redhat: Don't replace modified configuration files during rpm update

The previous setting for three %config files mentioned in the spec file:

%config /etc/sysconfig/openafs
%config %{_prefix}/vice/etc/ThisCell
%config %{_prefix}/vice/etc/cacheinfo

When using an unadorned %config, it's possible that these files will
be replaced by the packaged version during a package update.  Changing
%config to %config(noreplace) means that the packaged file will be
installed with the extension .rpmnew if there is already a modified
(from the existing package's version) file with the same name on the
installed machine.

The concern here is that updating an existing system could potentially
change the configuration if the person installing doesn't pay close
attention.  The Rule of Least Surprise indicates that we should
try to preserve existing configuration changes whenever possible.

Commit e445faa68c5ec6e47d3fd9d7318ade71d98703a9 unintentionally
failed to acquire the call->lock prior to RXS_PreparePacket being

afs: Never #define away afsd_dynamic_vcaches

Some versions of the Solaris Studio compiler on SPARC (at least 12.2
and possibly others, but not 12.3) get a little confused by code like
this:

    extern int foo;
    int
    somefunc(void) {
        if (0) return foo;
        return 0;
    }

When optimization is turned off, this results in an undefined symbol
reference to 'foo' (which is normal), but the resulting object file
lacks a relocation entry for the symbol 'foo', so the symbol remains
undefined after linking. In the OpenAFS tree, this occurs in
afs_daemons.c which references afs_vcount and afs_cacheStats in this
manner due to afsd_dynamic_vcaches being defined as '0' on Solaris.
The end result is that the libafs kernel module is not loadable, since
it complains about afs_vcount and afs_cacheStats being undefined, even
though the symbol definitions are also in the module.

While this is a bug in Solaris Studio and has since been fixed, it is
simple to work around this so we are usable with more compilers. If we
just always declare afsd_dynamic_vcaches as a regular variable, it
works around this issue and keeps the code a tiny bit simpler. So, do
that.

Windows: Client handling of VNOSERVICE

VNOSERVICE should not be grouped together with the volume status
error codes.  It is used to indicate that the RPC was not serviced.
The file server issues it when its idle dead timeout period is reached
while receiving rx call data.  The client's existing status information
is still valid and the client can retry the call.

LINUX: move afs_notify_change to osi_vnodeops.c

afs_notify_change is almost always used solely in inode_operations
structs, and is more similar to the other per-vnode functions. Put it
with the other per-vnode functions for better organization, and so
they can use the same static functions.

Move the helper functions iattr2vattr and vattr2inode along with it.

LINUX: Use afs_convert_code in afs_notify_change

afs_notify_change currently just returns "-code". This can cause a
panic if the error code is negative, since we will return a positive
error code, which may get interpreted as a valid pointer value in
higher levels.

Specifically, if we hit afs_notify_change via something like this code
path:

do_sys_open -> do_filp_open -> open_namei -> may_open -> do_truncate
-> notify_change -> afs_notify_change (via inode->i_op->setattr)

the positive error value will be interpreted by do_sys_open as a valid
'struct file' pointer, and will be dereferenced.

So pass the return value through afs_convert_code, like all of the
other vnode ops, so we ensure we return an error properly.

viced: Do not ignore all InlineBulkStatus errors

InlineBulkStatus currently returns 0 unconditionally, no matter what
errors are encountered. If we encounter an error early enough, from
CallPreamble for example, we do not fill in the OutStats nor CallBacks
structures at all. Since we return success anyway, this results in the
client getting AFSFetchStatus structures full of zeroes (or garbage,
before commit 726e1e13ff93e2cc1ac21964dc8d906869e64406).

Since current OpenAFS clients do not perform any sanity checks on the
information received, this can result in cache corruption of files
being seen incorrectly as empty, and, before commit 726e1e, more
arbitrary corruption.

So instead, return an error if we encounter an error before we iterate
over the given FIDs. We still of course do not return an error for any
errors encountered during the actual metadata retrieval, as those are
reflected in the individual per-fid status structures.
