Add unix-domain socket support for Allegro CL (tested with Express
edition for Linux/x86).

Put the PG defsystem in its own package.

Load sb-rotate-byte from the ASD file.

Modified sbcl unicode support, works for me.
Moved requires into asdf package, otherwise we get asdf package problems, unknown if it works with other lisps

Update to a more recent version of md5.lisp, taken from SBCL's SB-MD5
contrib. The change is motivated by the fact that SBCL generates a runtime
error "function declared not to return returned" with the current
code. Made a few changes to make the code compile in other Common Lisp
implementations.

add a file that does a manual load of pg

- add md5 authentication (thanks to Brian Mastenbrook). Uses Pierre Mai's
    portable md5.lisp library, that has been added to the project (with extra
    EVAL-WHENness to please OpenMCL and ACL).

    Tested with CMUCL, SBCL, OpenMCL, CLISP, ACL 6.1. ABCL does not compile
    md5.lisp, probably for more EVAL-WHEN reasons. Only tested with PostgreSQL
    version 7.4.

More factorization of lowlevel functions between v2 and v3 protocols.

Integrate Peter Van Eynde's v3 protocol support:

   - create PGCON-V2 and PGCON-V3 classes
   - PG-CONNECT attempts to connect using v3 protocol, and falls back
     to v2 protocol for older backends; return a PGCON-V2 or PGCON-V3
     object
   - PG-EXEC and FN and PG-DISCONNECT are generic functions that
     dispatch on the connection type
   - protocol code split into v2-protocol.lisp and v3-protocol.lisp

TBD: cleaning up the notification & error reporting support, and
factorizing more code between the two protocol versions.

Also split code out into multiple files:

   - large-object support
   - metainformation about databases
   - parsing and type coercion support
   - utility functions and macros
