tmf: bug 495897 Keep last good formula on failed synchronization

When trace synchronization fails, the last known good formula should be kept
and the traces synchronized. It is a better approximation than to keep the

tmf: Fix intermittent failure in ProjectExplorerTraceActionsTest

To reproduce the issue:

In TmfTraceElement.delete, add a Thread.sleep(5000); right after the
syncExec that calls closeEditors.

Run ProjectExplorerTraceActionsTest.test4_05Delete then
test4_09BringToTop (you can create a new test method and call them in
that order).

The problem is that the delete test waits until the delete dialog and
the editor are closed but there is no guarantee that the file will
actually be deleted right away. While the file is still there, it is
possible that the next test will start and begin the process of
opening the same existing trace. But then the file gets deleted and
the trace doesn't validate properly (or other exceptions depending on
the timing of when the trace gets deleted).

We should make sure that the file is deleted before proceeding.

lttng.ust: Improve debug-info binary tracking

This patch improves the tracking of binary loading/unloading using the
LTTng statedump and dl events.

It changes the layout of the attributes in the state system to be this:

  Key                      Value
  /vpid                    -
  /vpid/<baddr>            <active>, 1 if active, null otherwise
  /vpid/<baddr>/build_id   <buildid>, e.g. "0123456789abcdef"
  /vpid/<baddr>/debug_link <debug_link>, e.g. "/usr/lib/libhello.so.debug"
  /vpid/<baddr>/memsz      <memsz>, e.g. 2127280
  /vpid/<baddr>/path       <path>, e.g. "/usr/lib/libhello.so"
  /vpid/<baddr>/is_pic     <is_pic>, 1 or 0

which is organized a bit more logically than the current approach.

Currently, the code expects the binaries to have a build id.  If this is
not the case for a particular binary, it will stay forever in the map of
pending binaries.  This patch checks the has_build_id to know whether or
not we should wait for such a corresponding build_id event.  While at
it, we do the same for debug link and propagate its value (although
nothing useful is done with it currently).

The "statedump start" event is now handled, which is required to
invalidate all the mappings for a certain vpid.

More tests are added, using the new synthetically generated traces from
CtfTestTrace.

of a certain type. The common pattern to handle an event field
would be:

- field = content.getField()

- make sure value is not null and of the expected type

Doing this every time we want to read a field is very
cumbersome, we can add a getFieldValue() utility method to
directly get the value into the expected type. So then we
just need to:

- content.getFieldValue(expectedType, fieldName);
- null-check the result

ss: Relax but enforce the character limit in HTInterval strings

The string parsing logic in HTInterval casts the string length to
a byte, which can result in a negative value (and subsequent
NegativeArraySize exception) if the string is actually > 127 bytes
in its encoded form.

A comment mentions that the string length is checked at the
constructor, but this is false! No check is done whatsoever.
The limit should be checked.

While at it, the current limit of 127 bytes is very small for
string values. File system paths for example can easily add up
to more than 127 characters. For this reason, use a short (2 bytes)
instead of one byte to store the string length, which allows for
strings up to 32,767 bytes.

Finally, specify UTF-8 encoding explicitely. This is what was
happening on most platforms already, but it's a better practice
to specify it, and it makes static analysis happy.

common: Add JUL logging to TraceCompass

Logging allows to add tracepoints at various places in the code, and at runtime
enable log handlers for specific components to produce log files that can then
be analyzed by various tools... like Trace Compass!

This patch is a first suggestion for adding logging facility to TraceCompass.
Here is the suggested approach:

* Logging has a small overhead, so they should have a negligible performance
impact performance if they are not overly used.

* Logging must be explicitly enabled at runtime by setting a parameter to true:
-Dorg.eclipse.tracecompass.logging=true in the vmargs

* Each class should have their own logger, using the class's full name
(canonical name). It is thus easy to filter which classes to log using per
logger name. For example, logging org.eclipse.tracecompass.tmf will log all
loggers that start with o.e.t.tmf.*

* Abstract classes should use their concrete class's name, to match the log
statements to their concrete component.

* The TraceCompassLog class contains a wrapper methods to retrieve loggers.
Calling it makes sure that the main logger's level has been set and the default
values set by java (info level with ConsoleLogger) are not used.

* What is non-negligible in logging is often the message being logged. To be
meaningful, the message will often add parameters concatenated to a string
and that can be very costly. Messages should be lazily constructed using
the logging statements taking Supplier<String> in parameter. For example:

LOGGER.log(() -> "My msg " + param1 + " " + param2);

* Log levels, handlers, etc can be controlled via a configuration file set in
the vmargs: -Djava.util.logging.config.file=/path/to/logger.properties. An
example logger.properties file can be found here:
https://wiki.eclipse.org/Swordfish_Documentation:_Turning_On_Logging

* To help logging trace parsing, the log strings should have the following
format: [EventName:MayContainSemiColon] paramName1=param1, paramName2=param2
