[TAP] Replace Savot by STIL + Change datatype management in TAPColumn (vot-type is no more available from here), TAPType (no votable type inside it) and VotType (can now be created from a TAPType instance + a VotType instance can be converted easily in a TAPType object)

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

[TAP] Improve TableIterator + Adapt ResultSetTableIterator (particularly because of the last commit about TAPType and VotType) + Add a TableIterator for VOTable input: VOTableIterator + Add its JUnit test case

[TAP] Remove TAPTypes and create a new class to represent a TAP column type: TAPType. + Improve the conversion between VOTable type and TAP type by embedding it in TAPType. + Modify TAPColumn in order to integrate TAPType and that its VotType is just a conversion of a TAPType. {This commit is not compilable.}

[TAP] Add the interface TableIterator (whose implementations let iterate over any kind of table data set) and its first implementation for ResultSet + JUnit test case

[TAP] Rename TAPMetadata.TableIterator into TAPMetadata.TAPTableIterator (it iterates only on the content of a TAPTable object and not on a data table. + Typos

Remove useless and blocking test (when url-pattern in web.xml is set to the root: /*) in the UWS URL parsing. + Add very basic check on its implementation

[UWS] Improve the test of an URL: it may be null or the interesting part of it can be ; the two cases must be tested.

[ADQL] Change the version number inside the ADQL library builder...next modifications will be for the version 1.3 or more.

ADQL: Provide the position of any column reference (column in ORDER and GROUP BY) when returning a ParseException

ADQL: Fix big bug: no parenthesis in the SQL translation for ADQL constraints with parenthesis ( ex: A AND (B OR C)) )

1/ let the function ROUND having 2 parameters
2/ wrap Operations (WrappedOperand) with brackets when there are brackets in the ADQL query

  - 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

Revert "TAP: Modify the xSV formats in order to let developer specify a MIME type and short MIME type (or alias) for any SV format, but especially for the one not already managed (CSV and TSV)."

This reverts commit 2379c606.

TAP: Modify the xSV formats in order to let developer specify a MIME type and short MIME type (or alias) for any SV format, but especially for the one not already managed (CSV and TSV).

ADQL: Correct version number for all modified ADQL related classes since the official v1.1 release. Now, version number after any modification in ADQL is v1.2.

ADQL: Fix an ADQL bug (raised by Dave Morris) in the management of subqueries: before, it was impossible to use (in a clause different from the FROM) columns of a father query inside a subquery.

Becareful with the function addMatch(ADQLObject, ADQLIterator): the iterator may be null if the match to add is the root search object itself!
No modification needed in SimpleReplaceHandler: Null test already done :-) !

TAP: Fix incorrect XML format: the INFO for PROVIDER was not ended properly => an error was raised by TOPCAT when a Java error was occuring in TAP or in a query execution.

ADQL: Completely change/improve Joins management, and particularly NATURAL JOIN and USING JOIN. Now, every joined columns are represented by a DBCommonColumn instance which has a given table coverage.
Before, there was a problem while using at least 3 or 4 NATURAL JOINs. Bug raised by Menelaos Perdikeas (ESAC).
