wordlist.c: avoid compiler warnings for debug builds
Added code to create FULL passwd compatible strings in -list=format-tests.
These formats now generate these types (GPU formats not tested):
dynamic  (15,35,36,37,1015,1401), MSCHAPv2 mschapv2-naive, nethalflm, netlm,
netlmv2, netntlm, netntlm-naive, netntlmv2.  They probabaly should be retestd
Initialize the Unicode system before calling listconf_parse_late()
and speed up --list=format-tests for GPU formats.
listconf.c: Handle the case where field 0 is given but no others. Example:
{WOWSIG"6D00CD214C8473C7F4E9DC77AE8FC6B3944298C48C7454E6BB8296952DCFE78D$73616C74", "PASSWORD", {"SOLAR"}}
