Switch from 'libx' to 'lib', delete all obsolete binaries

Because 'cd lib && mvn compile' can now download and (un)zip many
previously SCM-committed third-party dependencies, the following 'lib'
subdirectories have been deleted:
 - ant
 - asm
 - commons
 - jarjar
 - junit
 - regexp
 - saxon
This one is new (but not stored in SCM):
 - jdtcore-aj

For each of them, there now is a .gitignore entry, so as to prevent
developers from accidentally committing the downloaded binaries again.

+  <description>
+    This module downloads + installs libraries used by many tests, especially those running as Ant jobs. You should not
+    build this module during every build because it is somewhat slow, downloading stuff from 3rd-party websites,
+    unzipping some libraries (e.g. a full Ant distribution) and creating new ZIP files (e.g. source JARs, compound JARs
+    containing multiple libraries).
+
+    So just run 'mvn compile' once after cloning the AspectJ repository and you should be all set to subsequently build
+    AspectJ itself. If you forget this step, a Maven Enforcer rule in the AspectJ root POM will fail the build and
+    remind you to build this module.
+
+    Normally you never have to call 'mvn clean' here, but if for some reason the installed libraries are in an
+    inconsistent state (e.g. after an incomplete download), you can do so and then run 'mvn compile' again.
+
+    BTW, running 'mvn compile' multiple times will not repeat any download via Maven Dependency or Download Maven
+    plugins, but repeat all zip/unzip steps in TrueZIP Maven plugin. So try not to call it unnecessarily.

+            was made right from the lib/jdiff directory, using the following commands (without the line breaks):
+
+            mvn -Dfile=jdiff.jar -DrepositoryId=github -Durl=https://maven.pkg.github.com/kriegaex/aspectj-packages
