Some vendor would like to have different crash management policy for debug and release image. Thus, Tizen will provide crash-manager debug and release package. This patch is the preparation for the package separation. In case of crash-manager debug, following CFLAGS will be enabled. export CFLAGS+=" -DTIZEN_ENGINEER_MODE" export CFLAGS+=" -DTIZEN_ENABLE_COREDUMP" In the future, export CFLAGS+=" -DTIZEN_DEBUG_ENABLE" may be added. Basically, default Tizen image will include crash management policy for debug mode. cf) .debugmode file will be used for just crash-popup control for 3.0 compatibility.

Commit 82e3caa86 ("crash-stack: Find crashed tid by wchan") introduced heuristic method of finding correct thread id, if it was not passed by the kernel as parameter to crash-manager. This commit modifies this heuristic to also consider "pipe_wait" function in kernel to signify crashed thread. This is what was observed to be true on aarch64.
