Fixes "test/simple/test-process-exit.js".

Converting strings and others to objects is very slow and essentially
wrong.

Closes #2330

Remove reference count check. Unbreaks test suite. This needs to be addressed.

Check for potentially exploitable overflows in asn1_d2i_read_bio
BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
in CRYPTO_realloc_clean.

Taken from OpenSSL CVS. Addresses CVE-2012-2110.

Upon "normal" exiting of Node (i.e. the event loop completes naturally),
the "code" parameter was not being passed to the "exit" event listeners.

Be consistent. Tests included.

Test included.

It was a temporary thing for the 0.6 branch only.

Useful in tracking down or at least demonstrating memory leaks.

Otherwise multicode compile doesn't work.

There are some paths here that led to dangling contexts. By being
smarter with handle management we can get rid of all the cleanup code
and fix those issues.

For example, there's a global "toString()" function, so the REPL's
tab completion should pick that up.

Ref #3140

This is for scripts being fed from stdin:

  $ echo "{ foo: 'bar' }" | node -p

Reusing the same logic for both places for the behavior is consistent.

For example:

  $ ./node -p -e "'Hello World'"
  Hello World

  $ echo "'Hello World'" | ./node -p
  Hello World

Retry the send() syscall after a partial write.
