Add a macro to trace ccall for debugging

[odow]

x-ref #257

I don't necessarily think we should merge this, but it could be super useful for debugging.

Code like this:

using JuMP, HiGHS
HiGHS.HIGHS_LOG_FILE() = "/tmp/highs.log"
model = direct_model(HiGHS.Optimizer())
@variable(model, x >= 1, Int)
@objective(model, Min, 2 * x + 3)
@constraint(model, x <= 2)
optimize!(model)
termination_status(model)
@constraint(model, x <= 0.4)
optimize!(model)
model = nothing
GC.gc()
HiGHS.HIGHS_LOG_FILE() = nothing
model = direct_model(HiGHS.Optimizer())

gives

If the macro was: @trace ccall(...), using it would be a simple replace all. I'm not sure how easy it would be.

This might be useful to add to a JuMP extension package for debugging and linting. I have, too often, manually traced the C API when building a MWE for Gurobi et al.

More changes. As evidence, it helped me get a MWE for #202
