Make dmtracedump available on windows pc.
Issue Details:
1.
When dmtracedump is executed on windows pc, command failed.
Error message is "ERROR: unable to read xxxxx bytes from trace file".
This is because trace file is opened in text mode.
2.
When dmtracedump outputs html, #0 method's name isn't "(toplevel)" but "(unknown)".
This is because the positions of (toplevel) and (unknown) in method list interchange on windows pc.
3.
Command of generating png file is invalid for windows.
Command example is "dot -Tpng -o 'foo.png' 'foo.dot'".
When it is executed, it failed.
Error message is "Error: dot: can't open foo.dot.".
This is because command prompt of windows can't open file surrounded by single quotation marks.
4.
dmtracedump failed to create temporary dot file on windows.
This is because temporary dot file is created in "/tmp".
"/tmp" doesn't exist on windows.
Solutions:
1.
Open trace file in binary mode.
2.
In order not to exchange the positoin of (toplevel) and (unknown),
we set the id of (toplevel) to -1 and we set the id of (unknown) to -2.
3.
Replace single qutation marks in command of generating png file to double qutation marks.
4.
Create temporary dot file in current directory.

Don't crash if the dmtracedump -d file doesn't exist.

Add a dual clock profiler tracing mode.
Dalvik previously supported using either the thread-cpu clock
or the real time clock as the timebase for profiler traces.
This change adds a dual clock mode where both thread-cpu time
and real time timestamps are collected.
Using dual clock mode significantly improves TraceView ability
to accurately reconstruct the global timeline of events,
particularly on SMP systems.
For now, thread-cpu mode remains the default.
Dual clock mode can be enabled by running the following command
and restarting the system server.
adb shell setprop dalvik.vm.extra-opts -Xprofile:dualclock

Fix dmtracedump.
This rolls back a couple of checkins that were made some time ago. The
dmtracedump tool has largely been broken ever since (only the "-o" mode
worked reliably).
The key feature this removes is "filters". I don't know what they do.

Add option for specifying wall-clock in method profiling.
Normally you want to use the per-thread CPU clock rather than the wall
clock, because (a) it's more useful and (b) traceview goes a little nuts
if you don't. However, it's useful for some performance testing.
The command-line option allows you to switch modes like this:
% adb shell stop
% adb shell setprop dalvik.vm.extra-opts -Xprofile:wallclock
% adb shell start
This also changes the somewhat nebulous "clock=global" trace header line
to "clock=wall". Nothing looks at this anyway so I'm not worried
about breaking compatibility.
While I was in here, I fixed a couple of problems caused by failure to
initialize data structures that made dmtracedump crash (yay valgrind).
Bug 2943229.
(cherry-pick from dalvik-dev)

Fix a couple minor bugs (bug 2404859) in TraceDump.c
1. A switch statement was missing a "break" after option letter "f".
2. The heavily-used function "lookupMethod()" had an expression using mod (%) instead of bitwise-and (&).

Added support for filter in dmtracedump tool, along with some test cases.
Some corner cases are still not handled in the code, but will be eventually.

The thread profile lists all the running threads, sorted by elapsed time.
