5cb54b5adc init: downgrade ENABLE_DEBUG_INIT to just a #define to prevent people
from selecting it in error. It has to be used ONLY for debugging
 init, never in production, as resulting init has serious differences.

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
