838992c3d8 Don't build libmaxsi.a. 
This should just about remove most of the old and deprecated (and now
obsolete) Maxsi:: API. Of course, large parts of libc still suffer from
its poor design, but I'll get around to fix that eventually.

b685b7a9eb Don't include Maxsi:: API in kernel.cpp. 
Since kernel.cpp is intended to be an example of the current best coding
practices within the Sortix kernel, and the Maxsi:: API is deprecated and
is being removed, it should rather use the nice C standard library.

0437d75147 Remove libmaxsi stddef.h and stdarg.h. 
These are provided by the cross compiler.

b293fb3171 Remove kernel platform.h dependency on libmaxsi platform.h. 
This reduces the dependence on libmaxsi with the aim that the Maxsi:: api
can be removed and replaced with the standard C library.

17a93359dd Add . and .. support to kernel filesystems. 
This makes the hack in ls(1) not needed and is hence removed.

755e855c08 Renamed sforkr(2) to tfork(2). 
It's a much better name if you think of it as task-fork or thread-fork in the
sense that it either modifies this task or creates a new one. This call will
be used to provide user-space threads as well as fork(2).

7d39906acc Added support for saving FPU registers upon context switch. 
This code uses the cr0 task switched bit to disable the FPU upon task
switch, which allows the kernel to delay copying the registers until
another task starts using them. Or better yet, if no other thread actually
uses the registers, then it won't need to do any copying at all!

93bb4f992b Added support for floating point numbers. 
Note that the scheduler does not load/restore floating point numbers yet
upon task switching. This means only one task can use floating point numbers
at the same time without the risk of race conditions.

Note that this enables SSE in 32-bit x86 platforms - but not all models
have such support, which limits which computers Sortix works on. Ideally, we
should detect what features are available on the computer at runtime and
enable/disable the proper kernel support. This is not a problem on x86_64.
