[development] module_exists vs. functions_exists?

[Aaron Winborn]

Doesn't work in many cases. I frequently build modules with optional 
dependencies. Even with your set up, we're assuming a module's api stays 
the same within a core version, which is frequently not true.

There's no easy answer for the first case, other than bloating your code 
with additional drupal_function_exists checks, and the second would 
require tracking module version (at least its major version).
