Okay. I suggest we add
  const char *Curl_strerror (struct connectdata *conn, int err);
to curl_strerror.c and add a connectdata::syserr_buf[].
Hopefully that makes it thread-safe.

I've made one that handles errors from sys_errlist[] and
Winsock errors. Uses strerror_r() where available.

Attached diff and new file curl_strerror.h.

PS. Made a separate get_winsock_error() function since
the system default messages are so long and incomprehensible.
