Replace most usages of ntoh[ls] and hton[sl] with pg_bswap.h.

Browse Source 
All postgres internal usages are replaced, it's just libpq example
usages that haven't been converted. External users of libpq can't
generally rely on including postgres internal headers.

Note that this includes replacing open-coded byte swapping of 64bit
integers (using two 32 bit swaps) with a single 64bit swap.

Where it looked applicable, I have removed netinet/in.h and
arpa/inet.h usage, which previously provided the relevant
functionality. It's perfectly possible that I missed other reasons for
including those, the buildfarm will tell.
