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

4ea83bf562 uclibc insists on having 70k static buffer for crypt.
For bbox it's not acceptable. Roll our own des and md5 crypt
implementation. Against older uclibc:

   text    data     bss     dec     hex filename
 759945     604    6684  767233   bb501 busybox_old
 759766     604    6684  767054   bb44e busybox_unstripped

so, we still save on code size.
