'result_'.

Additionally when an XML document is submitted in an HTTP POST request
(i.e. with the Content-Type = (text|application)/(.+-)?xml), this is
immediately set as a jobInfo in the created job.

This infinite loop occured only when the replacement object is just
a wrapping of the matching object ; after replacement, the new object was
inspected for matching objects.

Example: infinite loop if we want to wrap all foo(...) functions with
         the function ROUND in the following query:
    SELECT foo(foo(123)) FROM myTable
	     Expected result:
    SELECT ROUND(foo(ROUND(foo(123)))) FROM myTable
	     But generated result was:
    SELECT ROUND(ROUND(ROUND(......foo(foo(123))))) FROM myTable

See the test case TestDBChecker.testClauseADQLWithNameNull() for more details.

Now, it is recommended to throw a DBCancelledException from any DBConnection
long processing. It is already done for the upload of a table, the execution
of an ADQL query and the setting of a whole TAP_SCHEMA. The flag
JDBCConnection#cancelled has now a bit different meaning: it is set even if
the Statement.cancel() fails so that any JDBCConnection function can see that
a cancellation has been requested.

It was not possible to use a GROUP BY with a qualified column name.
So finally, now, a GROUP BY is a ClauseADQL<ADQLColumn> instead of
a ClauseADQL<ColumnReference>. Indeed, according to the ADQL's BNF,
GROUP BY items are only columns as they would appear in the SELECT
clause (i.e. qualified or not, delimited or not). On the other
hand an ORDER BY accepts ONLY column index or non-qualified column
name/alias.

The class ColumnReference is kept for backward compatibility (or in
case the next version of the ADQL grammar make items of GROUP BY and
ORDER BY of the same type: index or qualified column). Besides, this
class is still inherited for the ORDER BY clause items
(see adql.query.ADQLOrder).

a qualified column name should be allowed, but still no column index should be.

This error has been raised on the issue #32 by Zarquan.

- empty file
- not a valid VOTable document

In such cases, the following error message is returned:
  "The input file is not a valid VOTable document!"
A cause with more detais (especially the line and column numbers)
may be appended.

Cases handled with no error:

  - If the VOTable document has no rows, an empty table
    is uploaded. No error has to be returned.

  - If a row has a different number of columns than the number
    of declared FIELDs, additional values are ignored and missing
    values are replaced by NULL. This is actually nicely handled by
    STIL.

Two comments:

- JDBCConnection.getDBMSName(String url) is now deprecated ; it may disappear
  in a next version of the ADQLLibrary.
- In case the DBMS name can not be retrieved (generally because of an
  incomplete JDBC driver implementation), NULL will be returned.

Few useless casts have also been removed.

It is also now recommended to make DBConnection.executeQuery(ADQLQuery)
return NULL if the query has been aborted (indeed, the DBConnection is
the only one that can reliably know that fact). JDBCConnection has been
adapted consequently.
