Rename *.l files to *.re
This syncs PHP lexer files to all use *.re extension. The *.re files are processed with the RE2C tool.

-/* How it works (for the core ini directives):
- * ===========================================
- *
- * 1. Scanner scans file for tokens and passes them to parser.
- * 2. Parser parses the tokens and passes the name/value pairs to the callback
- * function which stores them in the configuration hash table.
- * 3. Later REGISTER_INI_ENTRIES() is called which triggers the actual
- * registering of ini entries and uses zend_get_configuration_directive()
- * to fetch the previously stored name/value pair from configuration hash table
- * and registers the static ini entries which match the name to the value
- * into EG(ini_directives) hash table.
- * 4. PATH section entries are used per-request from down to top, each overriding
- * previous if one exists. zend_alter_ini_entry() is called for each entry.
- * Settings in PATH section are ZEND_INI_SYSTEM accessible and thus mimics the
- * php_admin_* directives used within Apache httpd.conf when PHP is compiled as
- * module for Apache.
- * 5. User defined ini files (like .htaccess for apache) are parsed for each request and
- * stored in separate hash defined by SAPI.
- */
-
-/* TODO: (ordered by importance :-)
- * ===============================================================================
- *
- * - Separate constant lookup totally from plain strings (using CONSTANT pattern)
- * - Add #if .. #else .. #endif and ==, !=, <, > , <=, >= operators
- * - Add #include "some.ini"
- * - Allow variables to refer to options also when using parse_ini_file()
