r2436: the second big lump of posix vfs code. this is still just a skeleton, and many of the functions are just based on the simple vfs backend, they are there to allow me to run smbtorture tests against the real parts of the posix backend. (This used to be commit f2fa7fe565e89360dba3bb5434d3a6a36f398348)

r2561: completely redid the ntvfs module chaining code, You can now do something like: ntvfs handler = nbench posix and the nbench pass-thru module will be called before the posix module. The chaining logic is now much saner, and less racy, with each level in the chain getting its own private pointer rather than relying on save/restore logic in the pass-thru module. The only pass-thru module we have at the moment is the nbench one (which records all traffic in a nbench compatibe format), but I plan on soon writing a "unixuid" pass-thru module that will implement the setegid()/setgroups()/seteuid() logic for standard posix uid handling. This separation of the posix backend from the uid handling should simplify the code, and make development easier. I also modified the nbench module so it can do multiple chaining, so if you want to you can do: ntvfs module = nbench nbench posix and it will save 2 copies of the log file in /tmp. This is really only useful for testing at the moment until we have more than one pass-thru module. (This used to be commit f84c0af35cb54c8fdc4933afefc18fa4c062aae4)
