#330983 by recidive and boombatower: Rename users/users_roles tables to user/user_role for consistency.

- Patch #311160 by moshe weitzman and Damien Tournoud: enhance run-tests.sh by automatically picking up the PHP interpreter.

- Patch #302763 by Dave Reid, Rob Loach: replace time() by ['REQUEST_TIME'] as per Rasmus' suggestion.  Removed drupal_referrer() for consistency.

- Patch #254166 by boombatower: improve and clean-up the test script.  Added color coding and allow people to control the verbosity.

- Patch #243773 by chx, catch, boombatower, cwgordon7, yched, dmitrig01, et al: small revert of batch API patch.  Also forgot to mention cwgordon7 in the previous commit.

- Patch #243773 by chx, catch, boombatower, yched, dmitrig01, et al: use the batch API for running the tests instead of an all-in-one approach.  Great work.

- Patch #254166 by boombatower and pwlonin: added --list feature to list all available test groups and fixed some indentation issues.

  Drupal core!  This is an important milestone for the project so enable
  the module and check it out ... :)

  Thanks to Rok Žlender, Károly Négyesi, Jimmy Berry, Kevin Bridges, Charlie
  Gordon, Douglas Hubler, Miglius Alaburda, Andy Kirkham, Dimitri13, Kieran
  Lal, Moshe Weitzman, and the many other people that helped with testing
  over the past years and that drove this home.

  It all works but it is still rough around the edges (i.e. documentation
  is still being written, the coding style is not 100% yet, a number of
  tests still fail) but we spent the entire weekend working on it in Paris
  and made a ton of progress.  The best way to help and to get up to speed,
  is to start writing and contributing some tests ... as well as fixing
  some of the failures.

  For those willing to help with improving the test framework, here are
  some next steps and issues to resolve:

    - How to best approach unit tests and mock functions?
    - How to test drupal_mail() and drupal_http_request()?
    - How to improve the admin UI so we have a nice progress bar?
    - How best to do code coverage?
    - See http://g.d.o/node/10099 for more ...

  This is a big and important patch for Drupal's security.  We are switching
  to much stronger password hashes that are also compatible with the Portable
  PHP password hashing framework.

  The new password hashes defeat a number of attacks, including:

  - The ability to try candidate passwords against multiple hashes at once.
  - The ability to use pre-hashed lists of candidate passwords.
  - The ability to determine whether two users have the same (or different)
    password without actually having to guess one of the passwords.

  Also implemented a pluggable password hashing API (similar to how an alternate
  cache mechanism can be used) to allow developers to readily substitute an
  alternative hashing and authentication scheme.

  Thanks all!

- Patch #222236 by Rob Loach: drupal.sh with no arguments now prints the help text instead of giving an error.

- Patch #59863 by sun et al: added a scripts/drupal.sh to execute Drupal code from the command line.  This is great for using Drupal as a scripting framework, or to write backup or migration scripts.
