9a935bdd0f Provide convenience accessors for public signals in C++ and Rust 
Typically their emission requires an evaluation context parameter.
Similar to properties, provide a public emitter function that takes care
of the context.

This also required two fixes in the compiler, in order to make the
following (as part of the test case) work:

    signal foo;
    foo => { ... }

    (1) Register declared signals before attempting to implement the
    connection handlers.
    (2) When looking up the signal property, not only look in the base
    type but also in the current type.

be3d0ab369 Provide convenience accessors for public properties in C++ 
While properties declared in the root component are named as-is and
exposed as Property<T>, their get() function in particular is hard to
use because it requires an EvaluationContext as a parameter.

This patch adds get_foo() and set_foo() accessors for each public
property and hides the evaluation context business for the getter.

The added test uses this right away and adds missing test coverage for
the conditional expression.

1404cb73ae Add support for embedding resources in the rust generator 
This is relatively straight-forward via a pass in the compiler to
collect the resources to embed and then use include_bytes! (once per
resource).

What's really annoying is that the rust resource enum can't store a
&'static [u8] because cbindgen doesn't represent that, probably because
the slice representation isn't guaranteed to stay as it is. So instead
this, for now, uses raw pointers.

96d5165d28 Correctly report type conversion errors in the C++ backend 
This requires a bit of error propagation, but now the errors are
reported correctly, in the unlikely event that they occur.

a39a72b240 Fix the syntax_tests to actually match the regexp 
The error regexp was not properly matched, being effectively ignoed.
Fixed that and the tests.
Added self tests to syntax_tests.
