Greg Morse reported a problem with POSTing using ANYAUTH to a server requiring

NTLM, and he provided test code and a test server and we worked out a bug
fix. We failed to count sent body data at times, which then caused internal
confusions when libcurl tried to send the rest of the data in order to
maintain the same connection alive.

(and then I did some minor reformatting of code in lib/http.c)

 - Peter O'Gorman pointed out (and fixed) that the non-blocking check in
   configure made libcurl use blocking sockets on AIX 4 and 5, while that
