LGTM
Make sure WIN_BUILD_OUTPUT is set when copying Windows build output

Without this check, the xctools step tries to rsync everything from the
root directory into the build tree.
Make sure REPO_PROD_CACERT and REPO_DEV_CACERT are set

Without these checks, resolve_path incorrectly resolves these empty
variables as references to the top-level directory in the build tree.
These pass the check in check_repo_signing_file because the directory
exists, then the xenclient-repo-certs recipe uses them in its SRC_URI
and tries to copy the whole build tree under its working directory.

Also move all the checks for these variables earlier in do_oe_setup,
before it tests whether xenclient/conf/local.conf exists. Otherwise, if
the setupoe step fails on one of these checks, rerunning it won't
generate a usable xenclient/conf/local.conf file.

Fix error checking for WIN_BUILD_OUTPUT and REPO_*_CACERT

Make Windows Build Machine from public URLs (step 1)

This change is the first result of the effort to install
all tools needed to build OpenXT windows components using
public URLs.

- Update Helper URL
- Remove libre branch tag
- Update Cygwin URL
- Update nsis URL (2.46 now) and Check we are using >= than 2.23
- Update capicom URL
- Add MSMSrc patch
- update dotNetFx45_Full_setup.exe URL
- Update SQLSCE32 and SQLSCE64 URLs
- Update VS2012U4 URL
- Update Wix URL

Wix URL is now hardcoded in install-wix.ps1 (This is needed because
if we put this URL in the config file the XML parser fails because
of the &, so embedding the URL here is a workaround for the problem)

[do_build.sh] Remove optional steps...

... to minimize build breakage.
- nilfvm does nothing.
- copy requires extra configuration lines that are not yet documented, or it tries to copy stuff to /master, which breaks the build for most users.
- extra_pkgs can be replaced by just manually building the extra packages needed, which widely vary between users anyway.
- packages_tree also requires extra configuration. That step is probably not needed for most users either.
