* zebra.h: BSD BYTE_ORDER define isn't available everywhere,
define if needs be.
* checksum.h: new file. checksum.c exports in_cksum, provide
a header for it.
* checksum.c: (in_cksum) callers shouldn't have to know it uses
a u_short internally, change to void *.
* Makefile.am: Add checksum.h
* command.h: remove bogus trailling slash.
* md5.c: (general) Update it for the twentieth century. ANSI
declarations are widely supported now.. Don't include system
headers, only include zebra.h. Use POSIX types (the
alternative is to define u_int64_t in a portable way - rest
of Quagga needs same cleanup).
Make endian-conditional code be compiler conditional rather
than preprocessor conditional, so that breakage gets noticed
quicker.
* md5.h: POSIX types. Get rid of the odd __P() non-ANSI capable
compiler compatibility hack.
