To capture the data, allow the pathops client debugging

The following are currently unused in Android, Google3, Chromium, and Mozilla:
- SkEvent
- SkTime::GetMSecs
- SK_TIME_FACTOR (also unused in Skia)
- SkAutoTime
I left uses of SkMSec more-or-less intact for SkEvent, SkAnimator, and SkInterpolator. SkInterpolator is used in Chromium, so I did not want to change the API. The views/ and animator/ code is crufty, so it didn't seem worthwhile to refactor it. Instead, I added SkEvent::GetMSecsSinceStartup, which is likely to be adequate for use in SampleApp.
I also left SkMSec where it is used to measure a duration rather than a timestamp. With the exception of SkMovie, which is used in Android, all of the uses appear to measure the execution time of a piece of code, which I would hope does not exceed 2^31 milliseconds.
Added skiatest::Timer to support a common idiom in tests where we want to measure the wallclock time in integer milliseconds. (Not used in tests/PathOpsSkpClipTest.cpp because it redefines things in Test.h.)
Removed tabs in tests/StrokerTest.cpp.

Iterating through the 903K skps that represent the
imagable 1M top web pages triggers a number of
bugs, some of which are addressed here.
Some web pages trigger intersecting cubic
representations of arc with their conic
counterparts. This exposed a flaw in coincident
detection that caused an infinite loop. The loop
alternatively extended the coincident section and,
determining the that the bounds of the curve pairs
did not overlap, deleted the extension.
Track the number of times the coincident detection
is called, and if it exceeds an empirically found
limit, assume that the curves are coincident and
force it to be so.
The loop count limit can be determined by enabling
DEBUG_T_SECT_LOOP_COUNT and running all tests. The
largest count is reported on completion.
Another class of bugs was caused by concident
detection duplicating nearly identical points that
had been merged earlier. To track these bugs, the
'handle coincidence' code was duplicated as a
const debug variety that reported if one of a
dozen or so irregularities are present; then it is
easier to see when a block of code that fixes one
irregularity regresses another.
Creating the debug const code version exposed some
non-debug code that could be const, and some that
was experimental and could be removed. Set
DEBUG_COINCIDENCE to track coincidence health and
handling.
For running on Chrome, DEBUG_VERIFY checks the
result of pathops against the same operation
using SkRegion to verify that the results are
nearly the same.
When visualizing the pathops work using
tools/pathops_visualizer.htm, set
DEBUG_DUMP_ALIGNMENT to see the curves after
they've been aligned for coincidence.
Other bugs fixed include detecting when a
section of a pair of curves have devolved into
lines and are coincident.

Use the form SkDebugf("%s", arbitraryString) instead of
SkDebugf(arbitraryString).
Fixes the case where SkString::appendf-ing a string with "%%" and then
printing the string with SkDebugf would cause uninitialized read and
corrupted debug print.

skiatest::Test class is now a simple struct. Some
functionalty, such as counting errors or timing is now
handled elsewhere.
skiatest:Reporter is now a simpler abstract class. The two
implementations handle test errors.
DM and pathops_unittest updated.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.

Add skiatest::Failure to keep track of data about a test failure.
Reporter::reportFailed and ::onReportFailed now take Failure as a
parameter. This allows the implementation to treat the failure as it
wishes. Provide a helper to format the failure the same as prior to
the change.
Update the macros for calling reportFailed (REPORTER_ASSERT etc) to
create a Failure object.
Convert a direct call to reportFailed to the macro ERRORF.
Write Failures to Json.
Sample output when running dm on the dummy test crrev.com/705723004:
{
"test_results" : {
"failures" : [
{
"condition" : "0 > 3",
"file_name" : "../../tests/DummyTest.cpp",
"line_no" : 10,
"message" : ""
},
{
"condition" : "false",
"file_name" : "../../tests/DummyTest.cpp",
"line_no" : 4,
"message" : ""
},
{
"condition" : "1 == 3",
"file_name" : "../../tests/DummyTest.cpp",
"line_no" : 5,
"message" : "I can too count!"
},
{
"condition" : "",
"file_name" : "../../tests/DummyTest.cpp",
"line_no" : 6,
"message" : "seven is 7"
},
{
"condition" : "1 == 3",
"file_name" : "../../tests/DummyTest.cpp",
"line_no" : 14,
"message" : "I can too count!"
}
]
}
}
Report all of the failures from one test.
Previously, if one test had multiple failures, only one was reportered.
e.g:
Failures:
test Dummy: ../../tests/DummyTest.cpp:6 seven is 7
test Dummy2: ../../tests/DummyTest.cpp:10 0 > 3
test Dummy3: ../../tests/DummyTest.cpp:14 I can too count!: 1 == 3
3 failures.
Now, we get all the messages:
Failures:
test Dummy: ../../tests/DummyTest.cpp:4 false
../../tests/DummyTest.cpp:5 I can too count!: 1 == 3
../../tests/DummyTest.cpp:6 seven is 7
test Dummy2: ../../tests/DummyTest.cpp:10 0 > 3
test Dummy3: ../../tests/DummyTest.cpp:14 I can too count!: 1 == 3
3 failures.
(Note that we still state "3 failures" because 3 DM::Tasks failed.)

