Update per review. Removing const from header where it isn't needed.

Looks good apart a removed const. (the same question in D11052).

I don't think other code within LLDB really uses const scalar parameters and they don't provide much protection against anything. (They don't do anything for the caller and they only provide a minor restriction for the callee.)

Some const were removed in the MIuint to size_t patch as well, but if we decide to keep this, I can sort through and add them back.

The value of these const annotations isn't clear though.

the same here: (R) means 'readonly' variable. i.e. you will not plan to return anything through that variable.

Ok. I agree about const for scalar and any other types in arguments: we shouldn't use const for variables that are passed by value.

Fix one inline comment and go ahead.
