Rehash of nodejs/node-v0.x-archive#25342 with noted corrections.

Fixes #2860, nodejs/node-v0.x-archive#9445

I've also created another variant of this solution by adding a "\n" to the wrapper and setting the lineOffset property to -1, re: tflanagan@9d8e6a9

Are there any side effects of using the second commit (tflanagan@9d8e6a9)? It seems way simpler.

I've updated the docs in two places with the lineOffset and columnOffset parameters, and also added a missing filename and timeout parameter listings.

I agree with @brendanashworth that the other commit looks much simpler. Does it cause any issues on Windows?

bump for LTS? Don't want this PR to end up like @brendan0powers's

@tflanagan does tflanagan@489b5b4 cause any issues (perhaps windows)? I think this should be pushed instead of the other bigger commits. But this would be a candidate for LTS back-porting anyways.

I've beening running it on windows for over 3 weeks without issues, granted any issue would only show if an error occured

@tflanagan could you push only that commit to this PR then? Then we can review and run the CI.

Besides for those pesky flaky Buffer tests, it passes local tests fwiw

Because Node modules are wrapped, errors on the first line
of a file leak the wrapper to the user and report the wrong
column number. This commit adds a line break to the module
wrapper so that the first line is treated the same as all
other lines. To compensate for the additional line, a line
offset of -1 is also applied to errors.

In dfee4e3, the module wrapper
and line offset used when wrapping module code was changed to
better report errors on the first line of modules. However, that
commit did not update the runInThisContext() call used to
execute the core modules, so their error line numbers have been
off by one. This commit provides the correct lineOffset for core
modules.
