Split setenv/unsetenv by platform
...
Windows apparently doesn't have unsetenv() at all, so use the WinAPI
native envar functions instead of the usual C ones.

Reorganize error functions and includes
...
These functions are complicated because they need to be marked
"noreturn" for the compiler. There are several fundamentally
incompatible ways of doing that. Since we have only a few "noreturn"
functions, let's just list all of those in one header file of which
there is a completely different version for each compiler.

Rename fs*.c -> os*.c
...
I planned to put just the file system routines into these files, but
there are starting to be so many of them that I don't want to
duplicate the same set for networking, subprocesses etc.

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.

Unify preprocessor checks for win32
...
<https://sourceforge.net/p/predef/wiki/OperatingSystems/ > says that _WIN32 is
always defined for both 32-bit and 64-bit versions of Windows.

Remove unnecessary ifdef about unsetenv() return value
...
Posix now mandates that unsetenv() must return -1 and set errno on error.

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.

Remove time.string and time.fromstring builtins

They are of dubious value, and the C implementation uses #if.

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.
