Fixed lispworks serialization issues with floats & strings; fixed remove-derived-index bug that wouldn't properly delete

Fixes for Win32 allegro build; lispwork builds but fails to run; new test of :index class keyword which fails

Up and limping; 0.6.1 working HEAD is in good shape again.  Fails four tests (all cursor ranges).  Object ID's are turned off for now - they are a user configuration option

Remove all references to sleepycat; change to bdb db-bdb or
berkeley-db; passes all test for BDB and SQLite on Allegro/Mac OS/32-bit

Removed config.lisp and all Makefile related build options.  The build is
now entirely driven from the elephant.asd and ele-bdb.asd files with a
simple user customization file, config.sexp, that should be copied to
my-config.sexp and customized to the user's environment.  Thanks to
pinterface for the initial patch supporting this approach.  Foreign
library loading is also controlled from the asd files now at system
load time rather than at compile time.

FEATURE: Allow linux users to configure pthreads location in config.lisp
(NEEDS TESTING!)

Includes most SQL fixes - works under SBCL/ACL.  Two problems remain in indexing under SQL for both SBCL/ACL

allocation type...
