emerge: fix invalid locale setting (bug 519074)

Don't die when the user has an invalid locale setting.
Resolves bug 519074.
emake: pass EXTRA_EMAKE after user's "$@", not before

Patch allows easier override or ebuild things, like
    #foo-9999.ebuild:
    src_compile() {
        emake V=1
    }

    EXTRA_EMAKE="V=0" emerge =foo-9999

That way it's easier to eyeball upstream builds for new warnings.

This behaviour is more in line with EXTRA_ECONF variable.

Enable consistent __future__ behavior for division

In Python 2, the division ('/') operator defaults to integer
(truncating) division when given integer argument. In Python 3, it
performs floating-point division unconditionally instead. To overcome
this difference and get a consistent behavior, integers were converted
to floats explicitly in a few places.

Instead, use a simpler 'from __future__ import division' statement that
enables floating-point division globally in Python 2. Use it in all
relevant files to get a consistent behavior, and use '//' appropriately
whenever integer division is desired.

Makefile: substitute PORTAGE_BASE_PATH during install.

This is the first step towards disjoining Python module install from
binary install.
self-update: copy only relevant packages from PORTAGE_PYM_PATH.

If Portage is supposed to be installed alongside other Python packages,
it is important that it only tries to backup its own packages rather
than whole site-packages directory.
portage.const: make PORTAGE_PYM_PATH point to real package tree.

Instead of using the canonical location based off PORTAGE_BASE_PATH, use
the root of loaded Python packages directly.
Append .py to runTests so that it could be installed.

As a result, we now are able to run tests against installed Portage.
Rename '__test__' to '__test__.py' to easily install it.
tests: fix running tests on installed copy of Portage.

This involved adding installation paths to configuration files
conditionally and letting repoman fetch metadata.dtd.
tests: fix running import & compile tests on installed copy.
