Support Clang/Xcode and support Kerberos on macOS

[amosavian]

This pull request adds module.modulemap to allow clang to treat this library as
a framework, allowing use of "import" rather than include and provides better
support for Swift binding.

Also krb5wrapper has been modified to support macOS.
I've disabled a section of code as gss_set_neg_mechs() is not defined on macOS.

Please note I've changed two cases of angled-bracket include to double-quoted one
as it did not compile on my computer. I hope it won't break anything on other systems.

It works pretty well now, i think @sahlberg would merge this one.

It needs some more changes.
The include files that are installed into /usr/include/smb2 should not change to use #include "" to include the other files that also end up in /usr/include/smb2. They should continue to use #include <>

i´ve added #include <> it should work on mac os normally.

When I use Swift Package Manager, so no headers would be found on /usr/include/smb2 and I don't know how to resolve this issue. @sahlberg