SkTaskGroup is like SkThreadPool except the threads stay in
one global pool. Each SkTaskGroup itself is tiny (4 bytes)
and its wait() method applies only to tasks add()ed to that
instance, not the whole thread pool.
This means we don't need to bring up new thread pools when
tests themselves want to use multithreading (e.g. pathops,
quilt). We just create a new SkTaskGroup and wait for that
to complete. This should be more efficient, and allow us
to expand where we use threads to really latency sensitive
places. E.g. we can probably now use these in nanobench
for CPU .skp rendering.
Now that all threads are sharing the same pool, I think we
can remove most of the custom mechanism pathops tests use
to control threading. They'll just ride on the global pool
with all other tests now.
This (temporarily?) removes the GPU multithreading feature
from DM, which we don't use.
On my desktop, DM runs a little faster (57s -> 55s) in
Debug, and a lot faster in Release (36s -> 24s). The bots
show speedups of similar proportions, cutting more than a
minute off the N4/Release and Win7/Debug runtimes.

Share command flags between dm and unit tests.
Also, allow dm's core to be included by itself and iOSShell.
Command line flags that are the same (or nearly the same) in DM
and in skia_tests have been moved to common_flags. Authors,
please check to see that the shared common flag is correct for
the tool.
For iOS, the 'tool_main' entry point has a wrapper to allow multiple
tools to be statically linked in the iOSShell.
Since SkCommandLineFlags::Parse can only be called once, these calls
are disabled in the IOS build.
Since the iOS app directory is dynamically assigned a name, use '@' to
select it. (This is the same convention chosen by the Mobile Harness
iOS file system utilities.)
Move the heart of dm.gyp into dm.gypi so that it can be included by
itself and iOSShell.gyp.
Add tools/flags/SkCommonFlags.* to define and declare common
command line flags.
Add support for dm to iOSShell.

Mike K: please sanity check Test.cpp and skia_test.cpp
Feel free to look at the rest, but I don't expect any in depth review of path ops innards.
Path Ops first iteration used QuickSort to order segments radiating from an intersection to compute the winding rule.
This revision uses a circular sort instead. Breaking out the circular sort into its own long-lived structure (SkOpAngle) allows doing less work and provides a home for caching additional sorting data.
The circle sort is more stable than the former sort, has a robust ordering and fewer exceptions. It finds unsortable ordering less often. It is less reliant on the initial curve tangent, using convex hulls instead whenever it can.
Additional debug validation makes sure that the computed structures are self-consistent. A new visualization tool helps verify that the angle ordering is correct.
The 70+M tests pass with this change on Windows, Mac, Linux 32 and Linux 64 in debug and release.

- refactor GYPs and a few flags
- make GPU tests grab a thread-local GrContextFactory when needed as we do in DM for GMs
- add a few more UI features to make DM more like tests
I believe this makes the program 'tests' obsolete.
It should be somewhat faster to run the two sets together than running the old binaries serially:
- serial: tests 20s (3m18s CPU), dm 21s (3m01s CPU)
- together: 27s (6m21s CPU)
Next up is to incorporate benches. I'm only planning there on a single-pass sanity check, so that won't obsolete the program 'bench' just yet.
