Lassi Kortela 3b13e81eae Add concept of built-in libraries and (import) statement
R7RS syntax is: (import (library name here))

We translate this into the internal path "library/name/here". This will allow
us to easily load libraries from files later on by appending the ".sld" file
name extension.

Lassi Kortela 1d96278313 Break down dirpath.c into fs_*.c by OS
I much prefer this to using ifdefs. Requires a little help from the build
system but I find it worth it.

Lassi Kortela e19fe0b8bd Remove time.string and time.fromstring builtins
They are of dubious value, and the C implementation uses #if.

Lassi Kortela d6a4029dde Replace idiosyncratic C types with standard ones
For number types, we rely on classic C types (char, short, int, long) to be
the correct sizes. For precise bit widths, use standard intN_t and uintN_t.
For size_t, just use system size_t.
