Consequently rolled back the workaround in make_rule.py
* Added new indirect rule invocation module for encoding the module to
invoke a rule from as well as the exact name to invoke it by, and
for subsequent invocation.
* Fixed module __test__ rules so they really do execute in a separate
module. Associated tweaks to __test__ in path.jam
[SVN r18427]
for the bug report.
* new/make.jam
(make-target-class.construct): Pass the result through
'virtual-target.register'.
* new/virtual-target.jam
(register): Ignore incidental properties when deciding if targets are
equivivalent.
* test/make_rule.py: Add new test.
[SVN r17701]
* new/build-system.jam: Try to load 'test-config.jam'. If successfull,
don't load site-config.jam/user-config.jam.
* test/BoostBuild.py: Add directory where test is invoked to BOOST_BUILD_PATH,
so that test-config.jam can be dropped to "test" dir.
[SVN r17558]
* new/make.jam
(make): Change name only of the first element in 'generating-rule'
* new/virtual-target.jam
(action.actualize): Pass only first element of action name to
toolset.set-target-variables.
* test/make_rule.py: New test.
