This new libc is mostly from scratch, with *printf() functions provided
by Marco Paland and Eyal Rozenberg's tiny printf library, and malloc and
friends provided by dlmalloc.
Part one of a series of code moves. The kutil library is not very
useful, as most of its code is kernel-specific. This was originally for
testing purposes, but that can be achieved in other ways with the
current build system. I find this mostly creates a strange division in
the kernel code.
Instead, I'm going to move everything kernel-specific to actually be in
the kernel, and replace kutil with just 'util' for generic utility code
I want to share.
This commit:
- Moves the logger into the kernel.
- Updates the 'printf' library used from mpaland/printf to
eyalroz/printf and moved it into the kernel, as it's only used by the
logger in kutil.
- Removes some other unused kutil headers from some files, to help
future code rearrangement.
Note that the (now redundant-seeming) log.cpp/h in kernel is currently
still there - these files are more about log output than the logging
system, and will get replaced once I add user-space log output.
With the new bootloader changes that use clang to directly build an EFI
application, the last piece of GNU-EFI that was used (the linker script)
is no longer necessary.
Thanks for being a great starting point, GNU-EFI!
