nid: Fix infinite loops when system calls fail [#645]
There were three loops in nodeinit.c that could potentially become
infinite
if a system call returns -1. It is fine to try again when e.g. errno ==
EINTR, since that is a temporary error that will go away eventually. In
general however, trying again will not make the error go away and the
loop
would become infinite. Also made a file descriptor non-blocking to avoid
blocking indefinitely in read().

Reviewer Checklist:
-------------------
[Submitters: make sure that your review doesn't trigger any checkmarks!]
Your checkin has not passed review because (see checked entries):
___ Your RR template is generally incomplete; it has too many blank entries
that need proper data filled in.
___ You have failed to nominate the proper persons for review and push.
___ Your patches do not have proper short+long header
___ You have grammar/spelling in your header that is unacceptable.
___ You have exceeded a sensible line length in your headers/comments/text.
___ You have failed to put in a proper Trac Ticket # into your commits.
___ You have incorrectly put/left internal data in your comments/files
(i.e. internal bug tracking tool IDs, product names etc)
___ You have not given any evidence of testing beyond basic build tests.
Demonstrate some level of runtime or other sanity testing.
___ You have ^M present in some of your files. These have to be removed.
___ You have needlessly changed whitespace or added whitespace crimes
like trailing spaces, or spaces before tabs.
___ You have mixed real technical changes with whitespace and other
cosmetic code cleanup changes. These have to be separate commits.
___ You need to refactor your submission into logical chunks; there is
too much content into a single commit.
___ You have extraneous garbage in your review (merge commits etc)
___ You have giant attachments which should never have been sent;
Instead you should place your content in a public tree to be pulled.
___ You have too many commits attached to an e-mail; resend as threaded
commits, or place in a public tree for a pull.
___ You have resent this content multiple times without a clear indication
of what has changed between each re-send.
___ You have failed to adequately and individually address all of the
comments and change requests that were proposed in the initial review.
___ You have a misconfigured ~/.hgrc file (i.e. username, email etc)
___ Your computer have a badly configured date and time; confusing the
the threaded patch review.
___ Your changes affect IPC mechanism, and you don't present any results
for in-service upgradability test.
___ Your changes affect user manual and documentation, your patch series
do not contain the patch that updates the Doxygen manual.
