RepositoryTestCase.fsTick() was was waiting 64, 128, 256, ... milliseconds
until it detected that the filesystem timer has ticked. Make use of
the filesystemtimer resolution information in FS to sleep a fraction
of the filesystem timer resolution. That raises probability to wake up
shortly after the filesystem timer has ticked.

FileSnapshot.notRacyClean() assumed a worst case filesystem timestamp
resolution of 2.5 sec (FAT has a resolution of 2 sec). Instead measure
timestamp resolution to avoid unnecessary IO caused by false positives
in detecting the racy git problem caused by finite filesystem timestamp
resolution [1].
Cache the measured resolution per FileStore since timestamp resolution
depends on the respective filesystem type. If timestamp resolution
cannot be measured or fails due to an exception fallback to the worst
case FAT timestamp resolution and avoid caching this value.
Add a 10% safety margin in FileSnapshot.notRacyClean(), though running
FsTest.testFsTimestampResolution() 1000 times which is not using a
safety margin didn't fail on Mac using APFS and Java 8, 11, 12.
Measured Java file timestamp resolution: [2]

Replace simple uses of Iterator with a corresponding for-loop.
Also add missing braces on loops as necessary.

Use of String.equals("") can be replaced with with String.length() == 0
(for JDK5 and lower) or String.isEmpty() (for JDK6 and higher)

Several of the utility methods create a Repository without setting
the 'autoClose' flag, which means that the caller is responsible for
closing it. Update the Javadoc to explicitly mention this.

Since 8ed59c5 ("Make TestRepository AutoCloseable", Jan 11, 2019) the
TestRepository class is auto-closeable, but instantiations of it were
not converted to use try-with-resource.
Converting to try-with-resource results, in several cases, in the
repository being closed twice because LocalDiskRepositoryTestCase has
logic to close created repositories in the tearDown method. This results
in several tests emitting a warning to the console:
close() called when useCnt is already zero
Change the default behavior of the createRepository method to not use
the auto-close logic in LocalDiskRepositoryTestCase, so that thy will
instead be closed (only once) using the AutoCloseable implementation.
Deprecate the method that has the autoClose parameter.

Currently, unit tests need to either close the Repository underlying a
TestRepository manually, or not close it at all. Both are error prone.
The TestRepository holds a reference to 4 AutoCloseable objects:
Repository, ObjectInserter, Git, and RevWalk. The last two can escape
the TestRepository scope, so they are not closed when TestRepository is
closed.
