1570e67881 Kernel: Allow again to boot with partitioned disk
This change ensures that we don't return a zero value blindly
from DiskPartition write/read methods.

Fixes #1719.

f614f0e2cb Kernel: Add typed_map<T>(PhysicalAddress) and use it in ACPI parsing
There was a frequently occurring pattern of "map this physical address
into kernel VM, then read from it, then unmap it again".

This new typed_map() encapsulates that logic by giving you back a
typed pointer to the kind of structure you're interested in accessing.

It returns a TypedMapping<T> that can be used mostly like a pointer.
When destroyed, the TypedMapping object will unmap the memory. :^)

4644217094 Kernel: Remove "non-operational" ACPI parser state
If we don't support ACPI, just don't instantiate an ACPI parser.
This is way less confusing than having a special parser class whose
only purpose is to do nothing.

We now search for the RSDP in ACPI::initialize() instead of letting
the parser constructor do it. This allows us to defer the decision
to create a parser until we're sure we can make a useful one.

c8b309a3b5 Kernel: Simplify PCI::MMIOAccess segment storage
Instead of nesting a bunch of heap allocations, just store them in
a simple HashMap<u16, MMIOSegment>.

Also fix a bunch of double hash lookups like this:

    ASSERT(map.contains(key));
    auto thing = map.get(key).value();

They now look like this instead:

    auto thing = map.get(key);
    ASSERT(thing.has_value());

e1709a0904 Kernel: Remove an unnecessary layer of indirection in the PCI code
The PCI access layer was composed of a bunch of virtual functions that
did nothing but call other virtual functions. The first layer was never
overridden so there was no need for them to be virtual.

This patch removes the indirection and moves logic from PCI::Access
down into the various PCI::get_foo() helpers that were the sole users.

c8087a42fc Kernel: Move more things from init() to init_stage2()
The purpose of init() is to get multi-tasking up and running. We don't
want to do anything in init() that doesn't advance that goal.

This patch moves some things from init() to init_stage2(), and adds a
comment block explaining the split.

a harddrive essentially).

1d468ed6d3 AK: Stop allowing implicit downcast with RefPtr and NonnullRefPtr
We were allowing this dangerous kind of thing:

RefPtr<Base> base;
RefPtr<Derived> derived = base;

This patch changes the {Nonnull,}RefPtr constructors so this is no
longer possible.

To downcast one of these pointers, there is now static_ptr_cast<T>:

RefPtr<Derived> derived = static_ptr_cast<Derived>(base);

Fixing this exposed a ton of cowboy-downcasts in various places,
which we're now forced to fix. :^)
