[libvirt] compile option: --without-gnutls

Hi libvirt-list, Full disclosure: this is the first open source project I've tried to contribute to and I'm still learning the process and tools. In any case, Mikhail Gusarov started a thread on this a while back and I've tried to take it to conclusion. I needed to remove tls for 0.8.4 so I coded up a --without-gnutls configure option using Mikhail's partial code as a template. Then I pulled down 0.9.12 and came up with a patch that I'd like to push out to the commununity. I'm not adding any "new" functionality other than the configure option. The tls calls/structs are just #ifdef'd for the most part. In a couple of places I had to flip the logic for "if (!tls_struct) else", and also had to modify a few function calls to pass void * instead of tls pointers. I built --with-gnutls, --without-gnutls, and no option specified (defaults to --with-gnutls). make check is clean except for: TEST: libvirtdconftest .....!!!!!!...!!!!!!!!!!!!!!!!!!!!!!!!! 39 FAIL ...which consists mostly of this sasl failure: 39) Test corruption ... libvir: Config File error : unsupported configuration: remoteReadConfigFile: /home/ubu/git/libvirt/tests/../daemon/libvirtd.conf: auth_tcp: unsupported auth sasl FAILED ...so I'm trying to track that down, and also need to run syntax-check and valgrind tests. Once I get the tests passing what's my next step? Are you okay with this approach? Do you want a preview of my diffs? Do I need to write additional tests for this new option or update any documentation? Thanks, Chris Van Heuveln
