Guy Harris 846bb53948 Add a Buffer to wtap_pkthdr to hold file-type-specific packet metadata.
For example, this can be used for pcap-ng options not mapped to
file-type-independent metadata values.

Guy Harris 1b6cc6320e Add support for plugins to handle pcap-ng block types.
We rename "file format" plugins to "libwiretap" plugins, as they can
register as read handlers for a new file type, read/write handlers for a
pcap-ng block type (or both).

To register as a pcap-ng block type handler, in the
register_wtap_module() routine of your plugin, call
register_pcapng_block_type_handler() with the pcap-ng block type and
pointers to your routines to read and write those blocks.  Those
routines should read and write REC_TYPE_FILE_TYPE_SPECIFIC records, with
the block type in the pseudo-header for the record in the struct
wtap_pkthdr structure, with time stamps stored in that structure, and
with a blob of data for the rest of the record.

This is for bug 8590.
