Version 0.6.4 : Minor changes and bug fixes

Changes since v0.6.3:

Features

#528 Can now register memory areas with the CUDA driver as read-only (in addition to other parameters)
#519 Quick & somewhat-dirty support for the use of "external memory resources" (mostly Direct3D or NVSCI buffers and semaphores; but not including semaphores etc. for now)

#535 copy_parameters_t::set_endpoint_untyped() now properly calling an inner set_endpoint_untyped()
#527 copy_parameters_t::set_single_context no longer mistakenly taking an endpoint_t parameter
#528 When mapping a region pair, not insisting on the same address on both the host and the device (which had made it impossible for this to succeed with older GPUs).
#521 Avoid a compiler compiler warning when overriding the context for the current scope
#520 Removed unnecessary uses of a context-wrapper scoped-context-override
#517 cuda::memory::typed_set() no longer mistakenly accepts values of size 8 (which have no special CUDA API call).
#516 Corrected types and casting in stream_t::enqueue_t::write_single_value()
#515 Resolved a case of missing includes when including only certain headers
#514 Now providing a definition of cuda::memory::managed::allocate(device, num_bytes) (which was declared but not defined)

#522 Renamed synch to sync in multiple identifiers
#529 program_t::add_registered_globals() can now take any container of any string-like type.
#523 Now passing device_t's by const-ref in more cases, avoiding copying and enabling re-use of a reference to the primary context.
#521 Reduce boilerplate + avoid warning when overriding context for the current scope resolved-on-development task

#504 Fixed build failure with cooperative_groups on GitHub Actions Windows runners and CUDA >= 11.7
