Patch for special treatment of install hooks -- required for taxonomy integration

This is a patch that adds special support for feature exports that provide code for "hook_enable" and "hook_disable", like the Exportables module does for taxonomy vocabulary and terms.

Basically, since taxonomy vocabulary and terms don't have real default hooks, Exportables emulates this by syncing to the database during hook_enable and hook_disable. This is all fine, except that Exportables provides (or rather, will provide once this patch is finalized and accepted: #645596: Patch to export taxonomy terms) two seperate components: taxonomy_vocabulary and taxonomy_term. If they are both used in the same feature, "hook_enable" and "hook_disable" will be written twice, creating a name conflict.

So, this patch causes the following to happen:

• A mymodule.install file will be created (but only for modules that don't already exist, just like mymodule.module) that defines a "hook_enable" and "hook_disable" which simply include "mymodule.features.inc" and call "_mymodule_enable" and "_mymodule_disable". Here is an example generated using the patch:
  

  /**
   * Implementation of hook_enable().
   */
  function mymodule_enable() {
    module_load_include('inc', 'mymodule', 'mymodule.features.inc');
    $args = func_get_args();
    return call_user_func_array('_mymodule_enable', $args);
  }
  
  /**
   * Implementation of hook_disable().
   */
  function mymodule_disable() {
    module_load_include('inc', 'mymodule', 'mymodule.features.inc');
    $args = func_get_args();
    return call_user_func_array('_mymodule_disable', $args);
  }
  

• The hook implementation for each component will be renamed to include the component name, ie. mymodule_enable_taxonomy_vocabulary() and mymodule_enable_taxonomy_term(). There are otherwise treated normally.
• A _mymodule_enable() and _mymodule_disable() will be put mymodule.features.inc which calls all component enable and disables. For example, here is _mymodule_enable() as generated by the patch:
  

  /**
   * Helper to implementation of hook_enable().
   */
  function _mymodule_enable() {
    mymodule_enable_taxonomy_term();
    mymodule_enable_taxonomy_vocabulary();
  }
  

  One random note about the above, these are listed in the inverse logical order: vocabularies should happen before terms. But I'm not sure how to deal with that yet, but this patch is a first step to this working at all..

Please let me know what you think. There are probably bugs or issues I didn't think of with the patch.

Thank you,
David.
