#225880 by pwolanin, keith.smith: get the user create settings.php instead of Drupal, so upgrading getseasier

#50901 by chx: do not allow user login under maintenance mode, if the logged in user has no site config permission

 - whitespaces at end of lines
 - indentation
 - control structure usage
 - whitespace in empty lines
 - phpdoc comment formatting

#141727 by merlinofchaos, dvessel, sun: restore themeability support for maintenance pages (regression)

#173408 by markus_petrux / add1sun: move proxy IP configuration options to settings.php, because these need to be used before Drupal has the variables loaded from the database

#190283 by myself and JirkaRbyka: use get_t() in pre-database setup code, add missing javascript key to language objects (kills notices) and document st() better

#182675 by chx: fix caching bootstrap, so hook_boot() and the timer is called when required, integrating the cache init function right into the bootstrap

#163785 by Eaton, dvessel and quicksketch: theme .info files should be able to override core and module CSS files based on file basenames

#172262 by JirkaRybka: better globals handling in install system, so the choosen profile and language are remembered

#173227 by Desbeers: make language listing work early in the bootstrap, when modules are not yet loaded (fix a regression from a previous patch)

 - make searches work again, better worded
 - do not cache English stuff
 - fix strike through on string seek page
 - fix exports for translations

#151868 by chx: avoid using array_shift() because it takes a lot of time to rehash the array, so indexing the array is more performant, then shifting items one by one

#171606 by Heine: ported security fix from Drupal 4.7/5; use SCRIPT_NAME instead of PHP_SELF in links to avoid XSS holes

#170638 by JirkaRybka and chx: move update access variable to settings.php, so we can check whether it is wide open, and we have one place for settings

  This is a small form API extension (doesn't break existing code) that
  facilitates the Drupal 6 upgrade of the Views module.  A good example
  of why it can be beneficial to start upgrading your modules early on in
  the code freeze. ;)

#160107 by JohnAlbin: use the same session ID regardless of the protocol used to access the page (eg share sessions between http and https pages)

#125533 by keve: do not continue bootstrap if the process was called back with a phase already executed

#82499 by Jose A Reyero and a little bit from myself: send emails localized in the language needed in specific situations, and centralize mail composing operations with hook_mail()
