fix(BodyHandler): belle_sip_multipart_body_handler_new_from_buffer use now a const void* parameter instead of void* (buffer is not modified after all)

The are going to be used to implement a kind of floating ref for liblinphone C objects.

Separate body handlers begin transfer callbacks for receiving and sending files (the file body handler needs to open the file in different modes in these 2 cases).

Added possibility to add a user body handler inside a file body handler to dynamically edit the content of the file in both directions

Fix issue in multipart body splitting ('--' characters at the beginning of the boundary was kept in the part body).

Add belle_sip_body_handler_remove_header_from_ptr() and belle_sip_memory_handler_set_buffer() functions.
