Commit following 6fc7f8fd.

column in TAP_SCHEMA. Such names are normalized (without any prefix and without
double quotes) when getADQLName() is called, but are returned just trimmed
by getRawName(). This latter is just used by TAPMetadata when writing the XML
description of all TAP tables.

[TAP] Add property to add/replace TAP resources & Add the tool function TAPConfiguration.newInstance(...).

[TAP] Add an XML TableSet parser. The main modification done in JDBCConnection is about the schema prefix of table when the DBMS does not support schemas: now, only standard tables are expected with the prefix 'TAP_SCHEMA_' and the upload tables also with 'TAP_UPLOAD_'.

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