/**
* Generates an internal or external URL.
*
* When creating links in modules, consider whether l() could be a better
* alternative than url().
*
* @param $path
* (optional) The internal path or external URL being linked to, such as
* "node/34" or "http://example.com/foo". The default value is equivalent to
* passing in '<front>'. A few notes:
* - If you provide a full URL, it will be considered an external URL.
* - If you provide only the path (e.g. "node/34"), it will be
* considered an internal link. In this case, it should be a system URL,
* and it will be replaced with the alias, if one exists. Additional query
* arguments for internal paths must be supplied in $options['query'], not
* included in $path.
* - If you provide an internal path and $options['alias'] is set to TRUE, the
* path is assumed already to be the correct path alias, and the alias is
* not looked up.
* - The special string '<front>' generates a link to the site's base URL.
* - If your external URL contains a query (e.g. http://example.com/foo?a=b),
* then you can either URL encode the query keys and values yourself and
* include them in $path, or use $options['query'] to let this function
* URL encode them.
* @param $options
* (optional) An associative array of additional options, with the following
* elements:
* - 'query': An array of query key/value-pairs (without any URL-encoding) to
* append to the URL.
* - 'fragment': A fragment identifier (named anchor) to append to the URL.
* Do not include the leading '#' character.
* - 'absolute': Defaults to FALSE. Whether to force the output to be an
* absolute link (beginning with http:). Useful for links that will be
* displayed outside the site, such as in an RSS feed.
* - 'alias': Defaults to FALSE. Whether the given path is a URL alias
* already.
* - 'external': Whether the given path is an external URL.
* - 'language': An optional language object. If the path being linked to is
* internal to the site, $options['language'] is used to look up the alias
* for the URL. If $options['language'] is omitted, the global $language_url
* will be used.
* - 'https': Whether this URL should point to a secure location. If not
* defined, the current scheme is used, so the user stays on HTTP or HTTPS
* respectively. TRUE enforces HTTPS and FALSE enforces HTTP, but HTTPS can
* only be enforced when the variable 'https' is set to TRUE.
* - 'base_url': Only used internally, to modify the base URL when a language
* dependent URL requires so.
* - 'prefix': Only used internally, to modify the path when a language
* dependent URL requires so.
* - 'script': The script filename in Drupal's root directory to use when
* clean URLs are disabled, such as 'index.php'. Defaults to an empty
* string, as most modern web servers automatically find 'index.php'. If
* clean URLs are disabled, the value of $path is appended as query
* parameter 'q' to $options['script'] in the returned URL. When deploying
* Drupal on a web server that cannot be configured to automatically find
* index.php, then hook_url_outbound_alter() can be implemented to force
* this value to 'index.php'.
* - 'entity_type': The entity type of the object that called url(). Only
* set if url() is invoked by entity_uri().
* - 'entity': The entity object (such as a node) for which the URL is being
* generated. Only set if url() is invoked by entity_uri().
*
* @return string
* A string containing a URL to the given path.
