0e9bf6442b Fix a segfault that would occur in decompress-only mode if -alloc was specified without -tile.

d4b453c26e Back-port the -subsamp option from 1.4 rather than use the hackish approach of replacing 4:2:2 with 4:4:0. This has the added advantage of allowing the user to test only a specific level of subsampling.

c6501f7f5f Add the ability to test scaling when decompressing to YUV; compression from YUV to JPEG; and YUV padding. Replace clunky -411 and -440 parameters with a -subsamp parameter that allows any of the subsampling options to be tested in isolation.

07e982d9b4 Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes.

c45653e471 Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1.
