67c55b0b2f forth: Forth-ify ROT, a native word!
This requires us to significantly adjust our build process, which

ca7c21d49f forth: make "(entry)" call WORD itself
Otherwise, when a defining word would be called outside a definition
itself, it would get the name of the last parsed word, that is,
itself!

For example, dummy.fs, instead of creating a "_______" entry, created
a "(entry)" entry...

c1ece95089 forth: implement readline in Forth
The commit ended up being much bigger than anticipated. This was a long thread
of underlying complexities. This lead to the creation of interesting concepts
such as (sysv).

549cf74e9d forth: inline code from "apps/lib"
Forth-ification of Collapse OS goes forward. What will happen is that assembly
code in apps/ will become Forth code. The concept of an assembler code library
will become obsolete.

However, Forth's core use some of that code. To facilitate the transition, I'm
inlining that code directly in Forth's code.

5d5517ac44 forth: allow DEFINE's ";" to be at the start of a newline
Previous to this commit, DEFINE's algo would miss a ";" right after a newline.

This allows for a much nicer formatting+comment of core.fs.
