Routine Description:

  Generate an encapsulating section of type EFI_SECTION_COMPRESSION
  Input file must be already sectioned. The function won't validate
  the input files' contents. Caller should hand in files already
  with section header.

Arguments:

  InputFileName  - Name of the input file.

  InputFileAlign - Alignment required by the input file data.

  InputFileNum   - Number of input files. Should be at least 1.

  SectCompSubType - Specify the compression algorithm requested.

  OutFileBuffer   - Buffer pointer to Output file contents

Returns:

  EFI_SUCCESS           on successful return
  EFI_INVALID_PARAMETER if InputFileNum is less than 1
  EFI_ABORTED           if unable to open input file.
  EFI_OUT_OF_RESOURCES  No resource to complete the operation.
