This converts several of the selftests to return a status in their exit code about whether they 'worked'. A small bash script framework is added, with a selftest.sh in the mininmal example dirs that support it, and a ./minimal-examples/selftests.sh script that can be run from the build dir with no args that discovers and runs all the selftest.sh scripts underneath. That is also integrated into travis and the enabled tests must pass now for travis to pass. Travis does not have a modern libuv so it can't run a couple of tests which are nulled out if it sees it's running in travis env. |

lws minimal http client POST
This example demonstrates a multipart POST to
https://libwebsockets.org/testserver/formtest
setting both a form variable and uploading a short file.
The result of the POST form processing is captured and displayed in a hexdump.
This is programmatically POSTing to the same form you can access at
https://libwebsockets.org/testserver
in the "POST" tab with file upload.
By default the client action occurs using http/2 if
your lws was built with -DLWS_WITH_HTTP2=1.
