This starts off an asynchronous read. Upto bytes_to_read will be read and stored in the message_block. The read will start at offset from the beginning of the file.
Implemented in ACE_POSIX_Asynch_Read_File.

Same as above but with scatter support, through chaining of composite message blocks using the continuation field.
