stream_wrap: don't call Number::New()

Replace call to Number::New() with a call to Integer::NewFromUnsigned().

Profiling a Real World(TM) application with perf(1) suggests that the
conversion of its argument from integer to double is disproportionally
costly: over 60% of CPU cycles accountable to WriteStringImpl() are
attributable to the conversion.

After changing it to Integer::NewFromUnsigned(), WriteStringImpl()
has dropped from the 'most costly functions' top ten altogether.

build: include postmortem symbols on linux

Previously we were building the symbols, but the linker was garbage
collecting the symbols because they weren't used. Inform the linker
that we want to keep all symbols from v8 around.

tls: reset NPN callbacks after SNI

SNI callback selects a new SSL_CTX for the connection, which doesn't
have NPN callbacks set up.

process: document kill(0), disallow kill(O_RDWR)

The null signal test existed, but only tested the case where the target
process existed, not when it did not exist.

Also clarified that SIGUSR1 is reserved by Node.js only for receiveing,
its not at all reserved when sending a signal with kill().

kill(pid, 'O_RDWR'), or any other node constant, "worked". I fixed this
by also checking for 'SIG'. The same as done in the isSignal() function.
Now the signal names supported by process.kill() are the same as those
supported by process.on().

tls: fix pool usage race

When calling `encOut` in loop, `maybeInitFinished()` may invoke
`clearOut`'s loop, leading to the writing of interleaved data
(encrypted and cleartext) into the one shared pool.

Move `maybeInitFinished()` out of the loop and add assertion for
future.

crypto: Make Decipher._flush() emit errors.

When Decipher processes a stream using an incorrect key, the
DecipherFinal() method throws an unhandled exception at the end of the
stream.
lib: child_process spawn handle ENOENT correctly

child_process spawn wasn't handlig ENOENT correctly on Windows.
This is half a fix for test-child-process-cwd.js.
The other half is going into libuv.
build: add libicu i18n support

Adds a --with-icu-path= switch to the configure script.  Requires that
the user checks out the copy of libicu that's bundled with chromium to
a fixed directory.  It's still a little rough around the edges but it
works.

Fixes #6371.
tls: fix handling of asterisk in SNI context

Wildcard server names should not match subdomains.

Quote from RFC2818:

   ...Names may contain the wildcard
   character * which is considered to match any single domain name
   component or component fragment. E.g., *.a.com matches foo.a.com but
   not bar.foo.a.com. f*.com matches foo.com but not bar.com.
