modularize sex

Browse Source 
Also rename macros to sex-macros, module-system to sex-modules for
clarity, uniformity, and to avoid name clashes with Chicken's
units/modules named "macros" and "modules"

CSC_FLAGS += -K prefix -static
# What and why:
# -emit-all-import-libraries: Emit import-libraries for all defined modules.
# Used to generate .import.scm files so compiler would know how to use the modules.
# Without it, csc fails with "cannot import from undefined module" error.
# -module-registration: Always generate module registration code, even when
# import libraries are emitted. Enables us to import from our modules at run time.
# Used in macros, where we inject `(import (only sex-macros cat))' before the macro body.
# Without it, sexc compiles scuccessfully, but is unable to process macros, failing with
# "during expansion of (import ...) - cannot import from undefined module: sex-macros"
# error.
# -c: Stop after compilation to object files. This one is obvious.
