the lock_fd field of DiskPartition[64] is a file descriptor.
On Windows this is a HANDLE and on *nix platforms an int.
OpenAFS uses the FD_t type to provide platform specific type
info for file descriptors. Use it for the lock_fd field and
the salvageLock in ObtainsSalvageLock().
Finally, the on the wire diskPartition[64] struct in volser/volint.xg
also contains a lock_fd field. This is an on the wire field and
must be left at a fixed width of 32-bits. Since a file descriptor
is not portable across machines we truncate the 64-bit HANDLE value
to fit in the 32-bit lock_fd field when necessary.

GetHandler() sets up a fdset and returns the max socket fd
which is used with select(). Windows ignores the numfd param
(first param) of select() and therefore computing the max fd
value is meaningless. We can avoid a number of casts by
not attempting to treat this value as osi_socket.

Under certain demand salvage scenarios, it is possible for a stale header
to remain cached with the needsSalvaged flag asserted. Although this will
not affect clients accessing the volume over afsint, it is an issue for
volser clients. VAttachVolumeByName in volser will always attempt to pull
the header over FSSYNC before doing a disk read, under the assumption that
a cached entry in the fileserver will be more current than what is on
disk. This patch causes the fileserver to aggresively invalidate disk
header cache entries when a salvage is in-progress.

Add code signing with signtool.exe to the build process.
If all three of the required CODESIGN_xxxx environment
variables are defined, signtool will be used to sign each
exe, dll, and installer as they are built.
The three environment variables are:
CODESIGN_DESC = <description of application>
CODESIGN_TIMESTAMP = <url of certificate authority timestamp server>
CODESIGN_URL = <end user help URL>
The default signing certificate is the one that will be used by
signtool. If these environment variables are not defined, code
signing will be skipped.

patch based on work from shadow@dementia.org
the idea is to preclude multiple copies of a volume replica on a server,
as there's nothing to indicate which copy is correct and you can end up serving
stale data when you think you've just released and are serving something good

this will dump the current dafs vlru state on kill -XCPU (just as we dump other fileserver state)
that state is
VLRU is a garbage collection facility which automatically offlines
volumes in the background. The purpose of this facility is to
proactively offline infrequently used volumes to improve shutdown and
salvage times. The process of offlining a volume from the "attached"
state to the "pre-attached" state is called soft detachment.
VLRU works in a manner similar to a generational garbage collector.
There are five queues on which volumes can reside: new, intermediate,
old, held, and candidate:
held:
queue for volumes which are administratively barred from VLRU activity
candidate:
queue for volumes which have not been accessed recently, and are thus
candidates for soft detachment
new, intermediate, old:
generational queues for active volumes; state transitions controlled by
inactivity timers.
State transition timeouts are as follows:
candidate->new activity present
new->candidate (1*vlruthresh) minutes since last transition; no activity
new->mid (2*vlruthresh) minutes since last transition; activity
present
mid->old (4*vlruthresh) minutes since last transition; activity
present
old->mid (2*vlruthresh) minutes since last transition; no activity
mid->new (1*vlruthresh) minutes since last transition; no activity

* Vnode package concurrency model was overhauled. Unlike the old model,
where concurrency was controlled via reader/writer locks, the new model
uses a per-vnode finite state automata.
* add several new volume states to deal with volume vnode list operations
* a new FSSYNC command code was added to allow volume utilities to close
out a volume operation without causing the fileserver to mount the volume
* a new FSSYNC command code was added to allow volume utilities to
transition a volume into a hard error state
* the salvageserver has been modified to keep volume group partition
path data coherent with the fileserver (like many other parts of the
volume package, this code assumes all members of the group are stored on
the same vice partition)
* make salvageserver correctly handle volume state when a child worker
process terminates abnormally
* update volume pre-attachment code to deal with move volumes across
partitions on the same server
* add volume state sanity checks to more volume package interfaces
* original vos online patch introduced a race condition; rearchitect vos
online/offline to eliminate race condition, and reduce i/o load caused
by operation
* unify duplicate code in volserver related to servicing vos examine and
vos listvol requests
* add doxygen formatted comment blocks to numerous volume package elements
* various updates to fssync-debug to allow dumping vnode state, and
updates to deal with added volume and vnode states
* several 1.5-specific fixes related to fssync and salvsync

Some sites expect single-threaded volume attaches to happen in a specific
order. The parallel attach patch also changed the attach order for sites
not specifying -vattachpar.
When using the install-sh that ships with the source tree, Autoconf
substitutes in a relative path just to be annoying. Define the INSTALL
variables in each individual Makefile so that they find the proper file.
Remove the definitions from Makefile.config so that no one will
accidentally get the wrong ones.
Take advantage of the new platform infrastructure to move fs_conv_sol26 out
of the vol directory and remove the annoying Autoconf support for
optionally build it in favor of the platform support. We no longer care
about upgrading inode file servers on DUX, so make fs_conv_DUX4 go away.
Delete pinstall and convert the entire tree to use the install program
found by configure (falling back on install-sh in the local tree). This
means that we have to pre-create directories with install -d. Also redo
the install and dest rules to be lists of install rules rather than
dependencies driving separate make rules so that running make install will
always update the target directory with the current code, even if there are
files in the install area that are newer.
Stop installing libafssetpag; we're about to kill it in favor of a
different library. Remove some djgpp rules.
