Java build.

__WORDSIZE doesn't seem to be available on platforms other than Mac or Linux, and best practices are for user-level code not to rely on it anyhow, since it's meant to be an internal macro. Fortunately, autoconf already has a way of determining the word size at configure time, so it can be passed into the compiler. This should work on any platform and has been tested on all of the Un*x platforms we support (Linux, Mac, FreeBSD, Solaris.)

Unless you define _ANSI_SOURCE, then putenv() on Mac is renamed to putenv$UNIX2003(), and this causes problems when trying to link an i386 iOS application (for the simulator) against the TurboJPEG static library. It's easiest to just use setenv() instead.

Fix a bug in the 64-bit Huffman encoder that Google discovered when encoding some very specific (and proprietary) aerial images using quality=98, an optimized Huffman table, and the ISLOW DCT. These images were causing the Huffman bit buffer to overflow, because the code for encoding the DC coefficient was using the equivalent of the 32-bit version of EMIT_BITS(). Thus, when 64-bit code was used, the DC coefficient code was not properly checking how many bits were in the buffer before attempting to add more bits to it. This issue appears to have existed in all versions of libjpeg-turbo.

Oops. OS X doesn't define __WORDSIZE unless you include stdint.h, so apparently the Huffman codec hasn't ever been fully accelerated on 64-bit OS X.

If libjpeg-turbo is configured with a non-default prefix, such as /usr, then use the docdir variable defined by autoconf 2.60 and later, if available. This will, for instance, install the documentation under /usr/share/doc/libjpeg-turbo by default if prefix=/usr, unless docdir is overridden. When using earlier versions of autoconf, docdir is set to ${datadir}/doc, as it always has been.

Enable silent build rules for the NASM objects, if the source is configured with automake 1.11 or later. NOTE: the build still spits out "error: ignoring unknown tag NASM" for each object, but unfortunately, if we remove "--tag NASM" from the command line, the build breaks under older versions of automake (it aborts with "unable to infer tagged configuration.")
