src-test: Added support for test debugging -- jobs can now output their command line with -Ddisl.test.debug=true.

ClientServerEvaluationRunner: check shadow's standard and error outputs, not the client's in assertRestOutErrNull().

Files: removed, as it actually only served for string utilities.
Duration: added await() and awaitUninterruptibly() methods.
Duration: softSleep() -> sleepUninterruptibly() for consistency.
Duration: timedWait(), timedJoin() -> wait(), join() since the time is implicit.
Duration: moved to the ch.usi.dag.util package in src-util.
Job: remove duplicated __streamToString() and use Strings.drainStream() instead.
Job: use the generic awaitUninterruptibly() in waitFor().
src-test: reflect the above method and class movement.

WeavingCode: added support for DynamicContext methods to read static and instance field values.
WeavingCode: cleaned up the weaver to highlight opportunities for refactorization.
src-test: added a test suite for the new DynamicContext methods.

src-test: moved various methods into classes in src-util and updated the test util classes accordingly.
build.xml, build.properties, .classpath: added support fo the src-util directory.

FieldAccessStaticContext: made the class public instead of package private, so that it can be actually used.

ClientServerRunner, ClientServerEvaluationRunner: pass also "disl." properties to the instrumentation server.

ProcInstance: getApplyType()->getMode() which is consistent with the returned type.
WeavingCode: reflect the changes prior to merge of new WeavingCode.

DynamicContextException: renamed to InvalidContextUsageException to better fit its usage.
DiSL, Weaver, WeavingCode: updated to reflect the change.

AsmHelper: various changes needed for WeavingCode to be merged
