This is the first of two rather big changes to clean up includes throughout the project. In this commit, the implicit semi-dependency on libc that bonnibel adds to every module is removed. Previously, I was sloppy with includes of libc headers and include directory order. Now, the freestanding headers from libc are split out into libc_free, and an implicit real dependency is added onto this module, unless `no_libc` is set to `True`. The full libc needs to be explicitly specified as a dependency to be used. Several things needed to change in order to do this: - Many places use `memset` or `memcpy` that cannot depend on libc. The kernel has basic implementations of them itself for this reason. Now those functions are moved into the lower-level `j6/memutils.h`, and libc merely references them. Other modules are now free to reference those functions from libj6 instead. - The kernel's `assert.h` was renamed kassert.h (matching its `kassert` function) so that the new `util/assert.h` can use `__has_include` to detect it and make sure the `assert` macro is usable in libutil code. - Several implementation header files under `__libj6/` also moved under the new libc_free. - A new `include_phase` property has been added to modules for Bonnibel, which can be "normal" (default) or "late" which uses `-idirafter` instead of `-I` for includes. - Since `<utility>` and `<new>` are not freestanding, implementations of `remove_reference`, `forward`, `move`, and `swap` were added to the `util` namespace to replace those from `std`, and `util/new.h` was added to declare `operator new` and `operator delete`.
