rename to buildEntry and also pass name as arguments

[smelukov]

addEntry is not the same that buildEntry
addEntry will be called when adding an entry. This need to calculate total entries
buildEntry will be called when the module for an entry will be built
Or what do you mean? :)

It would be much more useful if the handler took raw data (as an object or arguments in a particular order), rather than pre-made strings. E.g. in my implementation of a progress bar using the ProgressPlugin I have to resort to regexps/splits to re-parse the data out of the strings in order to be able to position them:

If instead we provided a default handler that makes these strings above, we can get the same behavior, and still give greater flexibility to consumers, alternative handlers.

I would imagine handler being most flexible e.g. when called like this:

handler({compilerIndex, currentStage, doneModules, activeModules, lastModulesCount, moduleCount, count, mode})

And some of those parameters would obviously be undefined in certain stages (which is fine). By stage I mean the hook currently being executed, or compilation.

@niieani Seems like this is a breaking change, but in this PR I don't want to make any breaking changes
I think you may create your own PR for this feature to the next-branch

@sokra Seems like it's broken by this change
I've set entries to true and got 68% building 198/804 entries 2050/2115 modules 65 active .....
198/804 is not 68%
It should be Math.min - https://github.com/webpack/webpack/blob/master/lib/ProgressPlugin.js#L138
