zip_file_extra_fields_count() function counts the
  extra fields for the file at position index in the zip
  archive.
The following flags are supported:
ZIP_FL_CENTRALZIP_FL_LOCALZIP_FL_UNCHANGEDThe zip_file_extra_fields_count_by_id()
    function counts the extra fields with ID (two-byte signature)
    extra_field_id. The other arguments are the same as
    for zip_file_extra_fields_count().
Extra fields that are the same in the central directory and the
    local file header are merged into one. Therefore, the counts with
    ZIP_FL_CENTRAL and
    ZIP_FL_LOCAL do not need to add up to the same value
    as when given ZIP_FL_CENTRAL|ZIP_FL_LOCAL at the
    same time.
zip_file_extra_fields_count() and
  zip_file_extra_fields_count_by_id() fail if:
ZIP_ER_NOENT]zip_file_extra_fields_count() and
  zip_file_extra_fields_count_by_id() were added in
  libzip 0.11.
