Kernel: Allow fchmod() and fchown() on pre-bind() local sockets
...
In order to ensure a specific owner and mode when the local socket
filesystem endpoint is instantiated, we need to be able to call
fchmod() and fchown() on a socket fd between socket() and bind().
This is because until we call bind(), there is no filesystem inode
for the socket yet.

Ext2FS: Take the inode lock in Ext2FSInode::metadata()
...
Remove an unnecessary InterruptDisabler to make this not assert. :^)

Kernel+SystemMonitor: Log amounts of I/O per thread
...
This patch adds these I/O counters to each thread:
- (Inode) file read bytes
- (Inode) file write bytes
- Unix socket read bytes
- Unix socket write bytes
- IPv4 socket read bytes
- IPv4 socket write bytes
These are then exposed in /proc/all and seen in SystemMonitor.

Kernel: Update the mtime after a successful InodeFile::write()
...
Well this was pretty silly. We were not updating the modification time
of files.. after modifying them. :^)

AK: Rename the common integer typedefs to make it obvious what they are.
...
These types can be picked up by including <AK/Types.h>:
* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

Kernel: Rename "descriptor" to "description" where appropriate.
...
Now that FileDescription is called that, variables of that type should not
be called "descriptor". This is kinda wordy but we'll get used to it.

Kernel: Rename FileDescriptor to FileDescription.
...
After reading a bunch of POSIX specs, I've learned that a file descriptor
is the number that refers to a file description, not the description itself.
So this patch renames FileDescriptor to FileDescription, and Process now has
FileDescription* file_description(int fd).

Kernel: Memory-mapped files now have the absolute path as their name.
...
It's generated when the mapping is first created, so it won't update if
the file moves. Maybe that's something we should support, too.

Kernel: Make the Process allocate_region* API's understand "int prot".
...
Instead of having to inspect 'prot' at every call site, make the Process
API's take care of that so we can just pass it through.

Kernel: Add InodeFile, a File subclass for regular files.
...
Finally everything that can be held by a FileDescriptor actually inherits
from the File class.
