Initial addition of tmpfs, an efficient memory file-system. This project was developed as part of Google's Summer of Code 2005 program. This change adds the kernel code, the mount_tmpfs utility, a regression test suite and does all other related changes to integrate these. The file-system is still *experimental*. Therefore, it is disabled by default in all kernels. However, as typically done, a commented-out entry is added in them to ease its setup. Note that I haven't commited the required mountd(8) changes to be able to export tmpfs file-systems because NFS support is still very unstable and because, before enabling it, I'd like to do some other changes. OK'ed by my project mentor, William Studenmund (wrstuden@).

Kill the tmpfs(9) manual page; it was just documenting internal details of tmpfs' "API" and was already rotting. Instead, merge all the relevant comments into the code. This includes acknowledgements to Google's Summer of Code 2005 program (they were in the AUTHORS section of tmpfs(9) before), so all the files need to be changed to include this sentence alongside the title. (Note that this was not a requirement of the program.)
