[5] Fixed an issue whereby cjpeg would segfault if a Windows bitmap with a
negative width or height was used as an input image (Windows bitmaps can have
a negative height if they are stored in top-down order, but such files are
rare and not supported by libjpeg-turbo.)

[5] Source buffers for the TurboJPEG C API functions, as well as the
jpeg_mem_src() function in the libjpeg API, are now declared as const pointers.
This facilitates passing read-only buffers to those functions and ensures the
caller that the source buffer will not be modified. This should not create any
backward API or ABI incompatibilities with prior libjpeg-turbo releases.

negative width or height was used as an input image (Windows bitmaps can have
a negative height if they are stored in top-down order, but such files are
rare and not supported by libjpeg-turbo.)
[2] Fixed an issue whereby, under certain circumstances, libjpeg-turbo would
incorrectly encode certain JPEG images when quality=100 and the fast integer
forward DCT were used. This was known to cause 'make test' to fail when the
library was built with '-march=haswell' on x86 systems.

[3] Fixed an issue whereby libjpeg-turbo would crash when built with the latest
& greatest development version of the Clang/LLVM compiler. This was caused by
an x86-64 ABI conformance issue in some of libjpeg-turbo's 64-bit SSE2 SIMD
routines. Those routines were incorrectly using a 64-bit mov instruction to

upsampling routine that caused a buffer overflow (and subsequent segfault) when
decompressing a 4:2:0 JPEG image whose scaled output width was less than 16
pixels. The "plain" upsampling routines are normally only used when
decompressing a non-YCbCr JPEG image, but they are also used when decompressing
a JPEG image whose scaled output height is 1.

security threat, but removing the warnings makes it easier to detect actual
security issues, should they arise in the future.
