/* Print fi_info and related structs, enums, OR_able flags, addresses.
 *
 * Each printable type should be well formatted YAML.
 *
 * A struct is a dictionary containing one key named after the struct tag
 * which contains a dictionary of member-value mappings. The struct member
 * keys are the field names (not the types).
 *
 * Enum values are currently just bare strings.
 * OR-able flags are a list of the values, ie: [ VAL1, VAL2 ]
 *
 * YAML does not contain tabs.
 * Indentation delineates lists and dictionaries (or they can be inline).
 *
 * Printing functions are generally named after this pattern:
 *
 * struct fi_info : ofi_tostr_info(..., struct fi_info, ...)
 * fi_info->caps  : ofi_tostr_caps(..., typeof(caps), ...)
