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.)

Add JsonWriter, which handles Json output from DM, in preparation for
adding json output for tests. This change should not affect behavior.
