/**
* Parse raw MIME-data into a MIME-object.
*
* You may call this function several times on the same object; old data are cleared using
* dc_mimeparser_empty() before parsing is started.
*
* After dc_mimeparser_parse() is called successfully, all the functions to get information about the
* MIME-structure will work.
*
* @private @memberof dc_mimeparser_t
* @param mimeparser The MIME-parser object.
* @param body_not_terminated Plain text, no need to be null-terminated.
* @param body_bytes The number of bytes to read from body_not_terminated.
