Do not allocate memory on host in buffer_impl constructors when user's ptr is provided. This is possible because the ownership of that memory is given to the constructed SYCL buffer for the duration of it' lifetime. The memory still need to be allocated in constructor that takes iterators as they can point to non-consecutive memory(need consecutive memory to interact with OpenCL). This may improve performance as we avoid several memory allocation/copy. As required by the Specification the host memory now always allocated using allocator provided by user. Moved methods that allocate, fill and copy memory to separate class. Copy method was improved to support device to host and host to device partial(aka CopyRect) version of copies. So, now the buffer_impl class is decoupled from OpenCL. Fix possible bug, now constructor from shared_ptr stores a copy of shared_ptr in lambda to avoid deallocation of memory until buffer is destructed or set_final_data is invoked to override destination for updating host memory(aka copy back).

Modified handler class so it creates special CG class. CG class represents different types of command groups, such as kernel execution, fill and so on. This is needed to decouple Scheduler from template parameters introduced by lambda, various ranges and arguments.

This patch introduces new scheduler which is enabled when SCHEDULER_20 macro is set(set by default). The new scheduler is based on accessor rather on buffer, so it will support images. Also now there are two commands that implements moving memory to other contexts instead of one - alloca memory and memcpy. There is new command - release memory which will be ran during the sycl::buffer or sycl::image object destruction and releases memory instances for the memory object.

This patch fixes compilation of sycl application with default compiler(without specifying -fsycl). To do this default KernelInfo implementation is added + check that skips integration header processing if specialization for KernelInfo(which is supposed to come from integraion header) is not available.
