Bug#925211: uglifyjs conflicts with webpack which can hinder JS maintainers work

Hi,

it takes some time to understand what's happening here, and since
fixing it properly will require quite some work on multiple packages,
i add my notes to this bug report.

Nota Bene: i use "webpack" here but the sake of the example.

# Situation
Because uglify version 2 compiles software that uglify version 3 does not
compile
correctly, and vice-versa, there are two versions in debian:
* uglifyjs-2.8.29 builds node-uglify which provides uglifyjs
* uglify-js-3.4.9 builds uglifyjs

# Solutions (in my order of preference, to be adapted)
1. Packages not building with uglifyjs 2 should be fixed to build with
uglifyjs 3.
Not a trivial thing to do and it's deep freeze now.

2. Distribute /usr/bin/uglifyjsN and fix all packages calling
/usr/bin/uglifyjs to call
uglifyjsN, when they can't be fixed to use latest version of
/usr/bin/uglifyjs.

# Slight improvement that might be done for buster
IF apt behaves like i think it will, to allow both /usr/bin/uglifyjs and
node-uglify
package to be installed:
* uglify-js-3.4.9 builds node-uglify-js which provides uglifyjs and
conflicts uglifyjs (<< 3.5.0-2),
and remove uglifyjs binary package (to get it to be pure virtual package).

However, if dependencies both try to install node-uglify and node-uglify-js
it will still fail,
but it's not as bad as a direct conflict with /usr/bin/uglifyjs.
It could be misleading, though, to have an unexpected version, so maybe the
best thing
is to do nothing for Buster.

Jérémy
