Dump stack trace on emulator test failure
Emulator test failures are sometimes hard to debug, especially when the
test is stuck somewhere and times out. Let's have the emulator dump
stack trace when an assertion fails or a test times out.
The produced stack trace is in this format:
#0 build/host/kb_8042/kb_8042.exe() [0x412421]
/home/victoryang/trunk/src/platform/ec/test/kb_8042.c:104
#1 build/host/kb_8042/kb_8042.exe() [0x4124a9]
/home/victoryang/trunk/src/platform/ec/test/kb_8042.c:129
#2 build/host/kb_8042/kb_8042.exe(run_test+0x3a) [0x412e2c]
/home/victoryang/trunk/src/platform/ec/test/kb_8042.c:262
#3 build/host/kb_8042/kb_8042.exe(_run_test+0x11) [0x4061de]
/home/victoryang/trunk/src/platform/ec/core/host/task.c:90
#4 build/host/kb_8042/kb_8042.exe(_task_start_impl+0x79) [0x406b72]
/home/victoryang/trunk/src/platform/ec/core/host/task.c:408
#5 /lib64/libpthread.so.0(+0x70b1) [0x7f6dc2fa10b1]
??:0
#6 /lib64/libc.so.6(clone+0x6d) [0x7f6dc2cd8efd]
??:0
The file name and line number in the trace is generated by addr2line.
