[PATCH v4 0/8] imap-send: Windows support

Here's the 4th iteration of my patches for Windows-compatibility in imap-send.

 - Patch 1-3 is about getting rid of or rewriting
   code with portability issues.
 - Patch 4 fixes a compilation error on Windows
 - Patch 5 enables compilation of imap-send
 - Patch 6-7 enables SSL-suport for mingw
 - Patch 8 enables imap-send and SSL for msvc

Changes in this iteration compared to the previous
are as follows:
 - Patch 3/8 calls "sh -c" instead of "/bin/sh -c"
 - Patch 5/8 keeps the list sorted

Thanks to Johannes Sixt for reviewing v4
