New API to set default thread attributes

Browse Source 
This patch introduces two new convenience functions to set the default
thread attributes used for creating threads.  This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.

* On Linux, the clock function now uses the clock_gettime system call
for improved precision, rather than old times system call.
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.

Each attribute test is a set of two functions, viz. a function to set the
default attribute (do_foo_test) and another to verify its result
(verify_foo_result). Each test spawns a thread and checks (1) if the
attribute values were applied correctly and (2) if the change in the default
value reflected. */
