Release 1.3.5 of CL-Forth

Performance Improvements

Change the FORTH-SYSTEM class to a structure. Update WITH-FORTH-SYSTEM to arrange for inlined slot access

Change the WORDS, DICTIONARY, and WORD-LISTS classes to structures to get inlined slot access

Change how parameters are saved in words to use a structure, eliminating the use of APPLY in FORTH-CALL

Optimize the implementation of ACCEPT

Optimize the character "primitives" EXTRACT-CHAR, FORTH-CHAR, NATIVE-CHAR

Optimize the functions that convert between Forth strings and native strings

Use EQL instead of CHAR-EQUAL in places where the overhead of CHAR-EQUAL is superfluous

Bug Fixes

Fixes issue #1

Release 1.3 of CL-Forth

FFI improvements:

Support [OPTIONAL] with LIBRARY
Change XLIBRARY to understand that, on Linux, library names frequently end with a version number (e.g., "libc.so.6", "libcurl.so.4.6.0") instead of the ".so" suffix.
In CCL and SBCL, CFFI ignores the :library argument to cffi:foreign-funcall and cffi:foreign-symbol-pointer. Define a "libDefault" library so FUNCTION: and GLOBAL: can be used on those platforms without first loading a library.
Improve the error messages when a foreign function or global is not found.
In CCL and SBCL, omit the library name from the output of .IMPORTS as it's not accurate.
In LispWorkds, suppress CFFI's created foreign funcallable announcement.
FFI callbacks now save and restore the data and floating-point stacks locally to allow nested and/or concurrent callbacks.
Add FFI.md
Add an example of using the FFI

Other Highlights:

Add BEGIN-NAMED-STRUCTURE to create a structure whose field names will include the structure's name.
Add LFIELD: and WFIELD: to create longword (32-bit) and word (16-bit) structure fields, respectively.
Add longword (nee, 32-bit) access words L@, UL@, L!, and L,.
Add word (nee, 16-bit) access words W@, UW@, W!, and W,.
Add pointer access words P@ and P!.
Save the docstring in define-word and display it as part of the output of SEE.
Allow building standalone applications with SBCL in addition to CCL.
Catch Ctrl-C and abort to CL-Forth top level
Add STATISTICS to report some usage statistics. Also, display the statistics when exiting CL-Forth.
