[SVN] r9312

[Luke Daley]

• Added getters for buffer members and replaced direct member access with getter usage in callers.
• Added get_buffer_byte_at() which allows char by char access to a buffers data after performing range checking on the requested index.
• Added write_buffer_to_fd() which completely writes the contents of a buffer to a passed in file descriptor.
