Missing C API

[mbanth]

The sdram.h file includes function signatures that use clocks, ports (including buffered ports), references (including a reference to a movable pointer), and streaming channel ends (including a streaming channel end array).

The memory_address_allocator.h file includes function signatures that use XC interfaces (including a server interface) and references. One function signature includes the [[sametile]] attribute and another one includes the [[distributable]] attribute.

Not surprisingly, the implementation of each of the API functions use the same signatures, hence the same non-C features.

A C API has not been provided.
