No, but the only possible vales are 0, 1, 2 and 3

0 Being that an mmap()ed CamelMessageInfo is used, 1 that a
CamelMimeMessage is used and 2 that a non-mmap()ed CamelMessageInfo is
used. 3 That the TnyHeader instance is dead and should have been cleared
or that it's not yet initialized.

In case of 1 and 2, the camel_message_info_* API must be used, in case
of 2 the camel_mime_part and camel_mime_message API must be used.
