run-tests: pass abort into Test.__init__

run-tests: pass temp dir into Test.__init__ This patch starts a mini series of moving arguments to Test.__init__ from semi-complex data structures (such as the command options) to named arguments. This will allow Test instances to be more easily instantiated from other contexts. This improves the ability to run Mercurial tests in new and different environments.

update: show message when a bookmark is activated by update When updating to a bookmark, mention that the bookmark is now active. This is a reminder that update does not move the current bookmark if an explicit target is given - instead it activates that target.

run-tests: pass a full test path into Test.__init__ Previously, a Test's path came from the base directory of all tests and a filename leaf. There is not a strong reason why an absolute test path can not be specified. This change isn't strictly necessary. But it does enable scenarios such as more easily running tests from multiple, non-sibling directories.

run-tests: factor refpath into Test classes refpath is a side-effect of the test type. We therefore move it to the Test class implementations.

run-tests: don't trap exceptions in Test.runTest() Exceptions are all handled in Test.run(). This code was redundant since the unittest test wrapper class was merged into Test.

run-tests: factor options out of run() We were only utilizing 2 parts of options. These have been converted to named arguments.

convert: mercurial source: convert global tags only - not local tags Mercurial tags can be local (tag -l, stored in .hg/localtags) or global (normal tags, tracked in .hgtags) ... or extensions can add other kind of tags. Convert would take all tags (except "tip"), not just the ones from .hgtags, and put them into .hgtags. Instead, convert only the global tags that come from .hgtags.

run-tests: refactor temporary directories in Test We no longer need cleanup() because setUp() and tearDown() cover it. We move tempdir creation into setUp() and always delete in tearDown()

run-tests: move _executetests into TestSuite
