  DXE capsule library.\r
\r
  Caution: This module requires additional review when modified.\r
  This module will have external input - capsule image.\r
  This external input must be validated carefully to avoid security issue like\r
  buffer overflow, integer overflow.\r
\r
  SupportCapsuleImage(), ProcessCapsuleImage(), IsValidCapsuleHeader(),\r
  ValidateFmpCapsule(), and DisplayCapsuleImage() receives untrusted input and\r
  performs basic validation.\r
