I fixed (worked arround) bug pqReadData function on HPUX

I used to get a "could not receive data from server: Error: 0" error message from the pqReadData function in fe-misc.c:491. Turns out recv() returnes -1 but set errno to 0. I just guessed that means theres nothing more to read and added a line

if (SOCK_ERRNO == 0) return someread;

which made the problem go away. I have not taken the time to investigate further and I am afraid my expertise is insufficient :)

Sorry about my poor Server-programming, hope this points you in the right direction.
