or first bytes from the next DHCP packet option.

 is misleading!

084266ed52 fix several problems with config parser: 
a bug where it underflows the string
 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

 it wasn't working at all.
 stop using global data for flags in main(), opt
 bitfield works as well.
