rx: Don't have 2 different protos for rxi_CheckCall

Use a single prototype for rxi_CheckCall in both the pthread and
lwp cases. Remove the #ifdef maze at the call sites, and take advantage
of the fact that MUTEX_EXIT reduces to an empty string in the lwp
case.

rx: Don't double check conn->call

We currently have

call = conn->call[channel]
if (call) {
   ...
} else {
    call = conn->call[channel]
    if (call) {
       ...
    }
}

As we don't drop (or acquire) any locks between the first and the
second check of call, there's no way that the result can be different
from the first time we checked. So just get rid of the uneccessary
code, and reindent the following block to match.

rx: Make lock-free call data explicit

For speed, the application thread accesses a number of elements of
the call structure without holding the call lock. This is safe, as
long as the application thread is the only place in which these
items of data are accessed.

Make this distinction explicit by creating a new structure to hold
all of these fields, and include this structure within the rx_call.

This turns up one place in the code (SendXmitList) which accesses an
application private piece of data in the listener and event threads.
A forthcoming patch will fix this.

Unfortunately the test for the end of the VLRU scan is incorrect

and any code that is conditional on defersleep=1 was never

The fuse tests are fundamentally broken as they stand:

*) They rely on files that have not been committed to the tree. To
   function correctly the file fuse/conf/CellServDB must be present
*) They always run, regardless of whether the fuse helper binaries are
   installed on the developers system, or even on whether the tree was
   built with fuse support enabled.
*) They pass, even if fuse fails to start up
*) The file fuse.sh is committed, despite being unused. This is
   particularly confusing, as it looks like this is where the tests
   are performed from (its not, testing is done in dynroot-t)
*) fuse-log should be either cleaned up, or flagged as ignored in
   .gitignore

Revert the commit until such time as all these issues can be fixed

sys: Split up syscall.lo 'echo's

Currently we echo a string to syscall.lo to generate it. However,
'echo' is often a shell builtin, and some shells (such as bash) do not
interpret escape codes like \n unless the -e option is given. So, this
results in syscall.lo containing a single commented line, which
results in .libs/libafsrpc_sys.a not getting created, which later on
causes errors.

Instead, just split the syscall.lo generation into separate echo
invocations, to make sure we work everywhere.

RedHat: Avoid the DKMS escaping silliness

Depending on the version of DKMS, the current MAKE[0] variable in the
dkms.conf needs different numbers of backslashes. Commit 81a9a33e
tried to address this by changing the contents of dkms.conf depending
on whether or not we were on Fedora. However, the change occurred in
DKMS 2.2, so if someone running RHEL tries to use a newer DKMS, this
will fail.

So instead of trying to guess at the level of escaping we need, just
avoid needing to escape anything with backslashes. We can quote the
heredoc marker to avoid variable expansion inside the heredoc, we can
use a case statement instead of using backticks and local variables
and such, and we can use single quotes for the outer MAKE assignment.
With this, we should not need any backslashes when writing dkms.conf,
so we should work with any DKMS version.
