Merge branch 'gtod'

Add a testcase for gtod init/kill
This test simply checks that _gettimeofday_init and _gettimeofday_kill
are pulled in when gettimeofday is used, and also that they are NOT
pulled in when gettimeofday is not used.
commit 5780cc7f8208ebca519d6e076fe403b1220ab865

Add selective use of _stp_time_init/kill (PR9822)
Our gettimeofday runtime has frequent wakeups to stay in sync with
kernel time, but this is wasted effort if gettimeofday is not used in
the script. This patch moves the calls to _stp_time_init and
_stp_time_kill into begin and end/error probes, which only get pulled in
if one of the gettimeofday variants is called.
