It remains compatible with existing code, but accepts additional formats for bindings:
1) (name slot-name) - just like WITH-SLOTS;
2) (name :pointer slot-name) - a pointer version.

This includes size, ssize, ptrdiff, offset, intptr, and uintptr

* add option :CANARY to DEFINE-FOREIGN-LIBRARY: a foreign symbol unique
to the library

If that symbol is found in the current image before
the first attempt to load the library, the latter is assumed to be
statically linked and LOAD-FOREIGN-LIBRARY only marks the load state
as :STATIC before returning.

* add new slot LOAD-STATE which, together with HANDLE, tracks the
library

| library state     | LOAD-STATE | HANDLE  |
|-------------------|------------|---------|
| not loaded        | NIL        | NIL     |
| statically linked | :STATIC    | NIL     |
| dlopen()'d        | :EXTERNAL  | non-NIL |

This is useful for very large enumerations of which we're only interested in a subset, or enumerations that allow for arbitrary client or vendor extensions that we cannot be aware of. Erroring on a value that we ostensibly do not care about in such a situation is not desirable, and instead simply passing through the integer allows handling the interesting cases easily in a CASE or something similar.

Add item to cl:*features* (or another list) if the given name is known
to the C preprocessor. Intended to be used when a C library defines
preprocessor constants if it includes a certain feature.

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.

To return manual examples to working state again

Fixes launchpad bug #1414277.

Evaluated expressions in *FOREIGN-LIBRARY-DIRECTORIES* (and
*DARWIN-FRAMEWORK-DIRECTORIES*) can now return a list of pathnames.

Also, by default failure to execute pkg-config is fatal and it takes a
single pkg rather than a list.

These features are already supported by constantenum definitions, we just make
them available for bitfields.

* Remove suggestion of C++ support in CFFI. It probably referred to the
  Verrazano project. There are currently no plans to support C++ in CFFI.
* cffi-grovel has been integrated into CFFI.
* Make it slightly easier to run the tutorial code on MacOS X.

Improved the documentation for Foreign Structure Types to more clearly
describe the behavior of mem-aref under the new structure reference
syntax and the compatibility of the bare structure reference with the
old behavior.
