This is a large commit because it implements a lot of stuff to make
add_child simpler to get working. This allows us to create new files
on a FAT partition.
This is the first part of write support, it allows for full file
modification, but no creating or removing files yet.

Caching the cluster list allows us to fill the two fields in the
InodeMetadata. While at it, don't cache the metadata as when we
have write support having to keep both InodeMetadata and FATEntry
correct is going to get very annoying.
This has KString, KBuffer, DoubleBuffer, KBufferBuilder, IOWindow,
UserOrKernelBuffer and ScopedCritical classes being moved to the
Kernel/Library subdirectory.
Also, move the panic and assertions handling code to that directory.
* Fix bug where last character of a filename or extension would be
truncated (HELLO.TXT -> HELL.TX).
* Fix bug where additional NULL characters would be added to long
filenames that did not completely fill one of the Long Filename Entry
character fields.
Because the ".." entry in a directory is a separate inode, if a
directory is renamed to a new location, then we should update this entry
the point to the new parent directory as well.
