function domain_init in Domain Access 7.3

Same name and namespace in other branches

1. 5 domain.module \domain_init()
2. 6.2 domain.module \domain_init()
3. 7.2 domain.module \domain_init()

Implements hook_init().

Initializes a global $_domain variable if necessary (usually that's done in domain_bootstrap.inc) and loads information on current domain.

Also handles www stripping, checks the validity of user domains and updates $conf['site_name'].
