Message:

more consistent naming scheme:

async_data_blob_receive → async_data_receive
async_data_string_receive → async_string_receive
CLIPBOARD_TAG_BLOB → CLIPBOARD_TAG_DATA

async_data_receive can now check the granularity of the received data
async_string_receive can now return the raw size of the received data

replace several common patterns of async_data_write_receive/_finalize
with a single async_data_receive/_string_receive (this greatly improves
code readability)
