[OE-core] [RFC PATCH] Switch most global exports to task level

From: Christopher Larson <chris_larson at mentor.com>
The majority of our global exports are only needed for the build tasks, so
switch them to those tasks (configure/compile/install, but not
populate_sysroot or package).
Kept global exports: PATH, PSEUDO_DISABLED, LC_ALL, CCACHE_DIR, CCACHE_DISABLE
The variables which are exported by default are listed in logically grouped
variables, to make it easy to add or remove them from task exports:
- PKG_CONFIG_EXPORTS: PKG_CONFIG_DIR, etc
- BUILD_EXPORTS: BUILD_CC, etc
- TARGET_EXPORTS: TARGET_CC, etc
- TARGET_PATH_EXPORTS: prefix, bindir, etc
Intermediate variables are added as well, to ease usage and avoid the need to
mess with the flags directly for the common cases:
- CONFIGURE_EXPORTS
- COMPILE_EXPORTS
- INSTALL_EXPORTS
- POPULATE_SYSROOT_EXPORTS
- PACKAGE_EXPORTS
Future patches will pare down the exports from here. Specifically removing the
default export of BUILD_EXPORTS, TARGET_EXPORTS, and TARGET_PATH_EXPORTS, none
of which are consistently used by the buildsystems we're calling into.
This is placed into conf/task-exports.conf, to avoid cluttering up
bitbake.conf any further.
