Revert r1643912 (Log4J Version 2 support for JULI).

Use of ant patch task is problematic on Windows.
Need for JULI integration needs more justification.
Check with upstream commonas logging.

Min default buffer size must be at least 8k so this is fine.

Revert original fix for BZ 57142 that attempted to:
- determine if the page might use EL
- if it did, create the ELContext (that would be required anyway) and set the
  necessary imports on the ImportHandler when the page loads

This alternative implementation:
- Generates a list of package and class imports at compilation time
- Which are then used when the ELContext is created

The main advantage of this approach is that the ELContext is only generated if it is definitely going to be used rather than if it might be used. There are also some minor optimisations regarding the timing of the String processing to differentiate between package and class imports.

Don't return the uri if things go wrong. Given that the error states in question should never happen, throw an ISE instead.
