e23acfd7e7 Made slight optimizations in Sandbox2's comms. 
The optimizations are:
* Reduced the number of calls to `write` (originating from `SendTLV()`) from 3 to 1-2 (depending on size of the payload).
* Reduced the number of calls to `read()` (originating from `RecvTLV()`) from 3 to 2.

c501379056 Clang tool: Prevent extra nesting of namespaces 
When specifying the `namespace` argument in Bazel (`NAMESPACE` in CMake), the
Clang tool used to put _all_ dependent types in that namespace.

For a declaration of `namespace a::b { struct S {...};` and a `namespace`
argument of `a::b`, this means that the header output was similar to
```
namespace a::b {
namespace a::b {
struct S { ...
```

This was never intended and also does not match the Python based header
generator. The Clang tool now "merges" those same namespaces. This is
correct, as it processes `namespace`d spellings with their full namespace
path.

ae3d334cc2 generator2: Skip anonymous structs/unions 
The Python code has been relying on `spelling` to return `None` for skipping
anonymous structs/unions.

libclang has been returning a "spelling" for those for a while now (LLVM 16
introduced this in its branch in 2022), though, so this check no longer works.
Use the correct method `clang.CIndex.is_anonymous()` instead.
