      GHCi needs to link in packages eagerly if they're specified on the

      Terrible hack to restore CAF handling behaviour in GHCi (it's
      currently broken).
      The story used to be this: in newCAF(), if the CAF is in dynamically
      loaded code, then we save the CAF's info ptr in a spare slot in the
      closure, and add the CAF to the caf_list.  The GC will retain
      everything on the caf_list.  At any point the CAFs can all be reverted
      by replacing their info pointers from the saved copies.
      CAFs need to be retained for GHCi because they might be required in a
      future execution; an optimisation would be to avoid retaining the CAFs
      if we're in "revert mode"; i.e. the CAFs are all going to be reverted
      after execution anyway.  Also, this only applies to CAFs in compiled
      code; CAFs in interpreted code are currently always retained.
      Anyway, the old story is harder now that I removed the code that
      checks whether a pointer is dynamically loaded or not (:-)).  Rather
      than re-instate that code, I created a new version of newCAF
      (newDynCAF), and arranged that the dynamic linker redirects any
      references to newCAF to point to newDynCAF instead.  The result is
      more efficient than before, and takes less code.

      Include a static version of deRefStablePtr in case the code that uses
      it was compiled without optimisation (and therefore doesn't get the
      inlined version).

      "Auto" packages.
      The big change here is that it is no longer necessary to explicitly
      say '-package X' on the command line if X is a package containing
      hierarchical Haskell modules.  All packages marked "auto" contribute
      to the import path, so their modules are always available.  At link
      time, the compiler knows which packages are actually used by the
      program, and it links in only those libraries needed.
      There's one exception: one-shot linking.  If you link a program using
          ghc -o prog A.o B.o ...
      then you need to explicitly add -package flags for each package
      required (except base & haskell98) because the compiler has no
      information about the package dependencies in this case.
      Package configs have a new field: auto, which is either True or False.
      Non-auto packages must be mentioned on the command-line as usual.
      Non-auto packages are still required for:
        - non-hierarchical libraries (to avoid polluting the module namespace)
        - packages with no Haskell content
        - if you want more than one version of a package, or packages
          providing overlapping functionality where the user must decide
          which one to use.
      Doc changes to follow...

      Correctly describe the stack during a GHCi CCALL instruction to the
      RTS.  The previous hack, temporarily truncating the stack to the
      topmost valid stack frame, didn't work because stack-squeezing tends
      to move the stack around before the call.
      The right thing to do is correctly describe the chunk of ccall args
      with an info table, which is what this change does.  We use a RET_DYN
      info table with the number of non-ptrs from the CCALL instruction.

      Fix recent breakage on the HEAD.  This was caused by the fix to
      Lex.lhs to treat primitive strings as "narrow" FastStrings in all
      cases, rather than Unicode ("wide") FastStrings if the string
      contained a '\0'.  The problem is that narrow FastStrings aren't set
      up to handle strings containing '\0'.  They used to be, but it got
      broken somewhere along the line.
      This commit:
       - remove the '\0' test from unpackCStringBA (it takes a length
         argument anyway), and rename it to unpackNBytesBA.  This fixes
         the bug.
       - remove the '\0' terminator from all strings generated by the
         functions in PrimPacked.  The terminators aren't required,
         as far as I can tell.  This should have a tiny but positive
         effect on compile times.

      When lexing a primitive string, always make a "narrow" FastString.
      Otherwise when the string contains zeros we get a Unicode string,
      which luckily turns into the right thing when compiled but confuses the
      byte-code generator.
      So this fixes the symptom (byte-code generator can't load files
      generated with happy -ag), but not the real bug (byte-code generator
      can't handle unicode strings).

      Shortcut when switching evaluators: instead of going round the normal
      scheduler loop, just cut to the chase and run the thread using the
      other evaluator.
      This avoids doing stack squeezing each time we switch evaluators,
      which is an O(n) operation these days, whereas it used to be O(n) the
      first time, and O(1) thereafter if the stack hadn't changed too much.
      This is a problem that we should perhaps address separately, but for
      now the workaround should provide a speed boost to GHCi on the HEAD.

      A modification to the way we build link lines.
      Currently the link line is constructed like this, for packages p1, p2 etc.:
        libraries p1 ++ extra_libs p1 ++
        libraries p2 ++ extra_libs p2 ++
        extra_ld_opts p1 ++
        extra_ld_opts p2 ++
      This change makes it follow this pattern:
        libraries p1 ++ extra_libs p1 ++ extra_ld_opts p1 ++
        libraries p2 ++ extra_libs p2 ++ extra_ld_opts p2 ++
      which seems more useful: in particular it means that using foo-config
      (eg. gtk-config) to populate extra_ld_opts should now work properly,
      and extra_libs is no longer strictly speaking needed (you can just use
      -l options in extra_ld_opts and get the same effect).
        - There's now no difference between -l<lib> and -optl-l<lib>
        - GHCi grabs libs from extra_ld_opts as well as extra_libs

      Sigh, I thought I could keep this file private to the RTS, but sadly
      it's needed in order to #include RtsFlags.h, and we advertise
      RtsFlags.h as a way to tweak flags through defaultsHook().  Oh well.
