Tests can now declare flags before using them, in order to specify non-default values for the fields in 'D.Types.GenericPackageDescription.Flag'.

This fixes #4299. The change gives the dependency solver the flexibility to link dependencies when the user has only set a manual flag on one of them. Previously, the solver would force the constrained dependency to have the flag value from the constraint and force the unconstrained dependency to have the default flag value. In cases where the single instance restriction required the dependencies to be linked, the solver couldn't find a solution. Qualified constraints can still be used to force different dependencies on a package to use different flag values. For example, "--constraint 'pkg +flag' --constraint 'pkg2:setup.pkg -flag'" turns the flag on for the top-level dependency and off for the setup dependency. I also stored flag default values in the search tree to simplify the code.

This flips error handling around, so that 'die' now can format an error message with call stacks and markers before raising it to the top handler. The top handler detects "verbatim" deaths and prints them without formatting. Signed-off-by: -

Now if you say cabal -v"info +callstacks", Cabal invocations will also get call stacks. There's a heinous hack to handle version of Cabal that don't support the extended format. Signed-off-by: -

The semantic change in this diff has to do with how local signatures are treated. Previously, we threw them into the bag when mix-in linking, which means that if you declared a signature, and another package brought that module into scope, the signature would get "filled". This is actually never what you want in non-recursive Backpack, so this commit moves it so that we only put the signatures in post-facto. There is still some more sanity checking we should do but I'm deferring that for a later commit. Signed-off-by: -
New output: Error: Problem with module re-exports: - The module 'Asdf' is not exported by any suitable package. It occurs in neither the 'exposed-modules' of this package, nor any of its 'build-depends' dependencies. In the stanza 'library' In the inplace package 'Reexport2-1.0' Signed-off-by: -

I noticed that I was repeatedly writing the same code to print out more elaborate information when we do builds, so I refactored it all into one place. In the process, I think that I have made the build output more generally useful. The key changes: - There is a new function setupMessage' which takes in more information than the conventional setupMessage does, and prints a more informative message: whereas setupMessage will only tell you about the package it is being run in, setupMessage' will also tell you about the component and instantiation. - I applied this function to applicable sites, in some cases moving around messages to be closer to the place where an actual operation takes place. For example, the 'Building' message previously only was triggered at the beginning of the build process; now it is emitted immediately before we call out to GHC. This is a lot more informative, and avoids people thinking that we are slow because of preprocessing (we're not.) Something similar happened for Haddock as well.
