This removes a structure field which turned out to be pointless, and
references to it.

This patch makes a bunch of non-functional changes -
return(foo); becomes return foo;
some statements are broken across lines for readability
some trailing whitespace is cleaned up
open_one_chan took four arguments, three of which could be
deduced from the first. Accordingly, they were eliminated.
some examples of "} else {" had a newline added
some whitespace cleanup in the indentation
lines_init got some control flow cleanup
some long lines were broken
removed another emacs-specific C formatting comment

failure
User get *a lot* confused when consoles don't work but we don't report
anything. And, as reported in the comment, using printk to report "your
console doesn't work" isn't likely to go that far.
Fix the problem on the base of this: stack consumption by host printf(). Use
kernel sprintf() and os_write_file, using a wild guess that one page will be
enough for the message, to preallocate the buffer with kmalloc().

setup_initial_poll is only called with sigio_lock() held, so use appropriate
allocation.
Also, parse_chan() can also be called when holding a spinlock (see line_open()
-> parse_chan_pair()).
I have sporadic problems (spinlock taken twice, with spinlock debugging on UP)
which could be caused by a sequence like "take spinlock, alloc and go to
sleep, take again the spinlock in the other thread".

From: Al Viro - we have error messages with KERN_ERR in them, so they
should be printk-ed rather than printf-ed.

Fix some console locking problems (including scheduling in atomic) and various
reorderings and cleanup in that code. Not yet ready for 2.6.12 probably.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
