[gentoo-portage-dev] [PATCHES] Random issues and refactoring before EAPI6 series

[Michał Górny]

dol-sen asked me to send all of them in a serie. Those are minor
bugfixes and code refactoring done to prepare for EAPI6 code.

1 & 2 cleans up econf. In EAPI6 we will likely be adding --docdir
and --htmldir there, so we should add it in nice code rather than
copying the bad one.

3-4 aim to clean up EAPI handling a bit. It's far from perfect, but 3 at
least fixes the bug that EAPI 5 is considered unsupported. Further
changes can be done in the future.

5 fixes PMS incompatibility that causes 'nonfatal' to prevent 'die' from
working correctly. I'm pretty sure the bug was mentioned by PMS team
already but nobody considered it important enough to report a bug. EAPI
6 'nonfatal die' support will land in place of that conditional.

6 aims to simplify the phase setting function that is hard to understand
and the moment, and has a few unnecessary, hard-to-understand side
effects like declaring non-existent __eapi2_src_*() phases. The new code
is much cleaner and makes adding new phases in future EAPIs trivial. It
also prevents from calling default_* function for another phase as
forbidden by PMS.
