The previous fix did not work with functions that return no values.
Surround the code with braces, so that the C compiler does not
complain about the extern declaration.

Allow the ECL backend to support different combinations of FFI in
the same code by customizing a single special variable.

LONG-LONG is not supported by ECL's interpreter yet.

Using the ECL extension EXT:WITH-BACKEND, CFFI can produce code that
works differently when using the interpreter than when using the
lisp2C compiler. This leads to more efficient code. This change is
backwards compatible.

Declare DEFCALLBACK, DEFCFUN and DEFINE-FOREIGN-LIBRARY's keyword args :CCONV and :CALLING-CONVENTION obsolete, use :CONVENTION instead.

- New regression test: CALLBACKS.UNINTERNED.

Bug reported by Liam Healy.

ECL uses a non-moving, conservative garbage collector, so shareable
byte vectors can be implemented just by using a pointer to the data.

- Keep it around for backwards compatibility.
- Don't use it from CFFI itself or the test suite.
- Update the manual.

Not sure if this is a great idea yet.  In any case, CFFI-FEATURES is
still there for backwards compatibility for the time being.

- foreign-pointer: deftyped to sb-sys:system-area-pointer, ccl:macptr, etc.
- manual: document it.
- new tests: pointerp.1 and pointerp.2.

Three new features:
  - stdcall (defcfun, foreign-funcall(-pointer), defcallback)
  - namespaces, associate foreigns vars and functions to a
    specific library. (CLISP and Lispworks only)
  - close-foreign-library actually works now.

Backwards incompatible changes:
  - define-foreign-library's syntax changed slightly, can't
    load more than one foreign library per define-foreign-library
    form anymore.
  - defcvar's syntax changed.
  - foreign-funcall can't funcall pointers anymore. Use
    foreign-funcall-pointer for that.

- Use it to load foreign libraries. Using plain CL:NAMESTRING was causing
  trouble with OpenMCL where (namestring #p"foo.bar.baz") returns
  "foo\\.bar.baz".

- Fixed the port to architectures without dynamical FFI.
- Tests with too large number of arguments (> 34) are marked as
  expected to fail.

- cffi-ecl fixes:
   - push cffi-features:unix on darwin too.
   - use si:load-foreign-module instead of ffi:load-foreign-library
     on DFFI platforms.
   - use convert-external-name in foreign-symbol-pointer.
- wrap defcvar's define-foreign-symbol around eval-when.
- simplify default-library-suffix
- cffi-tests:
   - load libtest.o on ECL platforms without DFFI.
   - conditionalize the tests with 127 arguments based on the
     value of lambda-parameters-limit.

- Fixed some bitrot in cffi-ecl.lisp (maybe). Still can't test
  properly because of an ECL bug related to make-load-form.

- New functions: finalize and cancel-finalization.
- New cffi-"feature": no-finalizers. Only ECL pushes this.
- Document new functions.

- Remove second argument from foreign-symbol-pointer.
- Update foreign-symbol-pointer documentation in the manual.
- New tests: funcall.f-s-p.1 and foreign-symbol-pointer.[12].

- New cffi-sys primitive: canonicalize-symbol-name-case. Use this
  instead of read-from-string. Also new tests for this.
- cffi-scl.lisp: correct the evaluation order of %MEM-REF and %MEM-SET.
  Have 'foreign-symbol-pointer return 'nil if the symbol is not found.
- uffi-compat.lisp: better support for SCL.
- defcfun.lisp (defcfun.undefined): package at time of eval may differ
  from the compile time package.

- mention this in the manual.
- make l-f-l signal an error on non-dffi ecl platforms.

- Thanks for Luís for showing me how to configure Emacs to get this right.

- change "docs" to be the default target in doc/Makefile.
- add Stephen the list of authors in cffi-manual
- rename "Index" to "Comprehensive Index" so that Index.html doesn't
  clash with index.html on OSX.
- add varargs example for defcfun
- rename features (again) foreign-funcall -> no-foreign-funcall,
  long-long -> no-long-long.

Untested: the ECL backend does not seem to build for me.
