Comprehensive edit of Admin Guide chapter two (first 20%)

Administration) of the Administration Guide for current AFS and current
computing concepts.
Remove references to an AFS-provided login utility and discuss local login
configuration for Kerberos more generically. Further clarify the role of
ssh in ensuring the user has access to files in AFS during remote login.
Improve the inode and namei discussion slightly. Update the setuid
discussion for the new default of disabling setuid for cells and for the
known security flaws in enabling setuid. Modernize terminology for DNS
around cell naming and remove the descriptions of TLDs. We can now assume
our target audience knows this stuff.
Move index terms into the appropriate section for what's being indexed in
a few more cases.
Lots of other, more minor wording changes and updates.
this code makes us work in the face of a sub1500 mtu network.

to grow the mtu must be scheduled so we aren't forced to heavily
brute-force on failure to discover the exact mtu immediately;
for performance, we do want to grow to the real mtu.

Windows: Support building a lite-client installer
If LITECLIENT is defined when invoking the WiX based MSI installer
build, we will build a light-weight client installer MSI. This
minimizes the size of the installer for users who only need client
functionality from OpenAFS.
The light-weight client excludes:
- Server components
- Control center components
- Administration utilities
- Debug symbols
Lite-client installer can also be built by invoking target wix-lite
from the root NTMakefile.
"fs checkservers" during cache creation can crash client
Many pioctl calls pass as soon as the afs_resourceinit_flag is set,
which happens relatively early, alas before the cell name is set.
PCheckServers and others need the latter and dereference NULL.
Easiest: set the cell name as soon as it is known and the dynroot initialisation
piggy-backed to it can be done.

Solaris: stop NetIfPoller on shutdown
The NetIfPoller code that is enabled on AFS_SUN510_ENV never gets
shutdown properly. The current code looks as if it was intended for
NetIfPoller to recognize the appropriate termState and just return,
but we never wait for it, and so we can complete the shutdown sequence
without NetIfPoller ever knowing that we are shutting down. This can
cause the machine to panic, as we keep attempting to run NetIfPoller
even after libafs has been unloaded.
Since NetIfPoller is fired by default every 30 seconds, we probably do
not want to wait for it to fire during shutdown. Instead, just destroy
the necessary timeout and task queue, which will wait for NetIfPoller
to complete if running, and will just prevent it from running in the
future otherwise.

Windows: move afsconfig.h / param.h to afscred.h
move the inclusion of afsconfig.h and param.h to
afscred.h so that they are included everywhere
and so that the conditional use of _USE_32BIT_TIME_T
is applied consistently by afscred.h.
