Add support for getting parameters from new SBCL sbcl.mk.
Add support for getting parameters from CLISP makevars.
Add support for getting parameters for ECL and MKCL.

Refactor static linking to use the above.
On SBCL, this relies on the new feature :sb-linkable-runtime
(from 1.3.14-20-g402a8fab6).
On ECL and MKCL, have static-{image,program}-op be pass-through synonyms
for the usual variants.
Remove deceitful incomplete support for static linking on CMUCL.

Add shell test for static linking, to better work with SBCL (uses cl-launch).

Add class c-file for C files to compile, and o-file for precompiled objects.
They can be either dynamically loaded into the current process,
or statically linked into a new runtime.

Upgrade backward compatibility bundle from asdf 3.1.6 to 3.2.0.
Stop manually curating a minimal set of changes,
just adopt a new bundle.lisp wholesale.

Move the C toolchain support to its own system cffi-toolchain.

Create linkable object files and include them in output-files for
compile-op, so that they can be found and linked by a recent-enough
ASDF (3.1.6 or later).

Allow for delivery of a system with a single static and/or dynamic
library, and on support platform (CLISP, CMUCL, SBCL), enable delivery
of a standalone executable that statically links required extensions.

This requires a recent SBCL (will hopefully be released in 1.2.17).
ASDF 3.1.6 is required, but backward compatibility code is
provided at least back to ASDF 3.1.2.

On BSD, use ld -r for "libraries" instead of ar and possibly libtool.

When forking a Lisp to dump an image, support Quicklisp.

Make CFFI-Grovel generally more robust.

Document static linking operations in manual. Improve documentation.

Add test for ASDF support including wrappers.

The changes are summarized here:
http://article.gmane.org/gmane.lisp.cffi.devel/1029

Also adapted tests and examples and uffi-compat.

- Add UNPARSE generic function for unparsing types.
- Reverse the order of the type name and class in translator GFs.
- Add NEXT-* versions of the translator GFs.

- WITH-FOREIGN-OBJECT should eval the type parameter. Fixed this
  as well as the examples and tests that assumed it wasn't evaluated.
- document WITH-FOREIGN-OBJECT in the manual.
- removed the pseudo ability to specialize arguments on
  define-type-translator. That didn't quite work, doh.
- removed dead code from cffi-uffi-compat::foreign-type-size
  specialized on the uffi-array-type.
- uffi-compat: parse (:array <type>) as (:array <type> 1)
- uffi-compat: reflect the fact that CFFI:WITH-FOREIGN-OBJECT now
  evaluates the type parameter.

- Renamed: null-ptr -> null-pointer, null-ptr-p -> null-pointer,
  inc-ptr -> inc-pointer, with-foreign-ptr -> with-foreign-pointer,
  with-foreign-ptr-as-string -> with-foreign-pointer-as-string,
  foreign-slot-address -> foreign-slot-pointer,
  get-var-ptr -> get-var-pointer and
  foreign-symbol-ptr -> foreign-symbol-pointer.
- Updated various references to the old names in the cffi code itself,
  examples, tests and the manual.
- New functions: cffi(-sys):pointer-address and cffi(-sys):make-pointer.
- Use these in uffi-compat.
- Documented them in the manual.
- New tests: POINTER.1 and POINTER.2

- Use variables for the lisps' paths so that one can easily pick
  different versions to run the tests with. eg:
    CMUCL

- New tests: tests/enums.lisp (4 tests) and tests/misc-types.lisp (3 tests).
- New file: objects.lisp, skeleton of the safe typed pointer interface. I
  also added a :boolean type here, it's looking for a better home still.
- (early-types.lisp): type parsers, DEFINE-TYPE-SPEC-PARSER and PARSE-TYPE.
  Added abbility to have anonymous types (ie. a name is no longer required
  for FOREIGN-TYPE). Moved DEFCTYPE to types.lisp.
- (enum.lisp): improved DEFCENUM, the values for each keyword are now
  optional, like in C. Added the anonymous type (:enum ...)
- (types.lisp):
    - Renamed :TO-C-ARG to :TO-C-DYNAMIC.
    - Renamed FOREIGN-AREF to MEM-AREF and implemented compiler macros
      for it.
    - New exported macro: DEFINE-FOREIGN-TYPE for parameterized types.
    - Change DEFINE-TYPE-TRANSLATOR back to the previous interface,
      translators take a type argument now and we have translators
      available at runtime now too.
    - FOREIGN-TYPEDEF's now inherit their parent type's translators.
    - New :wrapper type, for anonymous typedefs with translators.
- (strings.lisp): Renamed string to :string. Added new type, :string+ptr.
- (utils.lisp): renamed let-if to bif.
- (tests/callbacks.lisp): two tests were not being run for SBCL
  because I thought it triggered a bug but it's actually only one that
  triggers the bug. Fixed that.
- Updated examples and tests to use :string instead of string.

Add unit testing framework using RT.
Lots of manual and CFFI-SYS updates.
Add passing a double float to sprintf in examples.lisp.
Update the syntax of the nested structure example.
Add the INC-PTR function to the CFFI-SYS backends.
Add the shareable byte vector interface to the CFFI-SYS backends.
Started writing support for aggregate structure slots.  Not used yet.

Add foreign enumerated types that automatically convert from keywords
to integers when passed or returned to/from foreign functions.

Clean up CLISP support some, will need CVS version of CLISP to properly
handle looking up symbols in all loaded foreign libraries.

Add preliminary support for CMU CL (tested in 19b-pre on OS X).
