Subject: [PATCH] Initialize component globals before threads globals
An earlier commit (979e80136) swapped the order of initializing
globals and threads. This caused issues with the perf_event, appio,
and stealtime components which could be observed with the
all_native_events, appio_test_pthreads, and stealtime_basic tests
respectively. The component initialization needs to be performed
before the thread initialization.
The order of initialization has been changed back to initializing the
component then the threads. One complication is that papi_internal.c
had functions (_papi_hwi_set_papi_event_code and
_papi_hwi_get_papi_event_code) that required thread local storage that
was being setup in commit 979e80136 by the thread initialization.
This was the original reason for swapping the order of initialization
of component and thread. Using __thread on the file scope
declarations of the variables allow the original order of
initialization.
