Subject: [nodejs] nodejs 0.10.12 and Angstrom issues

This reverts commit acbdabb.

Avoids alignment issues (unaligned loads/stores) on ARM. Originally
added in commit 285d8c6.

Fixes #3030.

This is a back-port of commit c9644fb from the master branch.

This is a back-port of commit e945903 from the master branch.

There was previously up to a second exit delay when exiting node
right after an http request/response, due to the utcDate() function
doing a setTimeout to update the cached date/time.

Fixing this should increase the performance of our http tests.

Assert that when the client closes it has seen an error, this prevents
the test from timing out.

Also queue a second write in the case that we were able to send the
buffer before the other side closed the connection.

UsingDomains() assigned process_tickCallback when it had already
been set by MakeCallback() a few frames down the call stack.

Dispose the handle first or we'll retain whatever is in the lexical
closure of the old process._tickCallback function.

Fixes #5795.
