extended ocl::convertTo
Dropped the HAVE_DC1394_095 configuration macro.

We never set it, and libdc1394 0.9.5 is obsolete anyway - 1.0 came out
in 2004.

Note that 1.0 doesn't have the do_extra_buffering parameter.
remove CV_EXPORT from templates
fixed ocl::pyrUp for 2-byte types
removed useless output
removed needless divUp
added performance tests for data transfer operations
