Load a media object from a given URI

Without this function in a release, I suspect we'll begin to see some otherwise unnecessary code duplication in all the provider files (youtube, vimeo, flickr, brightcove, etc), as we begin to pull in remote streams that haven't yet been saved to the db. Thus, I'm bumping it up to major.

However, as it's not used in the core of Media, it's a little tricky to review. I suggest using the devel module, with something like the following at /devel/php (assuming the Media: YouTube module is installed). Test it both before and after adding the media to the database.

  dpm(media_uri_to_object('youtube://v/lZ-s3DRZJKY'));

While we're at it, perhaps we need to follow the core model for entities (at least nodes) and add ->is_new or some other flag if the object doesn't currently exist in the db...

though that likely belongs in file_uri_to_object().

for that matter, file_uri_to_object() should probably take care of all this anyway. it's been over a year, and i brought that up at http://drupal.org/node/685818. too bad we didn't push that more in core...

thinking about it more, i think we need to push all of this into file_uri_to_object(). then that will be the callback of choice, and as it already exists in the module, it won't cause as many issues going forward. new patch forthcoming.

this patch moves it to file_uri_to_object() and adds ->is_new when needed. i'll update the core issue as well, though it's obviously too late to include that there for d7.

The cool thing is that this change should also make it easier to get rid of that annoying "You have entered a URL for a video that is already in your library." message.

this should be testable as well. not necessary for a release obviously. updating the tags.

yes, that would be acceptable. thanks, @effulgentsia. should be safe in my use-case, as the file objects shouldn't be saved at that point in the game.
