Document all sorts of C debugging tips

[timholy]

Fulfills a pledge I made on on julia-dev. This moves some info I wrote from the FAQ to the "developer docs", and blatantly steals from sources posted by @ihnorton and @staticfloat. Finally, there's a small number of whitespace changes.

FWIW, I usually start julia directly under gdb. I think the only time I have used separate processes is when running julia under valgrind. (perhaps it is a matter of taste though?)

[staticfloat]

Me as well.

What's funny is that I'd swear Ctrl-C did not interrupt to gdb when I first tried it oh-so-long ago. So that's why I figured this out.

It might be because of the new REPL.

thanks @timholy - what's the right conflict resolution for

Pick the second one. Surprised there was a conflict...

Thanks for doing it!

No problem, backported in 507a4c6

I think the conflict might be because devdocs/meta was not backported?
