NetBSD-SoC: Implement Ext3 file system support

What is it?

The aim of the project is to provide ext3 support on NetBSD. At this time NetBSD supports only ext2 or ext3 with a clean journal, so in principle the focus of the project is to provide journaling support for ext2.

Status

I have created a blog for people interested in my activity on this project and it's located at http://alinrus.wordpress.com I'll start blogging as soon as possible.

_April 21, 2008: Community Bonding Period -- Students get to know mentors, read documentation, get up to speed to begin working on their projects.
May 26, 2008: Students begin coding for their GSoC projects; Google begins issuing initial student payments
July 7, 2008: Mentors and students can begin submitting mid-term evaluations.
July 14, 2008: Mid-term evaluation deadline; Google begins issuing mid-term student payments provided passing student survey is on file.
August 11, 2008: Suggested 'pencils down' date. Take a week to scrub code, write tests, improve documentation, etc.
August 18, 2008: Firm 'pencils down' date. Mentors, students and organization administrators can begin submitting final evaluations to Google.
September 1, 2008: Final evaluation deadline; Google begins issuing student and mentoring organization payments provided forms and evaluations are on file.

Deliverables

Mandatory (must-have) components:

mount_ext3
fsck_ext3
newfs_ext3fs
journaling metadata and/or file data
compliance with the Linux journal

Optional (would-be-nice) components:

online resizing would be nice

Technical Details

As you may assume at this point the implementation will be based on the existing Wasabi Write-Ahead Physical Block Logging more on the blog shortly
