Make EAttachment a little more thread-safe.

EAttachment is now used from worker threads by EMailFormatterAttachment,
so add some thread-safe accessor functions to eliminate potential races.

Added thread-safe functions:

    e_attachment_dup_disposition()
    e_attachment_ref_file()
    e_attachment_ref_file_info()
    e_attachment_ref_icon()
    e_attachment_ref_mime_part()
    e_attachment_dup_description()
    e_attachment_dup_thumbnail_path()

Renamed functions:

    e_attachment_get_mime_type() -> e_attachment_dup_mime_type()

Removed non-thread-safe functions:

    e_attachment_get_file()
    e_attachment_get_file_info()
    e_attachment_get_icon()
    e_attachment_get_mime_part()
    e_attachment_get_description()
    e_attachment_get_thumbnail_path()
