wget: add support for https

Allow wget to support https URLs.  Changes are:

- Add mingw_popen2 which uses a named pipe to allow bidirectional
  communication with a child process;
- Modify ssl_client to accept a WIN32 handle instead of a file
  descriptor as an argument;
- Allow tls_get_random to open /dev/urandom;
- Using the above changes implement a WIN32 version of spawn_ssl_client
  in wget.

This closes GitHub issue #75.

Also, enable authentication in wget.
