Revert "afs: Use 64-bit inode numbers"
This reverts commit e1e008338639d6cc0d836ff8079e6fb42021ab9e. Using
64-bit inode numbers can make AFS largely inaccessible to 32-bit
programs that are not compiled with large file support, since the
inode number we provide is not representable in a 32-bit struct stat.
Using 64-bit inode numbers thus can break quite a few programs, and
has little benefit, so don't do it.

libafs: switch to hardcoded source names with CRULE
Most of the userspace tree uses AFS_CCRULE for how to compile
things. We cannot use this directly for libafs, since in the
general case kernel and userland code may need to be treated
with an entirely different compiler and compiler options.
Switching libafs fully to a (e.g.) LIBAFS_CCRULE would be a substantial
amount of work, and require a lot of testing. However, we can
stop passing -c $? (the out-of-date sources) in CRULE_{NO,}OPT
and add the source file after each invocation of the CRULEs,
an incremental step towards LIBAFS_CCRULE.
This has the extra advantage of not causing issues when integrating
with kernel module build systems that automatically add dependencies
to all object file targets. (In such cases, $? expands to multiple files
and 'gcc -o foo.o -c' bails out.)
Most of this change was automatically generated from the following
awk script:
==========
/[a-zA-Z_0-9].o:/ {path=$2;}
/^ \$\(CRULE_/ {print $0,path;}
!/^ \$\(CRULE_/ {print;}

received by the SMB Redirector. OpenAFS failed to properly specify
a Challenge and DomainName in the response when the security mode
is SMB_AUTH_NONE (or share with password). This patchset corrects
smb_ReceiveNegotiate() so that it adheres to the protocol specification.
Revert "Rx: When call receive is done, send ack all packet"
This reverts commit 3cd3715e608b801b4848399e42cb47464e6e3cc3,
which replaces an ack with an ackall; ackall processing does
not actually mark all packets acked when it is received, so
it is insufficient.
