test: add TAP output to the test runner

This is a back-port of commit 14ed173 from the master branch.
zlib: fix assert on bad input

The following test case occasionally triggered an assert because
write_in_progress_ didn't get cleared on error:

  $ cat test.js
  require('zlib').gunzip('BAM', console.log);
  setTimeout(gc, 10);

  $ while true; do node --expose-gc test.js || break; done
  { [Error: incorrect header check] errno: -3, code: 'Z_DATA_ERROR' }
  Assertion failed: (!write_in_progress_ && "write in progress"),
  function Clear, file ../src/node_zlib.cc, line 71.
  Abort trap: 6

Steps to avoid that:

* Initialize all primitive member fields in the constructor.
* Clear the write_in_progress_ member field in ZCtx::Error().
* Ref the ZCtx object as soon as write_in_progress_ is set to true.
  Before this commit, it could get GC'ed in the time between setting
  the field and the call to ctx->Ref().

Fixes #4783.
doc: add note about child process line buffering

Fixes #4808.
http: Handle hangup writes more gently
crypto: fix base64 padding regression

Commit 9901b69c introduces a small regression where the trailing base64
padding is no longer written out when Cipher#final is called. Rectify
that.

Fixes #4837.
stream: Start out in sync=true state

The Readable and Writable classes will nextTick certain things
if in sync mode.  The sync flag gets unset after a call to _read
or _write.  However, most of these behaviors should also be
deferred until nextTick if no reads have been made (for example,
the automatic '_read up to hwm' behavior on Readable.push(chunk))

Set the sync flag to true in the constructor, so that it will not
trigger an immediate 'readable' event, call to _read, before the
user has had a chance to set a _read method implementation.
stream: Do not switch to objectMode implicitly

Only handle objects if explicitly told to do so in the options
object.  Non-buffer/string chunks are an error if not already in
objectMode.

Close #4662
http: Do not free the wrong parser on socket close

This appears to fix #4673.  That bug is very hard to reproduce, so it's
hard to tell for certain, but this approach is more correct anyway.

deps: downgrade v8 to 3.14.5

V8 3.15 and newer have stability and performance issues. Roll back to
a known-good version.
v8: reapply floating patches

Reapply floating patches. Special mention: also reapplies 017009f but
with the extra change of removing DescriptorArray::kTransitionsIndex
from the postmortem metadata generator because said field no longer
exists in V8 3.14.
