This change makes the error codes returned by v8.writeHeapSnapshot()
consistent across all platforms by using the libuv APIs instead of
fopen(), fwrite() and fclose(). This also starts reporting potential
errors that might happen during the write operations.

The test was failing when it was being run with superuser privileges,
so this changes the test from attempting to write to a read-only file to
attempting to write to a file with the same name as that of an existing
directory, as that is a more reliable way of making
v8.writeHeapSnapshot() throw even when run with sudo.

If the file fails to be written (e.g. missing permissions, no space left
on device, etc), `writeHeapSnapshot` will now throw an exception.
This commit also adds error handling for the `fclose` call, returning
false if a non-zero value was returned.

This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.
The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.
This has the side effect that `common` is used significantly less
frequent.

ERR_INVALID_ARG_TYPE is the most common error used throughout the
code base. This improves the error message by providing more details
to the user and by indicating more precisely which values are allowed
ones and which ones are not.
It adds the actual input to the error message in case it's a primitive.
If it's a class instance, it'll print the class name instead of
"object" and "falsy" or similar entries are not named "type" anymore.

Adds `v8.writeHeapSnapshot(filename)` with impl adapted
from the `node-heapdump` module.
Also, adds a v8.getHeapSnapshot() alternative that returns
a Readable Stream
