src/base/Jamfile, src/base/rules.mk: adding trigonometric functions
to the core API (using Cordic algorithms).
* builds/top_level.mk, builds/newline, builds/detect.mk: fixed problems
with Make on Windows 2000, as well as problems when "make distclean" is
invoked on a non-Unix platform when there is no "config.mk" in the
current directory..
* builds/freetype.mk: fixed a problem with object deletions under
Dos/Windows/OS/2 systems
* src/tools: added new directory to hold tools and test programs
moved docmaker.py, glnames.py to it..
* src/tools/docmaker.py: improved the script to add the current date
at the footer of each web page (useful to distinguish between versions)
* Jamfile: fixed incorrect HDRMACRO argument.
* TODO: removed the cubic arc bbox computation note, since it has been
fixed recently..
* include/freetype/t1tables.h, include/freetype/config/ftoption.h:
formatting
