media_access() has been removed

The media_access() function has been removed in favor of the File Entity access API introduced in #1227706: Add a file entity access API.

Modules that previously relied on media_access() can either switch to file_entity_access() or, if they need to provide compatibility with both Media 1.x and 2.x can include their own wrapper function.

Before:

media_access('create', $account);

After:

file_entity_access('create', NULL, $account);

Wrapper around both media_access() and file_entity_access():

/**
 * Determine if a user may perform the given operation on the specified file.
 *
 * Enables compatibility with Media 1.x and 2.x by providing a wrapper around
 * both media_access() and file_entity_access().
 *
 * @return boolean
 *   TRUE if the operation may be performed, FALSE otherwise.
 *
 * @see media_access()
 * @see file_entity_access()
