[Dovecot] dovecot 1.0-test52 compile notes

Compile issues on an older BSD/OS 4.2 system:

src/lib/byteorder.h needs #include to pick up in_addr struct

src/lib/byteorder.c no "libgen" here (no basename()). Added it inline, no big deal, but you might want to have configure test for this and provide one if it's missing.

Also, on this system there are no types like "uint8_t" and "uint64_t" -- instead there are the u_int8_t and u_int64_t et al types. I added some global typedefs, but I gather this is a somewhat common issue, so you might want to test for these.
