run-tests: support multiple cases in .t test

Sometimes we want to run similar tests with slightly different
configurations. Previously we duplicate the test files. This patch
introduces special "#testcases" syntax that allows a single .t file to
contain multiple test cases.

Defined cases could be tested using "#if".

For example, if a test should behave the same with or without an
experimental flag, we can add the following to the .t header:

    #testcases default experimental-a
    #if experimental-a
      $ cat >> $HGRCPATH << EOF
      > [experimental]
      > feature=a
      > EOF
    #endif

The "experimental-a" block won't be executed when running the "default" test
case.

  $ hg init base

  $ cd base
  $ echo 'alpha' > alpha
  $ hg ci -A -m 'add alpha'
  adding alpha
  $ cd ..

  $ cd work
  $ echo 'beta' > beta
  $ hg ci -A -m 'add beta'
  adding beta
  $ cd ..

  $ cd base

Update --clean to revision 1 to simulate a failed merge:

  $ rm alpha beta gamma
  $ hg update --clean 1
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cd ..
