bz6436 backtraces from uprobes
This implements proper unwinding from uprobes in the presence of
uretprobe trampolines.
* runtime/stack.c (_stp_stack_print): Rework for uprobe context case
and refactor a bit.
* runtime/uprobes2/uprobes.h (GET_PC_URETPROBE_NONE): new constant
* runtime/uprobes2/uprobes.c (uprobe_get_pc): Support translating the
trampoline function from uprobe context in addition to uretprobe
context.
* runtime/uprobes/uprobes.h (GET_PC_URETPROBE_NONE): ditto
* runtime/uprobes/uprobes.c (uprobe_get_pc): ditto
* tapsets.cxx (uprobe_derived_probe_group::emit_module_decls):
Initialize ri in context to GET_PC_URETPROBE_NONE in generated
enter_uprobe_probe.
* testsuite/systemtap.context/fib.stp: Add an option to do a backtrace
on function entry.
* testsuite/systemtap.context/fib.exp: Test backtrace in function
entry (uprobe) probes.
