function domain_bootstrap in Domain Access 7.2

Same name and namespace in other branches

1. 6.2 domain.bootstrap.inc \domain_bootstrap()
2. 7.3 domain.bootstrap.inc \domain_bootstrap()

Domain module bootstrap: calls all bootstrap phases.

Effectively, we add our own bootstrap phase to Drupal core. This allows us to do selective configuration changes before Drupal has a chance to react. For example, the Domain Conf module allows page caching to be set to "on" for example.com but "off" for no-cache.example.com.

The big issues here are command-line interactions, which are slightly different; and the fact that drupal_settings_initialize() is needed to properly hit the page cache.

The initial check for GLOBALS['base_root'] lets us know that we have already run the normal configuration routine and are now free to alter settings per-domain.

Note that this problem is largely caused by the need to jump ahead in drupal_bootstrap() in order to have database functions available.
