Merge branch 'master' of https://github.com/chapel-lang/chapel into triage-sep-blc
Removing Cray internal URLs
Updated REGRESSIONS based on past few days run
Add warning if compiling a configuration the runtime has not (yet) built.

This is useful when, for example, compiler and runtime was compiled with
CHPL_GMP=gmp (perhaps due to speculative build) but user has manually set
CHPL_GMP=none when calling chpl compiler.

Update runtime lib dir check based on review feedback.

* Fixes the if statement to use all make functions, instead of a combination of
  bash and make.
* Promotes the warning to an error.
* Updates the message to be more clear about the issue.
Add additional messaging when CHPL_DEVELOPER is set.

Also update FIXME comment.
more wordsmithing
Add test for the new warning message.
Wrap a long line.
Factor prediff script into separate script.
Add error different messaging for module.

The module is a binary install (a la RPM), so it does not make sense to tell
the user to rebuild. Instead, tell them to send the output of printchplenv to
the package maintainer.

The exact wording is probably not final here.
Remove fixme comment.
Split the new file utilities into a separate runtime file.

qio.c was quickly going to run out of control with all the new file operations
in it, and qio wasn't necessarily the right place to put them so now these
operations will live in their own .c/.h file: chpl-file-utils.
Add test with CHPL_DEVELOPER defined.
Split new file utilities from IO.chpl to FileUtils.chpl

IO.chpl would quickly get out of hand if the new file operations were to live
there any longer, so I put them in a separate file, FileUtils.chpl.  The string
path operations, when they are developed, will live in PathOps.chpl
