recipetool: create: support node.js code outside of npm
If you have your own node.js application you may not publish it (or at least not immediately) in an npm registry - it might just be in a repository on github or on your local machine. Add support to recipetool create for creating recipes to build such applications - extract their dependencies, fetch them, and add corresponding npm:// URLs to SRC_URI, and ensure that LICENSE / LIC_FILES_CHKSUM are updated to match. For example, you can now run: recipetool create https://github.com/diversario/node-ssdp (I had to borrow some code from bitbake/lib/bb/fetch2/npm.py to implement this functionality; this should be refactored out but now isn't the time to do that refactoring.) Part of the fix for [YOCTO #9537]. Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com>
