c-hyper: fix unused variable ‘wrote’

libcurl-security.3: be careful of setuid

Reported-by: Harry Sintonen

c-hyper: don't write to set.writeheader if null

Previously if a caller set CURLOPT_WRITEFUNCTION but did not set a
CURLOPT_HEADERDATA buffer, Hyper would still attempt to write headers to
the data->set.writeheader header buffer, even though it is null. This
led to NPE segfaults attempting to use libcurl+Hyper with Git, for
example.

Instead, process the client write for the status line using the same
logic we use to process the client write for the later HTTP headers,
which contains the appropriate guard logic. As a side benefit,
data->set.writeheader is now only read in one file instead of two.

m4: add security frameworks on Mac when compiling rustls

Previously compiling rustls on Mac would only complete if you also
compiled the SecureTransport TLS backend, which curl would prefer to
the Rust backend.

Appending these flags to LDFLAGS makes it possible to compile the
Rustls backend on Mac without the SecureTransport backend, which means
this patch will make it possible for Mac users to use the Rustls
backend for TLS.
