run-tests: move diff generation into TestResult
TestResult is the thing that captures all our test results. It's logical
for diff viewing to be handled there and not inside Test.
While writing this patch, it was discovered that Test.fail() was
printing redundant test result output. This has been removed.
Arguments controlling diffs have been removed from Test.__init__.
run-tests: remove global abort flag
The global abort flag has been moved into each Test instance. A
Test.abort() accomplishing the same thing has been added.
merge: add conflict marker formatter (BC)
Adds a conflict marker formatter that can produce custom conflict marker
descriptions. It can be set via ui.mergemarkertemplate. The old behavior
can be used still by setting ui.mergemarkers=basic.
The default format is similar to:
{node|short} {tag} {branch} {bookmarks} - {author}: "{desc|firstline}"
And renders as:
contextblahblah

run-tests: remove options from Test.__init__
All options are now passed as arguments and we no longer need options.
This enables us to instantiate Test from "plain old data" types. Since
options must be given as arguments, it also makes people think harder
about adding things that may not belong in Test. This will help ensure a
proper separation of responsibility going forward.
run-tests: refactor port number declaration
Instead of making port numbers derived from count and a global initial
port, we now pass a start port to Test.__init__ and do the calculation
at a higher level.
