[TAP] Fix bug in upload (uploaded tables were given twice to the db checker) & Allow customization of the DB upload schema in the tap factory

[TAP,UWS] Fix a problem with the format of the error details returned by the parameter .../error/details. In TAP a VOTable document is expected, but a text/plain description was returned (default behavior in the UWS lib.). Now, a ServiceErrorWriter is used to format the error details correctly.

[TAP] Fix MAXREC bug (maxrec was ignored if = 0) & Replace the MIME type for VOTable output from 'text/xml' to 'application/xml'

[TAP,UWS] Small log corrections (for Thread logs, display the thread name rather than the ID ; the job id was forgotten in the log of CHANGE_PHASE ; build a UWSException with the given throwable message as message ; in log TAP for the event EXECUTING, the memory address of the ADQLQuery object was displayed rather than of the ADQL query expression ; display the stack trace of the SQLException.getNextException() when calling logDB)

[TAP,UWS] Manage thrown Error properly in synchronous and asynchronous jobs execution + Modify some log messages + Add log messages in JDBCConnection (for add and drop uploaded tables).

[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] Remake TAPFactory into an abstract class + let limit the number of jobs (async and sync) by allowing the TAPFactory to communicate with a connection pool

[TAP] Come back on the v1.0 definition of TAPLog and fix a bug (missing DB table name in logs for CREATE, INSERT, DROP TABLE ; name missing in getFullDBName(TAPTable))

[TAP] Fix the /tables output: the UCD node was after UType...it should be just before (warning raised by TAPLint)

[TAP,ADQL] Improve and remake a part of the database connection. Missing javadoc has been added when missing in the modified tables.

[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

  - 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).

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.
