Lassi Kortela 5ced8d91f6 Store boot image inside main executable
Previously the boot image was kept in the separate file "flisp.boot".
This caused all kinds of problems, as bootstrapping is wont to do. The
biggest problem was finding a portable and convenient pathname for it.

Instead of dealing with all that stuff about how to find the file,
just store the image in a huge C string constant that goes into the
main executable. This necessitates adding a C-string hex dumper into
the Lisp system, and making build.sh slightly more complicated, but
that's a small price to pay for not having to carry a separate file
everywhere we go. Also, flmain.c is a lot simpler now and we don't
have to play around with symlinks.

Lassi Kortela 71098dd01b Fix some "long double" nonsense
Apparently in addition to "float", "double" and "long double" there
are now standard types in <math.h> called "float_t" and "double_t".
Those types don't need to be equivalent to "float" and "double". Gah!

Lassi Kortela 4a89521493 Use 'int' instead of 'char' for character variables
MINIX libc headers define the ctype.h toupper() etc. functions as
preprocessor macros that don't cast their argument to int! So a char
argument causes clang to say "warning: array subscript is of type
'char'".

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 2ec07684d2 Get OS name from uname()
This implies that OS names have changed. Unix-like OS names are now
capitalized. "macos" is now "Darwin". Windows is now all-lowecase "windows".
"win32" is gone. "win64" was not used in the original code despite a reference
to it.

Lassi Kortela 95a1c1032c Remove ifdef about memrchr() on MacOS
MacOS doesn't have memrchr() so there was an ifdef with a custom

implementation.
