npm: Upgrade to 1.3.19
npm: upgrade to 1.3.20

The 1.3.19 release had a critical bug: any packages published with it
could not be installed, because the shasum would be incorrect.

Thankfully, 1.3.19 was published using 1.3.19, so could not be installed
by any users!  However, if it goes out as part of a Node.js release,
then obviously that would be a problem.
npm: upgrade to 1.3.21
build: unix install node and dep library headers

Restores functionality from v0.8 where module authors may not be
relying on gyp for building their modules.
cluster, v8: fix --logfile=%p.log

The %p is replaced with the current PID.  This used to work in node.js
v0.9.7 but it seems to have been lost somewhere along the way.

This commit makes the fix from 6b713b52 ("cluster: make --prof work for
workers") work again.  Without it, all log data ends up in a single
file and is unusable because the addresses are all wrong.

docs: process.on('exit') receives exit code

The fact that the "exit" event passes the exit code as an argument
as omitted from the documentation. This adds the explanation and
augments the example code to show that.

doc: document that `process.send` is synchronous
