package into the top-level package, where it should be. Dependent classes updated
to reflect this move.

- Moved CodeMerger and TLVInserter classes to ch.usi.dag.disl package, because DiSL class is the sole user.
- Removed the utilinstr.* packages to reduce package clutter.

- Document the need for binary names in DiSL-Classes attribute

can recognize DiSL classes by the presence of other snippet-related 
annotations.

- Updated dislintro.tex to mention that the DiSL-Classes manifest
  attribute requires a comma-separate list of fully qualified class names.

- Modified builds system to automatically find DiSL classes in test suites.
- Removed MANIFEST.MF files from test suites.
- Changed class name separator for DiSL-Classes attribute from colon to comma,
  because the Ant "jar" task does not like the colon as a separator when generating
  MANIFEST.MF on the fly.

- Added an Ant task to create a formatted dump of binary file.
- The Ant build system now generates the files needed by the native agents.
- The DiSL agent build system now expects bytecode.c to be present.

- Removed refenreces to ASM library in examples.

- Shadow VM agent now uses the bundled JNI and JVMTI include files.
- Ant build system adjusted to the new Makefile.

- DiSL agent Makefile: compose library names for all platforms.
- DiSL agent Makefile: use -fwhole-program only with Linux and Windows targets.

build.xml: don't use the whole-program build for the MinGW version of disl-agent.

- Made compilation of LaTeX documentation conditional.
- Documentation is built only for a binary release (requires pdflatex). 

- Removed the old DiSL agent code as well as the old Java agent.
- Copied old shared DiSL agent headers to Shadow VM agent.
- Added JDK includes for JNI and JVMTI to avoid looking for them.
- Unified the naming of source directories.
- Updated the test infrastructure to the new build system layout.
- Examples can be now run even from the source distribution.

- The build.xml file has been cleaned up extensively.
- The build system for examples has been simplified and cleaned up.
- There is support for binary DiSL releases with examples and documentation.
- Examples should be used with a binary DiSL distribution (see output/dist).
- Moved the disl.py launcher out of the examples subdirectory.
- Test suite Runner has been modified to accept locations and native library names from outside.

Runner.java: Join strings instead of constructing File instances just to convert them to String in the end.

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.
