libluna: Stop checking initialization status on every bitmap method call
...
Since our asserts (expect()) are enabled on release as well, this is kinda expensive.
It's up to the caller, if they receive a null pointer dereference it's
their fault for not initializing their bitmap :)
We do still assert out-of-range indexing and stuff like that.

libluna: Add the clear_data() method to Vector and use it to optimize Base64::decode
...
This method clears the Vector's data without deallocating the
backing buffer, so that it can be reused without reallocation.

kernel: Update the VM allocator for userspace to use a linked list
...
This can cover the entire address space at once in a more memory-efficient way.
Stress-tested using 'base64 /bin/ls' which allocates enough contiguous
virtual memory to store the entirety of /bin/ls :)
A couple of bugs and fixes later, here we are!
