73121c3c8c dhcpd,dumpleases: write and use 64-bit current time in lease file.
without it, determination of remaining lease time is unreliable.
 Yes, it's costly in code size, but without it, dumpleases output
 is misleading!

 a bug where it never frees parser_t struct
make read_config() return 0 if parser is NULL,
 make config_close() accept and ignore NULL parser -
 eliminates many if() blocks
reverse the sense of parser bit flags - negative flags
 are harder to grok.
hexdump: revert the change to use config parser, it is BIGGER
 and also requires additional quirks in parser
*: explicitly use PARSER_NORMAL instead of 0

21765fa063 udhcpc: kill undocumented -W, it was a no-op.
fix option parsing in the case some CONFIG_x are off.
 disable -b on NOMMU, make backgrounding work correctly
 (if a bit differently from MMU case). Previously,
 it wasn't working at all.
 stop using global data for flags in main(), opt
 bitfield works as well.

95891fc016 openvt: fix gross mismatch between us and "standard" openvt.
standard one even has different syntax!
  std: "openvt -c 12", we: "openvt 12"
  std: "openvt top", we: complain that "top" is not a number.
openvt: implement -c -w -s (-l -f -v are also accepted but ingnored)
