[util] Add utility to generate list of supported network cards

niclist.pl recursively scans specified source folders and builds a
list of supported NICs by looking for ISA_ROM and PCI_ROM lines and
outputs the list in text, CSV, JSON, HTML or DokuWiki format.  Sorting
and column selection is possible.

The pci-utils pci.ids file is fetched from SourceForge once a day to
also output the "official" vendor/device names associated with the PCI
device.
