EMMA 2.0.4217 released

Release 2.0.4217 contains bug fixes and various low-hanging fruit
improvements. The codebase is being moved closer to being a better starting
point for the future 2.1 branch.

FEATURE REQUESTS IMPLEMENTED:

975695 silent mode for data collection
979973 logging infrastructure enhancements

There have been several requests for a feature to silence logging in
EMMA-instrumented classes (used by builds that validate stdout output). This
has been implemented. Additionally, log output from EMMA runtime used to
omit "EMMA:" prefix. This has been corrected and can be used for
simple grep filtering of EMMA output as well.

The documentation has been updated to reflected new verbosity-related
properties, but briefly you can use several mechanism to control EMMA
verbosity:

(1) a JVM system property:
java -Demma.verbosity.level={silent,quiet,info,verbose}

(2) property "verbosity.level" set in a classpath resource "emma.properties"
or in a file pointed to by -Demma.properties JVM system setting

(3) for EMMA ANT tasks you can (additionally) set verbosity via a new task
attribute "verbosity" of <emma>, <emmarun>, <instr>,
<report>, <merge>. Note that different subtasks can have their
verbosities set to different level.

In other words, the new property follows the usual EMMA property inheritance
mechanism.

988785 improve instr output dir validation

To prevent users from mistakenly asking EMMA to output intrumented classes
in a directory that appears in the input path, the instr tool will now
validate that the output dir does not have one of the input dirs as its
parent.

DEFECTS FIXED:

988160 Negative number displayed in report for line %

The fix removes an int multiplication overflow when a coverage report is
generated for a very large codebase (thousands of classes).

989071 incremental instrumentation disabled for jar input

Unnoticed until now, the instr tool used incorrectly formed output file
descriptors when detecting whether instrumented classes were more recent than
the source files. As a result, the output classes were always
regenerated (this happened for jar inputs only).
