Since this changes the file download mechanism, I think this could use
some wider testing before being deployed. Please test.

Changes compared to 2.877:
- "Direct Connection" now uses the WinINet API to fetch URLs.
This enables HTTPS and FTPS protocol support, and caching of mirrors.lst
and setup.ini.
The existing, hand-built URL fetching, which only supports HTTP and FTP,
is still available by choosing "Direct (legacy)".
- Fixes to "Use Internet Explorer Proxy Settings" mode
Progress is now reported for downloads.
Unwanted caching in "Temporary Internet Files" of package archives has
been fixed.
(Addresses: https://cygwin.com/ml/cygwin/2016-09/msg00403.html)
A bug causing a long delay before downloading setup.ini from package
repositories without a compressed setup.ini has been fixed.
- Add --allow-unsupported-windows option
Don't check the windows version.
The Cygwin mirror list is not read, so a URL (e.g. a Cygwin time machine
circa) should be given with --site or via the GUI.
- Remove support for some long-obsolete setup.ini syntax (omitted
version:, omitted size and checksum, various undocumented tokens)
- Remove cruft
