Add file system persistence tests:
Change Make.tests to invoke pintos a second time for the extended
filesys tests, and in that run to tar up the file system contents and
copy it out.
Update grading scripts to check the generated tarballs.
Update documentation.
Update documented requirements for remove() of a directory to give
basically the options offered by POSIX, and update the tests to check
for these behaviors.
Remove dir-lsdir test, which no longer made sense given that readdir
is used so heavily in other tests.
Merge dir-mk-vine and dir-rm-vine tests into a single dir-vine test,
which is now much more stringent.
Merge dir-rm-cwd-cd and dir-rm-cwd into a single dir-rm-cwd test,
which is now much more stringent.
Check that a non-empty directory cannot be removed.

File system project updates:
Require support for . and ...
Add inumber system call, so getcwd can be implemented,
and inode_get_inumber() function.
Implement these features in the reference solution.
Add "pwd" example program and require explanation of it in design
document.
Implement "cd" in shell.
Add -l option to "ls" example program.
Describe interpretation of unusual file names.
Remove filesys_self_test().
Update TODO.

Replace lsdir system call by readdir, isdir system calls,
which are far less offensive to good taste.
Add dir_get_inode() and dir_readdir() functions.
Remove dir_list(), filesys_list(). The latter was unused.
Update project documentation, solutions, and tests.
Rewrite "ls" example program to use the new interface, and add the
ability to specify a directory name and a "long format" feature.
Add "cd" command to shell.

Major revisions to documentation.
Rewrite VM assignment entirely, adding implementation order and
terminology suggested by Godmar Back.
Make the terminology used elsewhere agree.
Rename "Tour" to "Reference Guide" and move to appendix.
Add "Virtual Addresses" and "Page Tables" sections to reference guide.
Rename "References" to "Bibliography" (to avoid confusion) and move to
end of documentation.
Get rid of option to eagerly load partial pages.
Get rid of fullpage.lds linker script, so rename the normal one from
normal.lds to user.lds.
Break mmu.h into vaddr.h and pte.h.
Add "mcat" to examples as a simpler example of mmap.
NB: Any webpages that reference chapters in the documentation will
need to be updated, because the chapters have been reordered.

Invert the priority scheme, so that PRI_MIN is now the lowest priority
and PRI_MAX is now the highest priority. This should reduce student
confusion (and at the same time subtly frustrate attempts to resubmit
work from previous quarters).

The lock functions don't really need to disable interrupts themselves,
since they're protected by the semaphore.
Thanks to Godmar Back for reporting this.

his sample GDB debugging sessions.
Talk about pintos-gdb.
Talk about debugging triple faults with the Bochs triple-fault patch.
