Add functioncallcount.meta and functioncallcount.stp. Add para-callgraph.stp and para-callgraph.meta. Fixed __stp_get_mm_path() error return code. diagnostics improvement: print arch/mach at top if -vv Make _vfs.generic_commit_write only for kernel<=2.6.25 Handles "mortally wounded" threads correctly when detaching. further clarify that elfutils need not be absolutely freshest, nor rebuilt every time point out releases/ directory; clarify optionality of elfutils bundling Add auto_free_ref to auto_free stuff; bug 6694
