gdb/ChangeLog:
Update copyright year range in all GDB files
|

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

There are a few errors when trying to run the performance testsuite with
Python 3. This commit fixes them.
In Python 2, it was possible to use relative imports (importing a module
relative to the current one). In Python 3 it isn't. So I use
absolute_import from the __future__ module, which allows Python 2 to
behave like Python 3, and use the Python 3 syntax.
In Python 3, dict.iterkeys doesn't exist anymore. Using dict.keys is a
good compromise in this case.
gdb/testsuite/ChangeLog:
* gdb.perf/lib/perftest/perftest.py: Change relative imports to
absolute.
(SingleStatisticTestResult.report): Use dict.keys instead of
dict.iterkeys.

This patch adds a basic framework to do performance testing for GDB.
perftest.py is about the test case, testresult.py is about test
results, and how are they saved. reporter.py is about how results
are reported (in what format). measure.py is about measuring the
execution of tests by a collection of measurements.
In V5:
- Simplify perftest.exp.
In V4:
- Rename MeasurementCPUTime to MeasurementCpuTime,
- Add 'pass' in empty method,
- Simplify string comparison in perftest.exp.
- Rename GDB_PERFORMANCE to GDB_PERFTEST_MODE and rename
GDB_PERFORMANCE_TIMEOUT to GDB_PERFTEST_TIMEOUT.
In V3, there are some changes,
- Add wall time measurement, cpu time measurement and vmsize
measurement.
- Rename SingleStatisticTestCase to TestCaseWithBasicMeasurements,
which measures cpu time, wall time, and memory (vmsize).
- GDB_PERFORMANCE=run|compile|both to control the mode of perf
testing.
- New GDB_PERFORMANCE_TIMEOUT to specify the timeout.
- Split proc prepare to proc compile and startup.
- Disable GC while doing measurements.
In V2, there are several changes to address Doug and Sanimir's
comments.
- Add copyright header and docstring in perftest/__init__.py
- Remove config.py.
- Fix docstring format.
- Rename classes "SingleVariable" to "SingleStatistic".
- Don't extend gdb.Function in class TestCase. Add a new method run
to run the test case so that we can pass parameters to test.
- Allow to customize whether to warm up and to append test log.
- Move time measurement into test harness. Add a new class
Measurement for a specific measurement and a new class Measure to
measure them for a given test case.
- A new class ResultFactory to create instances of TestResult.
- New file lib/perftest.exp, which is to do some preparations and
cleanups to simplify each *.exp file.
- Skip compilation step if GDB_PERFORMANCE_SKIP_COMPILE is set.
