Issue:
When libmysqld/example/mysql_embedded is executed, it was getting abort. Its a
regression as it was working in 5.1 and failed in 5.5. Issue is there because 
remaining_argc/remaining_argv were not getting assigned correctly in 
init_embedded_server() which were being used later in init_common_variable().

Solution:
Rectified code to pass correct argc/argv to be used in init_common_variable().
