AFS redirector timestamp handling does not support this behavior.

write operation even after -1 is set via the file handle.
This patchset implements the -1 behavior for LastWrite. It also follows
the standard Windows practice of setting the LastWrite timestamp to be the
time of close of the handle that performed the write, not the time of the
write itself.
Finally, it should be noted that since RX*FS_StoreXXX operations update
the last write time on the server the client must restore the LastWrite

Fix rx_EndCall error precedence
Callers of rx_EndCall in various parts of the code handle errors a bit
differently from each other. The correct way to use rx_EndCall is
almost always some form of:
code = rx_EndCall(call, code);
This will cause the call to abort with 'code' if the call is not
already aborted, and will return the abort code for the call (or 0 if
the call ended successfully). It is thus impossible for 'code' to
start out with a non-zero value in the code snippet above, and end up
with a value of 0 after the code snippet.
Most code follows this pattern, because this is how the
rxgen-generated client RPC wrappers are written. So for any non-split
Rx call, this is how the error precedence works.
However, some code (mostly for Rx split calls), needs to handle
calling rx_EndCall itself, and some code appears to think it is
possible for rx_EndCall to return 0 when we already had a non-zero
error. Such code tries to ensure that we don't ignore an error we
already got by doing something like this:
However, this is not correct. If a call gets killed with an abort code
partway through executing an RPC, and the client tries to end the RPC
with e.g. EndRXAFS_FetchData, the client will get an error code of
-451 (RXGEN_CC_UNMARSHAL). The actual error code is in the abort code
for the call, but with the above 'code2' snippet, we can easily return
an error of -451 instead, which will usually get interpreted as some
unknown network-related error.
This can manifest as a problem in the unix client, where if a
FetchData call fails due to, for example, an "idle dead" timeout, we
should result with an error code of RX_CALL_TIMEOUT. But because of
the above issue, we'll instead yield an error of -451, causing the
server to be marked down with the following message:
afs: Lost contact with file server ... (code -451) ...
So, fix most rx_EndCall callers to follow the 'code = rx_EndCall(call,
code);' pattern. Not all of the changes here are to "wrong" code, but
try to make all of the rx_EndCall call sites look more consistent.
There are a few exceptions to this pattern, which warrant some
variations:
- A few instances in src/WINNT/afsd/cm_dcache.c do seem to want to
record the original error before we ran rx_EndCall, instead of
seeing the rx abort code. We still return the rx_EndCall-returned
value to the caller, though.
- Any caller of RXAFS_FetchData* needs to read a 'length' raw from
the rx split stream. If this fails, we need to abort the call, but
we don't really have an error code to give to rx_EndCall. Failure
to read a length indicates that the server is not following
protocol properly, so give rx_EndCall RX_PROTOCOL_ERROR in these
instances. The call should already be aborted by this point, so
most of the time this code will be ignored; it will only make a
difference if the server tries to end the call successfully without
sending a length, which is indeed a protocol error.
- Some Rx clients can encounter a local error they don't want to send
to the server via an abort, so they just end the call successfully,
and only use the rx abort code if they don't already have a local
error. This is in a few places like src/butc/dump.c and
src/volser/vsprocs.c.
- Several places don't care what the error from rx_EndCall is, such
as various call sites in server-side code.
The behavior of the Windows client w.r.t rx_EndCall was changed a bit
into its current behavior in commit a50fa631cad6919d15721ac2c234ebbdda2b4031 (ticket 125018), which just
appears to be wrong. This was partially reverted by commit ae7ef5f5b963a5c8ce4110a7352e0010cb6cdbc1 (ticket 125351), but some of
the other call sites were unchanged. The Unix client appears to have
been doing this incorrectly for at least FetchData calls since OpenAFS
1.0.
To make it hopefully more clear that rx_EndCall cannot return 0 if
given a non-zero error code, add an assert to rx_EndCall that asserts
that fact.

volinfo: separate volscan binary
Refactor vol-info.c into several files and change the makefile to
build a separate volscan binary, instead of using the program name
to determine if the user is running volinfo or volscan.
This commit adds new source files for the volinfo and volscan main()
function and a common header file.

pioctl.c: removed unused variable
The 'rval' variable is only actually used in the LINUX20 case;
adding another conditional block is making the LINUX20 case
different enough that it should get split out entirely.
Doing so lets the 'else' clause be simpler.
Found by clang on FreeBSD 10.0.

fs: display cell not available on ESRCH
The cache manager pioctls abuse ESRCH to represent errors due to
unavailable cell information. Give a more sensible error message to
the user when a pioctl returns an ESRCH error, instead of "no such
process", which is the conventional meaning of ESRCH.
The new error message is consistent with the Windows implementation
of fs.
For example, on a host with a misconfigured ThisCell and/or CellServDB.

Linux: Do drop dentry if lookup returns ENOENT
Commit 997f7fce437787a45ae0584beaae43affbd37cce switched to using
d_invalidate instead of d_drop to prevent unhashing dentries
which are only temporarily invalid and may still be referenced
by someone having a current working directory pointing to it.
This could result in getting ENOENT from getcwd() after some
transient problems, even when the directory is there and
accessible.
The change had the side effect of potentially leaving something
visible when it has actually been removed, for instance a mountpoint
removed by "fs rm".
If afs_lookup returns ENOENT, we want to forcibly drop (unhash)
the dentry, even if it has current users.

vos: GetServer search for non-loopback address
GetServer() is used to obtain an IP address for the 'aname' parameter.
'aname' can be either a dotted address or a host name. If it is a dotted
address, it is returned immediately. If it is a host name, then
gethostbyname() is used to obtain an IP address.
The prior version of this function had two failings:
1. It assumed that a struct hostent only contained a single address.
It used the former h_addr field. For all platforms supported by
OpenAFS h_addr is a macro referencing the first address in the
h_addr_list array. If h_addr was a loopback address, it would
ignore any additional addresses that might be in the list.
2. It assumed that if gethostbyname(aname) returned a loopback
address as h_addr that 'aname' must be referring to the machine
that the vos command is being executed on. It therefore used
gethostname() to obtain an alternate name to use for a gethostbyname()
query. The results of this query were not checked to be a loopback.
As a result, a loopback address could be returned to the caller which
in turn could be set into the VLDB.

libafs: reset global icl set pointers on shutdown
Avoid panicking when an icl tracing function is called after
shutdown_icl.
There is a window during shutdown in which pioctls can be requested
after the shutdown_icl is issued. Reset the global icl set pointers
so tracing is disabled after the shutdown_icl, instead of using
pointers to freed memory.
Removed the unneeded afs_icl_FindSet calls and use the global
pointers which were set during the initialization.

(1) remove -mlong-branch from amd64 build
Random internet postings suggest that it has triggered a warning
since at least Xcode 3.2, and the gcc manual page suggests that
it is only applicable on ppc, anyway.
(2) remove -mpreferred-stack-boundary=4 from the amd64 build
The evidence here shows up less readily in an internet search,
but it seems that Apple's compilers will force the stack alignment
to 16 bytes regardless of what is passed here. One poster had
trouble with -mpreferred-stack-boundary being unused in Xcode 4.4.1
This change only fixes warnings reported as errors by buildbot; it
does not attempt to fully synchronize with the flags that Xcode 5.1
uses for kernel module builds.
