That node was removed in a previous commit so let's remove it from this
document too.

This commit also updates 'checksum' to use the Core::Stream::File API.

This option, often used with only a lonely dash, allows to "simulate a
login". For now, it just changes the current directory to the home of
the new user.

Before of this patch, we supported two methods to address a boot device:
1. Specifying root=/dev/hdXY, where X is a-z letter which corresponds to
a boot device, and Y as number from 1 to 16, to indicate the partition
number, which can be omitted to instruct the kernel to use a raw device
rather than a partition on a raw device.
2. Specifying root=PARTUUID: with a GUID string of a GUID partition. In
case of existing storage device with GPT partitions, this is most likely
the safest option to ensure booting from persistent storage.
While option 2 is more advanced and reliable, the first option has 2
caveats:
1. The string prefix "/dev/hd" doesn't mean anything beside a convention
on Linux installations, that was taken into use in Serenity. In Serenity
we don't mount DevTmpFS before we mount the boot device on /, so the
kernel doesn't really access /dev anyway, so this convention is only a
big misleading relic that can easily make the user to assume we access
/dev early on boot.
2. This convention although resemble the simple linux convention, is
quite limited in specifying a correct boot device across hardware setup
changes, so option 2 was recommended to ensure the system is always
bootable.
With these caveats in mind, this commit tries to fix the problem with
adding more addressing options as well as to remove the first option
being mentioned above of addressing.
To sum it up, there are 4 addressing options:
1. Hardware relative address - Each instance of StorageController is
assigned with a index number relative to the type of hardware it handles
which makes it possible to address storage devices with a prefix of the
commandset ("ata" for ATA, "nvme" for NVMe, "ramdisk" for Plain memory),
and then the number for the parent controller relative hardware index,
another number LUN target_id, and a third number for LUN disk_id.
2. LUN address - Similar to the previous option, but instead we rely on
the parent controller absolute index for the first number.
3. Block device major and minor numbers - by specifying the major and
minor numbers, the kernel can simply try to get the corresponding block
device and use it as the boot device.
4. GUID string, in the same fashion like before, so the user use the
"PARTUUID:" string prefix and add the GUID of the GPT partition.
For the new address modes 1 and 2, the user can choose to also specify a
partition out of the selected boot device. To do that, the user needs to
append the semicolon character and then add the string "partX" where X
is to be changed for the partition number. We start counting from 0, and
therefore the first partition number is 0 and not 1 in the kernel boot
argument.

This commit adds manpages for About(1), AnalogClock(1), Assistant(1),
Browser(1), Calculator(1), and Calendar(1).

I tested the grub image under VirtualBox and it appeared that the image
didn't have pci.ids file included in the /res directory. In that case it
would be expected that lspci can still function correctly if the -n
parameter is passed, but then the unveil syscall failed because the file
didn't exist.
To cope with this, we should allow lspci to work without the pci.ids
file being present at the filesystem, so let's not unveil this file if
the -n parameter is passed.

The generate-manpages script needs to be updated again to handle the new
PNGs in section 1. (I'm intentionally not making this a multi-directory
glob.)

The documentation is largely unchanged except for adoption into the
standard manpage format.

Similar to `W^X` and `wxallowed`, this allows for anonymous executable

Just "Playground" is too generic and doesn't match the general rule of
"application name equals display name minus spaces".

This is far from explaining all implications of the new layout system,
but it covers the basics.
