Start a connection to every suitable directory authority, using connection purpose dir_purpose and uploading payload (of length payload_len). The dir_purpose should be one of 'DIR_PURPOSE_UPLOAD_{DIR|VOTE|SIGNATURES}'.
router_purpose describes the type of descriptor we're publishing, if we're publishing a descriptor – e.g. general or bridge.
type specifies what sort of dir authorities (V3, BRIDGE, etc) we should upload to.
If extrainfo_len is nonzero, the first payload_len bytes of payload hold a router descriptor, and the next extrainfo_len bytes of payload hold an extra-info document. Upload the descriptor to all authorities, and the extra-info document to all authorities that support it.
