description:
Add a new package-settable variable, INSTALLATION_PREFIX, as discussed
with gavan%NetBSD.org@localhost at pkgsrcCon.

Within the pkgsrc infrastructure, LOCALBASE has two different meanings:

    (1) where the package being built should be installed, and
    (2) where to find previously installed packages.

Most instances of case (2) should be converted to use EVAL_PREFIX,
but there are some cases where this is impossible.  To resolve this,
we preserve LOCALBASE to mean (2) and we create a new variable
INSTALLATION_PREFIX to mean (1).

INSTALLATION_PREFIX is meant to be set some time before bsd.pkg.mk is
included, and provides the value for PREFIX if it's defined, e.g.

        NO_MTREE=               yes
        INSTALLATION_PREFIX=    /

        .include "../../mk/bsd.pkg.mk"

This allows us to remove all cases where PREFIX is explicitly set in
the package Makefile, e.g. Java VM packages, qmail, etc.
