Improvements to HostEd

[mikee47]

This PR proposes some changes to the Hosted classes

Update simpleRPC to master

With clang-tidy #2648 some failures occur in the simpleRPC library. Updating this to current master solves the issues.
I've also put all the code into the simpleRPC namespace which sorts out the conflict with Vector but makes it available for use if required.

Tidy HostTests module

Also decode the anonymous 'packet' blob so we can see what's in it and compare with spec. should we wish to update it.

Use abstract base class for callbacks

Simplifies implementation since usually all callbacks are required.
Compiler ensures all methods have implementations.
clang-tidy gave potential memory leak indication because of Delegates. Not sure if that's real but this fixes it.

@mikee47 I am trying to compile the Basic_Blink using the command below and I get compilation error?!

cd $SMING_HOME/../samples/Basic_Blink
make SMING_ARCH=Host ENABLE_HOSTED=tcp HOSTED_SERVER_IP=192.168.4.1

The error is:

static_assert(sizeof(time_t) == 8, "Expecting 64-bit time_t");

Any idea how to work around this issue?

... Expecting 64-bit time_t

I'm going to guess your version of GCC is old; I'm with Fedora on GCC 13.2.1 - what version are you using?

[slaff]

what version are you using?

Gcc version 9.4.0. I will check if I can upgrade on my Ubuntu 20.04 LTS ...

[slaff]

Gcc version 10.5.0 is the latest GCC that I can use ... Hm.. have to think about OS upgrade ...

That should be fine #2758

You can just comment out that assert - I put it there deliberately so we'd know about this sort of thing!

@slaff You'll doubtless have run into the other issue attempting to build Basic_Blink for Hosted using a tcp connection: DISABLE_NETWORK is hard-coded in component.mk and has to be changed. I'm thinking that's probably just something to bear in mind using Hosted.
