[PATCH v3 0/2] MR3269: wininet: Handle http headers correctly when length is 0

[Hans Lehnert (＠hanslehnert)]

In HttpSendRequestW and HttpSendRequestExW, if the header pointer is not
null but the length parameter is 0, the header length should be derived
from the string length instead.

In HttpSendRequestA and HttpSendRequestExA, on the same scenario, the
function should fail instead.
