Anurag Kar f27db1f241 pthread : Add support for attributes and few APIs
This introduces the following changes :
    * Implmentation added for pthread attribute related functions :
        * pthread_attr_init
        * pthread_attr_destroy
        * pthread_attr_setdetachstate
        * pthread_attr_getdetachstate
        * pthread_attr_getstacksize
        * pthread_attr_setstacksize
    * pthread_create now supports passing attributes/configs through pthread_attr_t structure
    * pthread_mutex_timedlock added
    * pthread_exit added
    * memory for joinable thread is freed before returning from pthread_join
