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

[UWS,TAP] Add clean release of all resources (e.g. Threads, Timers, DB connections) allocated in a UWS and a TAP service. Small changes of the UWS API...but only if ExecutionManager, DestructionManager and UWS have been implemented by library users rather than using the default implementation.

[UWS,TAP] Review some log messages (in the log file but also in the error summary of a job) ; particularly stack traces are added into the error summary, but are displayed just once in the logs.

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

[TAP] Fix bug in VOTable reading. The STIL consumer must be in a different thread. OnceRowPipe has been then replaced by a new internal static class re-doing the same work plus some adaptations, particularly to stop properly the stream reading before reaching the end of the VOTable.

[TAP,UWS] Addition to the last commit: the TAP resource /sync did not yet use the RequestParser to get its parameters, and so it did not worked as before the last commit.

[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.

[TAP] Deal with the DB type 'BOOLEAN' while uploading boolean values in the database => convert the boolean in a short value (1 or 0).

[ADQL] Keep the same order of columns as they are added inside the DBTable => use a LinkedHashMap rather than a HashMap

[TAP] Make TAP and UWSService use the same ServiceErrorWriter AND make DefaultTAPErrorWriter use the same VOTableFormat as the one declared as OutputFormat in the ServiceConnection.

[TAP] Fix a grave error: synchronous jobs were stopped much before the specified execution duration ; the library was waiting N milliseconds, where N is the TAP execution duration always expressed in seconds.

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

[UWS] Cancel last commit. The UWSException was thrown intentionnaly: if an error occurs while just creating the thread, this error should not impact the job ; it is an internal server error, not an error due to the job execution or of a wrong parameter. This error MUST be thrown AND the job MUST stay PENDING (so that it can be restarted later when the server bug will be fixed). Job parameters checks MUST be done either in the job execution (JobThread.jobWork()) or at the job creation (using an InputParamController).

[ADQL,TAP] Add geometry format in output and correct upload of STC-S regions. Geometrical type conversion from and into a DB type is now required in all JDBCTranslator. This allows formatting of geometrical column value coming from the database, but also the translation of STC-S expressions provided in uploaded table into geometrical column values.

[ADQL] Support the special escaping syntax for string literals in Postgres (strings to escape must be prefixed by a E before the starting ').

[TAP] Do not write optional XML attributes in the /tables when their value is NULL or an empty string.

[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] End of 'Fix synchronization bug while generating the default Job ID' (commit e6a9d52f)

[UWS] Correct the way the URL interpreter is used: at initilization with a HttpServletRequest, the full URL until the base URI should be saved + In UWSService, the used URL interpreter was a class attribute, which is a bad thing (this object is shared by several threads).

[TAP] Log format reports and end of ADQLExecutor execution, add an OVERFLOW notification for the text/plain output and check by default that the given service connection is not null in constructor.

[TAP] Adapt the MIME type of VOTable output in function of the chosen data part serialization AND let setting the VOTable MIME type after creation (useful only when no known serialization is chosen).

[UWS] Make XML representation of jobs and joblists valid (with their XML schema), and particularly the nodes jobs, job and the error type (which should be written in lower-case).
