travis-ci: build and test Git on Windows
Most Git developers work on Linux and they have no way to know if their changes would break the Git for Windows build. Let's fix that by adding a job to TravisCI that builds and tests Git on Windows. Unfortunately, TravisCI does not support Windows. Therefore, we did the following: * Johannes Schindelin set up a Visual Studio Team Services build sponsored by Microsoft and made it accessible via an Azure Function that speaks a super-simple API. We made TravisCI use this API to trigger a build, wait until its completion, and print the build and test results. * A Windows build and test run takes up to 3h and TravisCI has a timeout after 50min for Open Source projects. Since the TravisCI job does not use heavy CPU/memory/etc. resources, the friendly TravisCI folks extended the job timeout for git/git to 3h. Things, that would need to be done: * Someone with write access to would need to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI repository setting [1]. Afterwards the build should just work. Things, that might need to be done: * The Windows box can only process a single build at a time. A second Windows build would need to wait until the first finishes. This waiting time and the build time after the wait could exceed the 3h threshold. If this is a problem, then it is likely to happen every day as usually multiple branches are pushed at the same time (pu/next/ master/maint). I cannot test this as my TravisCI account has the 50min timeout. One solution could be to limit the number of concurrent TravisCI jobs [2].
