* introduce non-loop-unrolled version of function and use them when the image size is not a multiple of 12 or 16
* Remove tests for imagesize being a multiple of 16 or 12 to handle functions with unrolled loops
* Use non-unrolled functions when image size is not a multiple of 12 or 16
* use std_blend when image is odd size
Memory allocations and image size requirements changed to be as needed for 64 byte alignment.
Self-test code for Blend modified accordingly and added Self-test for the delta functions.
2) Changed image class buffer related functions
3) Improved format selection for local cameras
4) Removed imagesize check for swscale
5) Fixed mmap unexpected memory size when changing capture options
6) Fixed unrelated bug in zmdc.pl: sockets directory doesn't exist
1) Delta and blend SSE and standard alogirthms inside
2) Changed event streaming to use sendfile() syscall if available
3) Direct memory capture (Less memcpys required)
4) Added macros for BGR24 and RGB32(and its variants) formats
5) Modified Monitors database table to add a target colorspace option
6) Changed most image buffer allocations to be on 16 byte boundary, work still in progress
7) Added Target colorspace instead of the old colours selection. this one also visible to local cameras
8) Replacing Y deltas option with ZM_CPU_EXTENSIONS
9) Added SSE detection code
10) Changed some code to make linking success with inlining enabled.
11) Some other changes and work still in progress for some listed above
