This commit reverts commit 89418d13.

The reverted commit will be applied in another branch (probably 'adql-2.1') as
it is part of the next release of ADQL-Lib.

- Now, `ADQLParserFactory.createParser(...)` should be used to create a parser
- Only the new function `LOWER` is supported for the moment
- Not yet possible to manage the optional features _(next dev to come)_
=> 1st step for ADQL-Lib v2.0

- TAP adapted so that using the last stable version of the ADQL language
  (i.e. 2.0 for the moment)
  - but not yet possible to set the ADQL version to use in the configuration
    file

Before, the scripts relied unfortunately on the compilation performed by
Eclipse. Now, all the JUnit test cases are compiled all the time before
performing the JUnit validation (i.e. ANT task named `junitValidation`).

This is very useful when getting a stack trace of an exception: without
this option, no method and line information can be provided...so, without
this option, the stack trace becomes pretty useless.
(NOTE: this option increases a little the size of the compiled classes)

You can now set the adql.bootclasspath system property to use
an alternative bootclasspath, for instance that for a different
JRE than that used by the compiler.

For instance, this cross-compiles to java 1.5:

   ant -Dant.build.javac.target=1.5
       -Dadql.bootclasspath=/usr/java/jdk1.5.0_22/jre/lib/rt.jar
       -f buildADQL.xml
       buildLib

Note the java used by ant has to be at least java 6 because of the
@Override source constructs on methods inherited from interfaces
(only methods from abstract or non-abstract classes can be annotated
with @Override in java 5).

[TAP] Upgrade STIL version + Specify charset encoding for Javadoc generation in all Ant build scripts.

[ALL] Update ANT build scripts to test all existings JUnit tests before compiling. In case of error, the compilation does not complete.

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

TAP: Execute all JUnit tests before building the TAP library. At any JUnit failure, the build is canceled
+ Update the version number for the generated JARs.
