    sys/geom             geom_gpt.c 
  Complete rewrite in preparation of adding support for control
  requests. The following features have been added:
  1. Extensive checking and validation of both the primary and
     secondary headers to protect against corrupted data and to
     take advantage of the redundancy to allow the GPT to be
     used in the face of recoverable corruption.
  2. Dynamic data-structures to avoid hardcoding gratuitous
     table limits so as to support the creation of GPT tables
     of (as of yet) unspecified size.
  3. Only allow kernel dumps to swap partitions to provide the
     necessary anti-footshooting measures. Linux swap partitions
     are allowed.
  4. Complete dump of the GPT configuration, including labels.
  5. Supports Byte Order Mark (U+FEFF) handling for big-endian,
     little-endian and mixed-endian partition names.
