ERF: Add support for new extension header and Provenance tags
Add support for Entropy Extension header, currently with one field. Uses
a conversion function to convert representation to bits.
Add various entropy and tap mode Provenance (ERF_TYPE_META) tags.
The only complex tag is ext_hdrs_added/removed. This tag consist of up
to 4 big endian uint32 bitfields, with each bit representing an
extension header number. ehdr_type_vals and a new ehdr_type_vals_short
are used to generate the tags. Custom printing is used for the header
line to display unknown values as integer and support the special case
of <All>: all supplied bits 1 meaning all extension headers removed.
Storage for the up to 4 subtree header_field id entries is in the first
4 extra hf_values[] for now, the ett value is reused.
Increase erfmeta_tag_info_ext_t ERF_HF_VALUES_PER_TAG to 32. A better
solution is needed sooner rather than later but the structure is only
allocated for tags that need it.
