between all processes.

Kernel: Rewrite and optimize DiskCache
...
DiskCache now consists of PageCaches which are caches of contiguous
sectors. This allows the disk cache to be ordered and faster traversal.
We seem to have a problem somewhere during reading. The stack gets
corrupted.

Kernel: kmalloc has now somewhat dynamic storage
...
Allocations bigger than PAGE_SIZE and those not forced to be identity
mapped are now done on a GeneralAllocator. This allows us to use kmalloc
for big allocations; bigger than the fixed 1 MiB storage.
This is still a hack and the whole kmalloc will have to be rewritten at
some point, but for now this does the job :D

Kernel: Rework syscall calling

I removed the intermediate function when calling syscalls. Now syscall
handler calls the current process automatically. Only exception is
sys_fork, since it needs a assembly trampoline for the new thread.

Kernel: Scheduler now has reschedule()

This can be called from anywhere and just causes the scheduler to
schedule the next thread. This is more efficient and verbose version
of Scheduler::set_current_thread_sleeping(0), since we don't have
to wake other threads or do other verifications.

Kernel: Big commit. Rewrite ELF loading code
...
We now load ELF files to VirtualRanges instead of using kmalloc.
We have only a fixed 1 MiB kmalloc for big allocations and this
allows loading files even when they don't fit in there.
This caused me to rewrite the whole ELF loading process since the
loaded ELF is not in memory mapped by every process.
Virtual ranges allow you to zero out the memory and to copy into
them from arbitary byte buffers.
