This CL adds --apk-dir option, which specifies the directory
that contains APK files to be installed before measuring
boot time.

'sf_stop_bootanim' is useful for tracking the time wasted by
showing the 'outro' part of the boot animation.
'wm_boot_animation_done' is also useful for tracking user
perceived boot time.

This creates the concept of 'event_trigger' vs 'property_trigger'
Previously these were merged into one, such that 'on property:a=b &&
property:b=c' is triggered when properties a=b and b=c as expected,
however combinations such as 'on early-boot && boot' would trigger
during both early-boot and boot. Similarly, 'on early-boot &&
property:a=b' would trigger on both early-boot and again when property
a equals b.
The event trigger distinction ensures that the first example fails to
parse and the second example only triggers on early-boot if
property a equals b.
This coalesces Actions with the same triggers into a single Action object

Adds a C++ tokenizer along with unit tests.
This tokenizer will replace the current C implementation
which does a poor job of keeping track of pointers.
This CL is a prerequisite for up coming changes to
the parser. This CL does not wire up this tokenizer and
changes no exsiting code. All that builds is the unit tests.

TEST: Unit tests all pass. No leaks under valgrind
BUG: 22843198
perfboot.py repeats the record of each event log during Android
boot specified times. By default, interval between measurements
is adjusted in such a way that CPUs are cooled down sufficiently
to avoid boot time slowdown caused by CPU thermal throttling.
This script also works around the issue of dropbox slowing down
boot time on userdebug build (http://b/20890386) by limiting
the number of files to be created by dropbox.
The result is output in a tab-separated value format.

This CL adds a trigger and a service so that Systrace can be used
for tracing events during boot.
persist.debug.atrace.boottrace property is used for switching on
and off tracing during boot. /data/misc/boottrace/categories
file is used for specifying the categories to be traced.
These property and file are rewritten by Systrace when the newly
added option --boot is specified.
Here is an example of tracing events of am and wm catetories
during boot.
$ external/chromium-trace/systrace am wm --boot
This command will cause the device to reboot. Once the device has
booted up, the trace report is created by hitting Ctrl+C.
As written in readme.txt, this mechanism relies on persistent
property, so tracing events that are emitted before that are not
recorded. This is enough for tracing events after zygote is
launched though.
This only works on userdebug or eng build for security reason.

TEST: Tested importing a folder on arm64 emulator
It is only a temporary fix. I hope the code can be moved into a member
function of class Command.

Instead, run the command only when sys.powerctl is set to
"shutdown,userrequested". This way, we can avoid running
fsck when shutdown is triggered due to a low power state.
This is a follow-up CL for http://r.android.com/158525.
