FreeNAS Code

Fix bug in presenting login version.

lets use str instead of unicode for smtplib.login as it seems to be the root cause for the
"TypeError: character mapping must return integer, None or unicode" exception

Fix a potential corner case where the version would print out the $REVISION variable in parentheses (this mostly applies to release builds); see nanobsd/freenas-common:save_build() for more details about what I mean.

Squawk less like FreeNAS in syslog and more like the component that's being squawked from.

Cache the version to avoid unnecessary 'I/O' (even though it's just a memory disk).

Clean up 'find alias for smtplib' script:

1. Unbreak multiple recipient specification on the command line.
2. Make it apparent that -t actually is for parsing recipients from a message
body.
3. Use the email module with some minimal parsing to avoid unnecessary breakage
down the line because of ad hoc header parsing method previously employed.
4. Make send_mail a bit more robust / atomic.
5. Don't override library modules (email).
6. Remove dupe modules.
7. Simplify code a bit more (it could be simplified even further, but this is
good enough for now).

This will fix mass emailing, which affects SMART reports at least if multiple
recipients are specified.

This addresses ticket # 960.
