6c9c0b52b8 [PATCH] largefile support for accounting
There is a problem in the accounting subsystem in the kernel can not
correctly handle files larger than 2GB.  The output file containing the
process accounting data can grow very large if the system is large enough
and active enough.  If the 2GB limit is reached, then the system simply
stops storing process accounting data.

Another annoying problem is that once the system reaches this 2GB limit,
then every process which exits will receive a signal, SIGXFSZ.  This signal
is generated because an attempt was made to write beyond the limit for the
file descriptor.  This signal makes it look like every process has exited
due to a signal, when in fact, they have not.

The solution is to add the O_LARGEFILE flag to the list of flags used to
open the accounting file.  The rest of the accounting support is already
largefile safe.

The changes were tested by constructing a large file (just short of 2GB),
enabling accounting, and then running enough commands to cause the
accounting data generated to increase the size of the file to 2GB.  Without
the changes, the file grows to 2GB and the last command run in the test
script appears to exit due a signal when it has not.  With the changes,
things work as expected and quietly.

There are some user level changes required so that it can deal with
largefiles, but those are being handled separately.

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!
