15c0876191 Fix additional uninitialized values reported by valgrind

c90144950f When tjDecodeYUV() is used with a "fresh" decompressor instance (one that hasn't been previously used to decompress a JPEG image), then it needs comps_in_scan, data_precision, and the quantization tables to be defined. This patch also extends TJUnitTest to check for this error.

2bdc0425df Go ahead and call jinit_master_decompress() rather than trying to reproduce its functionality. That function does a few things that we were missing, including allocating the range limit table used by the plain C color conversion code.

693f4a5600 Fix an issue that prevented tjEncodeYUV2() and TJCompressor.encodeYUV() from working properly if the source image was very tiny. Basically, jpeg_start_compress() was attempting to write the JPEG headers, which was overrunning the YUV buffer. This patch removes the call to jpeg_start_compress() in tjEncodeYUV2() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.)

afc06929e0 Emulate colorspace extensions if they are not present in the libjpeg API. This allows the TurboJPEG wrapper to be used with libjpeg rather than libjpeg-turbo.
