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.

test command parsing and dispatch

  $ hg init a
  $ cd a

Redundant options used to crash (issue436):
  $ hg -v log -v
  $ hg -v log -v x

  $ echo a > a
  $ hg ci -Ama
  adding a

Missing arg:

  $ hg cat
  hg cat: invalid arguments
  hg cat [OPTION]... FILE...
  
  output the current or given revision of files
  
  options ([+] can be repeated):
  
   -o --output FORMAT       print output to file with formatted name
   -r --rev REV             print the given revision
      --decode              apply any matching decode filter
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
  
  (use 'hg cat -h' to show more help)
