timing.core: add ArrayListStore implementing ISegmentStore

This store is made for a corner case where we want a slightly more
memory efficient datastore.

This is used by the timing analysis to save a bit of memory at the
expense of intersection times.

This partially addresses bug 489217

segStore: Add a close method to ISegmentStore

This method will close the segment store backend at the end of the analysis or

This method will be useful when there is multiple segment store backends, so
that each one can take care of its own saving actions and cleanup.

lttng: Add configuration files to call LTTng-Analyses scripts

This patch implements configuration files to offer calling
LTTng-Analyses scripts [1] from Trace Compass.

The `index.properties` file contains a single property, `analyses`,
which is a whitespace-separated list of names of configuration files,
without the extension, to load in order to create as many LAMI
analyses.

Each configuration file contains two properties:

  * `name`: Display name of the analysis.
  * `command`: Full command to run. This string supports
    double-quoted arguments to allow arguments with whitespaces,
    or empty arguments. The `\` and `"` characters must be
    escaped with `\`.

Both properties are mandatory.

LTTng-Analyses 0.4 is supported, however 0.5 and up are recommended
since these will offer a proper progress bar and cancellation
mechanism.

analysis.lami: Implementation of LAMI plugins

If pre-defined scripts are present on the user's system (and on the
$PATH), options under the "External Analyses" trace sub-tree element
become available. Right-clicking on those allows running the specified
analysis, and will import the results as Reports in Trace Compass.

Reports are opened automatically when created, and will initially
display a table of the results returned by the external analysis.
The toolbar menu can then be used to generate charts from this data,
either Histograms or XY scatter plots.

Clicking on chart elemnents highlights the corresponding column in the
table, and vice versa. Also, if the data table rows contain a time
range or timestamp, integration via standard time selection signal
is done.

To not commit to final APIs yet, we've used the "internal.provisional"
naming, as described in [1].

Full user documentation and additional unit tests will follow.

Current limitations:
- The RunAnalysisHandler and others are specific to LAMI analyses,
  which means other types of OnDemandAnalyses would have to define
  their own way of being started (which may not even be through
  a right-click menu option).

tmf: Fix the actual end time of state system modules

State providers keep track of the latest event that was handled is returns
this time as the current end time.

State system analysis module use this time to determine if an analysis is ready
to be queried. Also on the way to fix bug 488757.

tmf: Introduce dependency level for event requests

Requests with the same dependency level that are compatible otherwise
can be serviced by the event provider together. In TMF, the
TmfEventProvider will coalesce these requests together to a coalesced
event request so the trace is read once and the events are dispatched
to each sub-request.

If these request are not on the same dependency level, then each
request will be serviced separately by the event provider.

This can be useful, when a request has to wait for a condition to
happen in another event request. It can block its request till that
condition is met. If both request were coalesced the coalesced request
will deadlock by one request.

Side effects of this patch:
- Traces (TmfTrace) will be read concurrently when using different
dependency levels. The event request scheduler of the TmfEventProvider
will take care of scheduling each request.
- In an experiment, requests may not be serviced by the same
TmfEventProvider, some may be serviced by the TmfExperiment, some
by the children traces (TmfTrace).

tmf: Introduce base class and extension point for on-demand analyses

The on-demand analyses are analyses that are run manually when
the user requests it. As such, they are much more simple and
much less featureful than regular analyses.

The upcoming integration with the LTTng-Analyses scripts will
make use of this.

ss: make node cache static

The state system is being used in many places now. A kernel trace
can have over 10 state systems running simultaneously. Therefore,
the caches have been taking more and more space. A summary reading
of heap dumps showed that for a kernel trace now, 512 mb is needed
for these caches. This will not scale.

This patch makes ONE cache for all of trace compass. There is a tiny
heuristic, each location is offsetted by the object's hashcode. This
is to avoid too much cache thrashing du to temporal co-locality.

The seek times in trace compass (going from one place to another)
are accelerated by a factor of 3 and are noticeable on an i7 with
16gb of ram and an ssd.

Moreover, this patch improves scalability, by making trace compass
not run out of memory after opening 5 kernel traces simultaneously.

lttng.ust: Tweaks to BinaryCallsite

- Rename the aspect (and Event table column) to Binary Location.
- Remove the concept of function name, it is not part of the
  information available from the trace. Was not being used
  anyway.
- Print the offset differently depending on if the address is
  absolute or not:
  /usr/lib/mylib.so+0x123 for Position-Indpendant-Code (PIC) binaries
  /usr/myprog@0x401234 for non-PIC binaries

The differentiation PIC/PIE is not very robust at the moment
(we just check if the file name ends in ".so"), but it will be
improved due to a new field being added by UST soon.

tmf: Introduce "External Analyses" and "Reports" project elements

These will contain the upcoming LTTng-Analyses wrappers, along
with the reports they will produce.

"External Analyses" will be refered to as "on-demand analyses" in
the code, as this is what this sub-tree will eventually become.
We can use this name for now to better differentiate with the
"standard" analyses, which are still shown in the Project View.
