I didn't get any significant feedback from the earlier draft so here's
the finished 'feature patch 1' for plperl. (This builds on my earlier
plperl refactoring patch, and the follow-on ppport.h patch.)

Significant changes from the first draft:
- New GUC plperl.on_perl_init='...perl...' for admin use.
- New GUC plperl.on_trusted_init='...perl...' for plperl user use.
- New GUC plperl.on_untrusted_init='...perl...' for plperlu user use.
- END blocks now run at backend exit (fixes bug #5066).
- Stored procedure subs are now given names ($name__$oid).
- More error checking and reporting.
- Warnings no longer have an extra newline in the NOTICE text.
- Various minor optimizations like pre-growing data structures.

Additional changes from the second draft:
- SPI functions aren't available during plperl.on_*_init execution.
- Added utility functions: quote_literal, quote_nullable, quote_ident,
encode_bytea, decode_bytea, looks_like_number,
encode_array_literal, encode_array_constructor.
- Enabled plperl to "use"/"require" safely by redirecting the require
opcode to code that dies if module not already loaded.
- Corresponding changes to the documentation.

Additional changes in this version:
- Added the missing ', arguments' to docs of spi_exec_prepared().
- Added Util.c to list of files for plperl make clean to delete.

I'll add this to the commitfest.
