FreeNAS Code

Add missing support for TARGET= in FreeBSD builds. This is a no-op for FreeBSD 8.x, but will be of some value in FreeBSD 9.x+.

Some shells (bash) consider it helpful to print out the current working directory when running in interactive mode, so let's force a fork with /bin/sh instead (yes, it's less efficient, but eventually I want this and other scripts to be executable 100% of the time in an interactive mode).

Don't use a dash to denote 'dirtiness' with git checkouts. This can mess up
our simplistic parsing scheme in common.system.get_sw_version, et all.

For the sake of consistency, change this to say x86/x64 instead of i386/amd64 to match what's going to be done on 8.0.3+ as this output is pretty blatant and I've gotten similar comments about branding before in the past from this section of code.

In classic Garrett style, I accidentally commented out a benign line. Let's uncomment it again.

Goodbye lighttpd!

(hello super secret python daemon modules... buwahaha)

Rebrand i386 as x86, amd64 as x64, following up on what's already being done in the FreeNAS 'legacy nightlies' by daoyama and zoon01.

This is a minimal change that changes just the branding in the image names because it would be far more invasive fixing the build system all the way up to speak x86 and x64.

Make lighttpd tunable and document that pcre is used by nginx.

Remove a redundant call ($ISODIR is already being removed in cleanup(..)).

Fix regression in r8998 where upgrades were failing because of a pathing change.

- s/data_new/data/ for the sake of being more intuitive.
- Use mkdir -p so that if the path already exists, things won't fail when running mkdir again (in theory.. there are some cases in practice where things will fail).
