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.

The function #'expand-to-foreign-dyn-indirect, used by cffi-libffi, did
not create the correct expansion when there was an enumerated argument,
because two translations are required, one from the symbol to an
integer, and the second to make the integer indirect, passing a pointer
to libffi. This remedies that problem by defining a method for
expand-to-foreign-dyn-indirect specific to foreign-enum that recursively
calls expand-to-foreign-dyn-indirect twice. A test, fsbv.8, has been
created.

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.

Tests fsbv.1 and fsbv.2 added that test foreign structure call and
return by value.  This includes the C file and addition to makefile to
generate the appropriate library, libfsbv.  So that the tests are
properly defined, load cffi-fsbv and then cffi-tests.  Both tests
should pass.  The test returning a structure, fsbv.2, exposed an error
in the form generated by ffcall-body-libffi; because it always
generated a mem-aref on the return value, the subsequent
translate-from-foreign was effectively making a double translation.
Thus, this form generation has been conditionalized so that if
translate-from-foreign will not be applied (e.g., built-in-type) to
call mem-aref, otherwise just return the pointer.

As of OSX 10.6.6, loading things like CoreFoundation on something
other than the initial thread results in a crash.

Implemented workaround on SBCL based on what CCL does upstream. Other
Lisps might benefit from similar workarounds.

- Using #-windows instead of #-(or win32 mswindows) which didn't work
  on Clozure CL.

Suggestion and initial patch courtesy of Josh Elsasser.

- Preliminary (likely buggy) version.  Includes documentation and tests.
- New cffi-features: big-endian and little-endian determined with CFFI
  code.
- Needs cleaning up.

- cffi-tests.asd: use gmake on solaris too.
- new cffi-features: sparc[64] and hppa[64], SCL-only.
  (updated the respective test)
- libraries.lisp: handle ERROR instead of SIMPLE-ERROR.
- tests/bindings.lisp: bugfix?

Patch courtesy of Douglas Crosher.

- Make the test-suite run both with and without rt::*compile-tests*
  bound to T.

- Make defcfun.undefined an expected failure for SBCL on
  non linkage-table platforms.
- New file: tests/misc.lisp.
- Added a couple of tests for cffi-features.

- Makefile: new test-scl target. Add SCL's fasl file extensions
  to the clean target.
- Remove SCL TODO item.
- New file: cffi-scl.lisp.
- New primitive type :long-double. Since it's only supported by
  SCL, it's not worth adding a no-long-double feature just yet.
- New tests for :long-double.
- Add information about SCL and the new :long-double type to
  the user manual.

- Updated cffi-ecl.lisp, courtesy of Michael Goffioul.
  (Includes some ECL specific workarounds in the portable
   bits of CFFI.)

- 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.

- Move #-cffi/no-foreign-funcall from cffi-tests.asd to
  tests/funcall.lisp and have the lisps that don't support this
  push the feature in cffi-<lisp>.lisp instead of defpackage.
- New file: utils.lisp
- Make Allegro, CMUCL, Corman and OpenMCL use callback-symbol-name  (from cffi-utils) to safely intern callback symbol names (James)
- Clisp: consider (pointerp NIL)

- New interface: DEFCALLBACK, CALLBACK, GET-CALLBACK
- New CALLBACK.* tests.
- Implementations of CFFI-SYS:MAKE-CALLBACK:
    - Allegro, passes all tests on linux/x86 and win32
      fails CALLBACKS.CHAR/UNSIGNED-CHAR/SHORT/UNSIGNED-SHORT
      on darwin/ppc, looks like an Allegro bug.
    - clisp, passes all tests.
    - cmucl, passes all tests on linux/x86, on darwin/ppc fails
      CALLBACKS.CHAR/UNSIGNED-CHAR/SHORT/UNSIGNED-SHORT, looks
      like a bug in cmucl/ppc too.
    - sbcl, x86 only, passes all tests except its callbacks
      can't handle sap's yet, that'd be bug in sbcl too.
    - openmcl, fails CALLBACKS.FLOAT/DOUBLE, I reported this
      bug in openmcl, and it has been confirmed.
    - Lispworks, passes all tests on darwin/ppc, on linux/x86
      and win32 there are issues unrelated to callbacks.

* Push :cffi/no-foreign-funcall to *features* when the host
  lisp does not support it.
* Don't run the funcall tests when #+cffi/no-foreign-funcall
* Unexport foreign-var-ptr, it's meant to be used by defcvar
  only.
