Before these changes, only V8 added postmortem metadata to Node's binary, limiting the possibilities for debugger's developers to add some features that rely on investigating Node's internal structures. These changes are first steps towards empowering debug tools to navigate Node's internal structures. One example of what can be achieved with this is shown at nodejs/llnode#122 (a command which prints information about handles and requests on the queue for a core dump file). Node postmortem metadata are prefixed with nodedbg_. This also adds tests to validate if all postmortem metadata are calculated correctly, plus some documentation on what is postmortem metadata and a few care to be taken to avoid breaking it.

Redefining private breaks any private inheritance in the included files. We can simply declare GenDebugSymbols() as friends in related classes to gain the access that we need.
