703e20235a cleanups: unnecessary casts, unified const_1, eliminate cross-.c file
prototypes (heresy!), add spaces in places like "flags&NETSTAT_CONNECTED",
removed unused #defines, #ifdef -> #if, use uint32_t for ipv4 addrs.

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

a389651115 Remove bb_strlen() in favor of -fno-builtin-strlen. Saves as many bytes
as the old optimization did (actually does slightly better under gcc 4.0), and
simplifies the code.
