AK: Add Retained<T>, like RetainPtr, but never null.
...
Also use some Clang attribute wizardry to get a warning for use-after-move.

Ext2FS: Don't copy more than sizeof(ext2_inode) bytes of raw inode data.
...
Some file systems have inodes larger than sizeof(ext2_inode) so this would
stomp all over unrelated data.

Kernel: Start adding various file system permission checks.
...
Fail with EACCES in various situations. Fix userland bugs that were exposed.

Add a simple /bin/df which gathers its info from /proc/df.

Kernel: Add link() syscall to create hard links.
...
This accidentally grew into a little bit of VFS cleanup as well.
Also add a simple /bin/ln implementation to exercise it.

Ext2FS: Lock a lot. Go way overkill with locking for now.

Kernel: Make BochsVGADevice a BlockDevice and support mmapping it.
...
Currently you can only mmap the entire framebuffer.
Using this when starting up the WindowServer gets us yet another step
closer towards it moving into userspace. :^)

Ext2FS: Fix various bugs in inode and block allocation.
...
I had the wrong idea about how group indices work, so using a larger fs
with more than one group caused all kinds of mess.

Ext2FS: Fix broken logic for accessing inode and block bitmaps.

This logic only worked for the very first block group.

IDEDiskDevice: Detect disk errors and report failure to clients.

Previously we'd just fail silently if there was an I/O error of any kind.

Kernel: Invalidate file-backed VMO's when inodes are written.
...
The current strategy is simply to nuke all physical pages and force
reload them from disk. This is obviously not optimal and should eventually
be optimized. It should be fairly straightforward.

Make stat() work on device files again.
...
FileDescriptor will now keep a pointer to the original inode even after
opening it resolves to a character device.
Fixed up /bin/ls to display major and minor device numbers instead of size
for device files.

Fix dumb bug in HashTable::clear().
...
We forgot to clear the m_buckets pointer. This meant that multiple calls to
clear() would cause trouble.

Implement basic chmod() syscall and /bin/chmod helper.
...
Only raw octal modes are supported right now.
This patch also changes mode_t from 32-bit to 16-bit to match the on-disk
type used by Ext2FS.
I also ran into EPERM being errno=0 which was confusing, so I inserted an
ESUCCESS in its place.

Add support for removing directories.
...
It's really only supported in Ext2FS since SynthFS doesn't really want you
mucking around with its files. This is pretty neat though :^)
I ran into some trouble with HashMap while working on this but opted to work
around it and leave that for a separate investigation.

Kernel: Get rid of Unix namespace.

This is no longer needed as the Kernel can stand on its own legs now
and there won't be any conflict with host system data types.
