Kernel/LibC: remove PATH resoltion from kernel
...
I have no idea why I had made PATH environment variable parsing
to be part of the kernel. Now the shell does the parsing and
environment syscall is no longer needed.

Kernel/LibC: userspace malloc now uses mmap to get memory
...
We could remove syscalls to allocate more memory. This was not
something the kernel should have done.

Kernel/LibC: add mmap for private anonymous mappings
...
This will be used by the userspace to get more memory. Currently
kernel handles all allocations, which is not preferable.

Kernel: Userspace signal handlers are now called one at a time
...
I added a syscall for telling the kernel when signal execution has
finished. We should send a random hash or id to the signal trampoline

be confirmed.

Kernel: remove message from BAN::Error

We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.
We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.
