Needed to pass in the message as a parameter to the clearer thunk!
Now the clear() augmentations in accessors_test.rs are working as expected.

Crate names must not contain '-'. So we replace any '-' by a '_' to form a valid crate name.
Bazel supports many special characters as target names: !%-@^_"#$&'()*-+,;<=>?[]{|}~/. We don't have to support all of them in Protobuf Rust, but '-' seems used widely enough and is a common alternative to '_' in naming.

Add convenience _opt for singular message fields.
Users can detect if the message is set or unset, and unwrap via into_inner.

This is the final CL (part 4 of 4) in the ProxiedWithPresence chain.
In the past, we had returned Mut directly for the `_mut` accessors.
This was a temporary engagement in order to get the other submsg machinery checked in.
As we prep for the finalization of v0.6, we can finally conform to the rest of the `_mut` getters.
$field$_mut now correctly returns $pb$::FieldEntry<'_, $msg_type$> as a part of this.
All test callsites have been updated to `.or_default` in order to test the mutational pathway as before.

Before this change if a field type was defined in a imported .proto file then our codegen would not generate the field. After this change such fields are correctly generated (see tests). This change is rather trivial as all the supporting infra has been implemented as part of the .proto -> crate mapping CLs.

- Only prepend r# to fields when needed instead of always
- Append '__mangled_because_symbol_is_a_rust_raw_identifier' to names like 'Self' which can't be used legally even with an r# prefix
Also use the same check to prepend r# on:
- Message names (eg `message Self {}`)
- oneof names
- oneof case names
- enum names
- enum case names
- module names (e.g. 'package google.type')

We now support fields with bytes as map values e.g. map<i32, bytes>. The implementation for the C++ runtime was straightforward. The majority of the changes in this CL are about the UPB runtime. In UPB, when we insert Rust bytes/string into the map we need to first copy the bytes onto the maps arena. To support this I have rewritten the macro that implements the ProxiedInMapValue types. I refactored the functionality to convert between UPB and Rust types into the 'UpbTypeConversions' trait. This trait has a function 'to_message_value_if_required' which does the copying for bytes and strings.

This will enable us to get the correct crate names for Rust gencode. The actual
reading of the mapping file in protoc happens in the followup.

If this took a &self there were holes in thread and memory safety, because it's allowed to get multiple &MsgMuts (but only &mut MsgMuts).

This change is a pure refactoring and simplification of the code. We replace all MapsWith<TYPE>KeyOps traits through a single generic ProxiedInMapValue<K> trait. Through connecting the runtime maps implementation with Proxied the code gets a lot simpler e.g. we can use View<T> instead of hardcoding the concrete type behind it.
I also expect this change to be beneficial for the gencode. In a subsequent CL we'll implement message values for maps. After this change we'll only have to implement a single trait, while before we had to implement num(key types) many traits.

For the cpp runtime, call the `Message::CopyFrom` method.
For the upb runtime, expose the message `MiniTable` and call `upb_Message_DeepCopy`.

To satisfy the layering check, we need to depend on :gtest for the headers, in
addition to :gtest_main which provides the main() function.
There are a bunch of formatting changes as a side effect of this, but they
should be harmless.

We augment the TYPE_STRING block inside message.cc:GetterForViewOrMut so that we properly return a Mut for strings when it comes to submessages.

This significantly simplifies the internals of PrimitiveMut,
and removes the need to refactor BytesMut and ProtoStrMut
to have the same runtime branching.

This change implements maps with keys and values of type string e.g. Map<ProtoStr, i32> and Map<ProtoStr, ProtoStr>.
Implementing the Map type for ProtoStr has been different from scalar types because ProtoStr is an unsized type i.e. its size is not known at compile time. The existing Map implementation assumed sized types in many places. To make unsized types fit into the existing code architecture I have added an associated type 'Value' to the MapWith*KeyOps traits. The associated type needs to be sized and is the type returned by the Map::get(self, key) method e.g. for aProtoStr, the `type Value = &ProtoStr`.
