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

http: Handle hangup writes more gently
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.

Merge branch 'v0.8.21-release' into v0.8
Now working on 0.8.22
blog: Post for v0.8.21
ChangeLog: Missed item about EINPROGRESS
blog: Update with EINPROGRESS changelog item
doc: update instructions on home page

Document how to run the example on the home page in more detail.

Apparently our Windows brethren are prone to double-clicking on the
binary instead of running it from the command line.

Fixes #4854.
build, windows: disable SEH

Turn off safe exception handlers, they're incompatible with how
openssl is compiled / linked under MSVS 2012.

Addresses the following build error:

  openssl.lib(x86cpuid.obj) : error LNK2026: module unsafe for SAFESEH
  image. [g:\jenkins\workspace\nodejs-oneoff\node.vcxproj]
  openssl.lib(x86.obj) : error LNK2026: module unsafe for SAFESEH

  # etc. etc.
  g:\jenkins\workspace\nodejs-oneoff\Release\node.exe : fatal error
  LNK1281: Unable to generate SAFESEH image.
