Fix an EINVAL on evbuffer_write_iovec on OpenSolaris. The writev() call is limited to at most IOV_MAX iovecs (or UIO_MAXIOV, depending on whom you ask). This isn't a problem anywhere we've tested except on OpenSolaris, where IOV_MAX was a mere 16. This patch makes us go from "use up to 128 iovecs when writing" to "use up to 128 iovecs when writing, or IOV_MAX/UIO_MAXIOV, whichever is less". This is still wrong if you somehow find a platform that defines IOV_MAX < UIO_MAXIOV, but I hereby claim that such a platform is too stupid to worry about for now. Found by Michael Herf.
