simpleperf: use libbacktrace_offline static library.
Device may not have libbacktrace_offline shared library, so always
using libbacktrace_offline static library.
Use simpleperf namespace to avoid conflicts with ThreadEntry in
libbacktrace.

Support profiling of shared libs embedded in APKs.
Some APKs contain shared libraries that the linker handles
by mmap'ing directly from their APKs (if the library is
uncompressed and the proper manifest flag is set). With
this patch simpleperf now breaks out samples on a per-li
basis and reports the name of the lib within the APK.
Example output:
Cmdline: /system/xbin/simpleperf record -a sleep 30
Samples: 140672 of event 'cpu-cycles'

Simpleperf: add separate cpu_hotplug_test.

Simpleperf: support branch stack sampling in `simpleperf record`.
This only adds support in simpleperf. Branch stack sampling still
lacks kernel support on arm devices.
Use perf_event.h of bionic in host build, because the perf_event.h
of platform glibc is too old.

Simpleperf: add test about cpu hot-plug.
On device like N7(flo), because of a kernel bug, if a cpu is hotplugged
while there are hardware events monitored not on that cpu, the kernel
arrives in an error state that no further hardware events can be monitored.
This test is used to detect the kernel bug.
