In the UWS and TAP configuration files the executionDuration has to be
provided into milliseconds. But the UWS parameter MUST be in seconds.
So now, UWS is still keeping this duration in seconds (in its
ExecutionDurationController) but TAP keeps it in milliseconds (in order
to avoid unexpected silent modification of the API) and converts it into
seconds for its controller (i.e. TAPExecutionDurationController), for the
default home page and for the Capabilities page.

[UWS,TAP] Errors and log management improvements. Particularly, now TAP and UWS are able to manage correctly HTTP request abortions (i.e. when the user stop the request before the response has been fully sent, or when there is a connection problem or a time-out). Such abortions are considered by UWS and TAP merely as job abortion/cancel. No error is logged any more. In addition of this correction, log entries concerning the execution of a TAP sync/async job have been modified so that having more coherents messages. And stack traces of exception that occurred when executing a job (sync or async, tap or uws) are displayed just once: at the JOB END log entry, and not by the HTTP RESPONSE_SENT entry. And finally, output flush and interruption detection are made more often when writing a query result (the flush is particularly important when combining with fetch-size > 0 in synchronous mode....the sync response is then a streaming output).

[TAP] Change the default value for output and upload limits ; only negative value must mean 'no restriction' ; 0 must be a normal allowed value.

[UWS,TAP] Fix UPLOAD bug (the last line of the table to upload was ignored). Fix an improbable NullPointerException in the MultipartParser.

[TAP] Fix bug with the UPLOAD parameter: on any job parameter modification (with a 2nd http request), the UPLOAD parameter was deleted

[UWS,TAP] 3 MAJOR DEPENDENT FIX: improve significantly the parameters extraction from HTTP request in UWS (1) AND move the file-upload ability into the UWS library (2) AND the modification of parameters in UWS is now conform with the standard (3). (1) Only application/x-form-urlencoded content-type was supported. However a UWS must accept a request body containing only an XML document as a single byReference parameter. It is now done when the content-type is not known. (2) Besides multipart/form-data is now fully supported in UWS and so is still possible in TAP. (3) In the UWS standard, parameters can not be added after creation: they can just be modified. This rule is now respected in the UWS library.

[UWS,TAP] Review the standard parameters checking. Particularly, because before, the default value was never used while no value was specified by the user.

[ADQL,TAP] Add STC-S and UDFs support in the ADQL parser. Now, it is possible to provide a list of allowed UDFs, regions and coordinate systems. The ServiceConnection of TAP is now able to provide these lists and to propagate them to the ADQLExecutor. UDFs and allowed regions are now listed automatically in the /capabilities resource of TAP. The type 'geometry' is now fully supported in ADQL. That's why the new function 'isGeometry()' has been added to all ADQLOperand extensions. Now the DBChecker is also able to check roughly types of columns and UDFs (unknown when parsing syntactically a query). The syntax of STC-S regions (expressed in the REGION function) are now checked by DBChecker. However, for the moment, geometries are not serialized in STC-S in the output....but it should be possible in some way in the next commit(s).

[UWS,TAP] Fix timestamp format. Now, each returned date will expressed in UTC and using the ISO8601 format. Any given date is also expected in UTC (or with a time zone offset) and in ISO8601Format. These rules apply also for uploaded tables and for timestamp columns in a query result.

[TAP,UWS] Make valid VOTable results and errors. Some error messages about expected TAP request parameters have been changed.

[UWS,TAP] Review the exceptions and logs management + Add log file rotation (with a configurable rotation frequency)

[TAP] Check ADQLExecutor behavior + Review/Add/Complete Javadoc in all classes of this commit except AsyncThread and TAPParameters + Remake the upload management

[TAP] Remove all generic types + Delete specific (for ResultSet) output formatters + Modify the main output formatter

  - no provided value => default value
  - no default value => max value
  - no max value => no limit
  - default value must be <= max value
  - user value must be <= max value
