[TYPO3-core] Documenting usage of Composer manifest

[François Suter]

Hi all,

All system extensions now have a Composer manifest. I thought it would 
be a good idea to document this in Core APIs, but I must admit that I 
miss information about this.

- should a developer include a Composer manifest in his/her extension? 
If yes, why?

- what is the structure of the manifest, in particular the minimum 
information required? The naming conventions?

- what is the relation between ext_emconf.php and composer.json?

- is ext_emconf.php still needed? Is it planned to phase it out?

Thanks in advance for the explanations.

Cheers
