New point version.

2.1.2

Significant changes relative to 2.1.1

1. Fixed a regression introduced by 2.1 beta1 that caused the remaining GAS implementations of AArch64 (Arm 64-bit) Neon SIMD functions (which are used by default with GCC for performance reasons) to be placed in the .rodata section rather than in the .text section. This caused the GNU linker to automatically place the .rodata section in an executable segment, which prevented libjpeg-turbo from working properly with other linkers and also represented a potential security risk.

2. Fixed an issue whereby the tjTransform() function incorrectly computed the MCU block size for 4:4:4 JPEG images with non-unary sampling factors and thus unduly rejected some cropping regions, even though those regions aligned with 8x8 MCU block boundaries.

3. Fixed a regression introduced by 2.1 beta1 that caused the build system to enable the Arm Neon SIMD extensions when targetting Armv6 and other legacy architectures that do not support Neon instructions.

4. libjpeg-turbo now performs run-time detection of AltiVec instructions on FreeBSD/PowerPC systems if AltiVec instructions are not enabled at compile time. This allows both AltiVec-equipped and non-AltiVec-equipped CPUs to be supported using the same build of libjpeg-turbo.

5. cjpeg now accepts a -strict argument similar to that of djpeg and jpegtran, which causes the compressor to abort if an LZW-compressed GIF input image contains incomplete or corrupt image data.
