Donating core DukeScript presenters to Apache NetBeans

[dukescript]

This is a pull request that donates the core DukeScript presenters to HTML/Java subproject of Apache NetBeans. Following modules are being donated:

• render - a way to start a browser - using native GTK (on Linux and Mac OS X), AWT or CLI
• generic - ProtoPresenterBuilder & co. - core implementation of a presenter that handles connection between JavaScript VM and Java VM via a textual protocol - very portable
• browser - uses of ProtoPresenterBuilder to start a local server and let a browser connect to it
• webkit - native presenter for Linux and Mac OS X that uses WebKit via JNA

Certain functionality in Apache NetBeans requires HTML/Java and that right now needs JavaFX. With the help of these presenters, the dependency on JavaFX could be made optional.

There was an interest in the Apache NetBeans community to create a presenter that would display inside of VSCode - the browser presenter should be enough for such task.

👍 Thank you for doing this! You might be my new best friend. 😄 I'd recently been considering (again) whether to look at reimplementing these under Apache.

Re. the travis failures - the build was failing in master as well - fixed in 75e792f - please merge and re-try.

Hi, I think we must go through https://incubator.apache.org/ip-clearance/ process.

[geertjanw]

I think it’s just like any other code that anyone else has written for Apache NetBeans.

[neilcsmith-net]

@ebarboni maybe bring that up as a general discussion point on dev@ ? Reading the link I think you have a point. On the other hand, we've integrated far bigger contributions by PR already without doing that.

[ebarboni]

IT come to my mind because dukescript is like codehaus , and we had to do the IP clearance to be able to take over. Not sure others PR where in this case.

[geertjanw]

It’s the same as Payara or Kotlin — simply a pull request is all that was done, just like any code contribution.

[neilcsmith-net]

@geertjanw those are two of the PRs I'm thinking of that judging from @ebarboni link should possibly also have gone through IP clearance. Still suggest we discuss on dev@ so we have a consistent approach on this, rather than here.

[geertjanw]

Sounds good, I'll agree either way we decide. :-)

[jtulach]

Make sure .sigtest artifact is generated for new projects.

I am fine with the technical side of the contribution. @ebarboni, once you are fine with legal aspects, please press the merge button.

[ebarboni]

@JaroslavTulach voting for acceptance started. mailed @dukescript to see if a Software Grant is applicable.

@JaroslavTulach, @dukescript
is the following page correct to your point of view ?
http://incubator.apache.org/ip-clearance/netbeans-dukescript-presenters.html

[ebarboni]

Hi @JaroslavTulach @dukescript , I'm not very good at PR management is it somehow possible to make this PR only one commit to help having just one hash to facilitate donation review ?
All paperwork are set, just this final move may help tracability

[JaroslavTulach]

I am not fan of squashing, especially if the only reason is legal. Just use the last hash:
383122e it uniquely identifies all the previous history - in case you want to see changes, invoke git diff -r 75e792f9b2...383122e.

[ebarboni]

ok thanks, I guess the hash is enough

[ebarboni]

@JaroslavTulach you can merge at any time, IP clearance vote pass
