With the addition of the IPv6 dummy header the logic to set the
correct ethernet protocol has become scattered across the code
and also poured into the actual packet writing code.
Once command line parsing is completed a consistent set of frame
generating parameters should be established.
This change consolidates the ethernet header protocol
determination to one point, with the added benefit of resolving
a possible duplicate IPv4 / IPv6 paramter setting in the same
manner as is done for other conflicting parameters.

Add wtap_compressed_file_extension(), which returns NULL for
WTAP_UNCOMPRESSED and the appropriate file extension for other
compression types.
Add wtap_compression_type_supported(), which returns TRUE for
WTAP_UNCOMPRESSED and all supported compression types and FALSE
otherwise. ("Supported" means "the code can decompmress files in that
compression format and can write files in that compression format", so
WTAP_GAIP_COMPRESSED is supported iff libwiretap is built with zlib.)
In MainWindow::fileAddExtension, instead of checking for
WTAP_GZIP_COMPRESSED and using ".gz" as the extension, use the extension
returned by wtap_compressed_file_extension() for the compression type.

2) leaves space in the interfaces in question for additional compression

(No, this is not part 1 of an implementation of additional compression
types, it's just an API cleanup. Implementing additional compression
types involves significant work in libwiretap, as well as UI changes to
replace "compress the file" checkboxes with something to indicate *how*

It means "snapshot length unknown".
For most file formats, the snapshot length isn't recorded (even for
formats that support slicing - all they record is the on-the-network
length, and length after slicing, for each packet), so it's ignored in
the dumper.
The one exception is pcap, which records it in the file header; if it's
unknown, the pcap-writing code picks the maximum supported snapshot
length for the file's link-layer header type.
