Bring r20651 & r20652 from trunk to 1.8 branch:
Switch from using 'pthread_create' to 'pthread_self' when trying to
detect the pthread library, so that the Intel C compiler is happier with the
prototype.
Teach the tracing script & routines about the 'unsigned long' and
'unsigned long long' types, so that the H5Pset_fapl_log() API routine gets
tracing information correct.
Tested on:
FreeBSD/32 6.3 (duty)
(h5committested on trunk)
