5de454b291 libjpeg-turbo has never supported non-ANSI compilers, so get rid of the crufty SIZEOF() macro. It was not being used consistently anyhow, so it would not have been possible to build prior releases of libjpeg-turbo using the broken compilers for which that macro was designed.

bc56b754e1 Get rid of the HAVE_PROTOTYPES configuration option, as well as the related JMETHOD and JPP macros. libjpeg-turbo has never supported compilers that don't handle prototypes. Doing so requires ansi2knr, which isn't even supported in the IJG code anymore.

e5eaf37440 Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons. They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)

a6ef282a49 Some of the IJG headers say "Modified by", so clarify that our "Modifications" are not referring to these.

a49c4e5247 The SIMD quantization algorithm does not produce correct results with the fast forward integer DCT and JPEG qualities >= 98, so for now, use the non-SIMD quantization function under those circumstances.

35c4719638 Make sure the work space memory is properly aligned 
We use the heap allocators to avoid having more than one implementation
of the alignment logic.

dedc42e268 "Optimise" quantization step by replacing the division by a multiplication. 
This has no measurable difference right now but makes it possible to do
SIMD implementations of this stage.

49dcbfbf13 Split up the forward DCT routine into three stages 
Divide it into sample conversion, DCT and quantization in order to
easily provide alternative implementations of each stage.
