This move some of the complexity over to the lower level TempFile.
It also makes it a bit more explicit where errors are ignored since we
now have a call to consumeError.

std::error_code can represent success, so we don't need a
Optional<std::error_code>.
Rename the variable to avoid confusion with the type Error.

Summary:
Previously, we would emit error messages like "IO failure on output
stream". This change causes use to include information about what
actually went wrong, e.g. "No space left on device".

This is currently used by clang to lock access to modules; improve the
error message so that clang can use better output messages from locking
error issues.

5 minutes is an eternity, so try to strike a better balance between
waiting long enough for any reasonable module build and not so long that
users kill the process because they think it's hanging.
Also give the client a way to delete the lock file after a timeout.

This is a minimal change to remove the header. I will remove the occurrences
of "using std::error_code" in a followup patch.
