Missing a lot of the functions from D6 version!

When looking to see if there is a starts_with in the Drupal-7.x-1.2 build, I couldn't find it. Then I decided to compare what functions were in which version. Found some differences. Would make the documentation simpler to keep track of this should they both have the same functions. And this would help expediate moving code which are dependant on this to the next version of Drupal, which is a goal for any API module, in my mind.

Below are my command line executions to see what functions exist. Comments have been manually removed from the 6.x one.
