Windows support

[lucasz93]

• Windows support by using the old WinOFED source code (still available for download on the Open Fabrics web site).
• Linux still works.
• hdrdmacp now compiles into hdrdmacp.dll and hdrdmacp.exe - able to integrate the library into other programs.
• Didn't restructure the files into subdirectories because this will make it easier to merge with your SVN repo
• CMake support
• Also fixed Segmentation fault after successful transfer #3

This PR does not actually resolve issue#3 for me. Tested with the server running on Debian 12 and the client on Fedora 41, and vice-versa.

# ./hdrdmacp -m 1 -n 4 -s
