This commit adds a re-implementation of hw/char/pl011.c in Rust.

How to build:

1. Configure a QEMU build with:
   --enable-system --target-list=aarch64-softmmu --enable-rust
2. Launching a VM with qemu-system-aarch64 should use the Rust version
   of the pl011 device

Some of these subprojects should be moved to patch 8, for the macro to compile.

One small thing that I forgot about, is that the init function should be unsafe.

For a short term change after this is merged, this should take not a
&mut self, but a "obj: &mut MaybeUninit<Self>".

It needs a utility macro like

fn uninit_field_mut<'a, U>(dest: *mut U) -> &'a mut MaybeUninit<U> {
    unsafe { &mut *(dest.cast()) }
}

macro_rules! uninit_field_mut {
    ($container:expr, $field:ident) => {
        $crate::uninit_field_mut(unsafe {
             std::ptr::addr_of_mut!((&mut *$container.as_mut_ptr()).$field)
        })
    }
}

and initialization code like

    p_clock = uninit_field_mut!(self, clock);
    p_clock.write(NonNull::new(...));

and it's clearly less pretty; but it avoids comments like

    // self.clock is not initialized at this point; but since
`NonNull<_>` is Copy,
    // we can overwrite the undefined value without side effects.

and it is safer because MaybeUninit<> prevents calling other functions
of PL011State too early.

It would be nice to just add a TODO here, but it's not necessary.

+# PL011 QEMU Device Model
+
+This library implements a device model for the PrimeCell® UART (PL011)
+device in QEMU.
+
+## Build static lib
+
+Host build target must be explicitly specified:
+
+```sh
+cargo build --target x86_64-unknown-linux-gnu
+```
+
+Replace host target triplet if necessary.
+
+## Generate Rust documentation
+
+To generate docs for this crate, including private items:
+
+```sh
+cargo doc --no-deps --document-private-items --target x86_64-unknown-linux-gnu
+```
+
+To include direct dependencies like `bilge` (bitmaps for register types):
+
+```sh
+cargo tree --depth 1 -e normal --prefix none \
+ | cut -d' ' -f1 \
+ | xargs printf -- '-p %s\n' \
+ | xargs cargo doc --no-deps --document-private-items --target x86_64-unknown-linux-gnu
+```
