simpleperf: check if dwarf callgraph is supported by kernel before testing.
Move inclusion of poll.h from header files to source files,
as event_selection_set.h is used by cmd_report_test.cpp, which
can be built on windows.

Simpleperf: don't use ioctl(PERF_EVENT_IOC_ENABLE).
Some android kernels(like bullhead/angler) can't handle
ioctl(PERF_EVENT_IOC_ENABLE) correctly when cpu-hotplug
happens. Instead of fixing all of them in kernel, we
can't simply don't use it.

Simpleperf: do stack unwinding while recording.
Dumping user's stack consumes lots of disk space, which makes long period recording
impossible. This patch does stack unwinding before writing to perf.data, so it doesn't
need to save user's stack. Previous behavior is still supported with --post-unwind option.
A record cache is used for online record processing.

Simpleperf: rewrite unsupported logging style.
Previously we can use a ternary operator to choose the log level, like
(error ? LOG(ERROR) : LOG(DEBUG)) << xxx. But as the LOG() macro is about
to change, we can no longer write like this.
This CL also changes some improper log levels and log messages.

Simpleperf: support monitoring existing processes/threads.
Also change the default record freq from 1000 to 4000. Because 1000 seems to be too low.
