FENIX_main/notes/libk stuff

(Almost) all of this will be in libc as well, but this stuff should be a part
of libk (the libc makefile's FREE_OBJS variable). Anything not on this list
that the kernel will need that isn't otherwise a part of the libc is probably 
best put in kernel dev, rather than in libc dev (e.g. info on the elf format 
or endianness). This also isn't a complete list. This is based off what the 
Linux klibc has that overlaps with what a POSIX-compliant libc has. We may need 
to add more from the POSIX libc, and I may have not put in dependencies here or
there (types that are needed, or macros, or functions, or whatever).

X - complete; ~ - prototype exists; ? - not sure if done
Unless otherwise specified, *() denotes a function, *[] an array variable,
* \* a pointer, [A-Z_0-9]+ a macro, [a-z_0-9] a variable or type, and anything
prefixed with struct is a struct.
(hello() is a function, hello[] is an array, hello * is a pointer, HELLO is a
 macro, HELLO() is a function macro, hello is a variable or type, and 
 struct hello is a struct.)
