    Retire "pwcheck" expansion condition

appears to remove too much

...
cc -Wno-parentheses -Wno-dangling-else version.c
cc -Wno-parentheses -Wno-dangling-else -o exim
ld: error: undefined symbol: auth_call_saslauthd
>>> referenced by expand.c
>>>               expand.o:(eval_condition)
cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** Error code 1

Stop.

call_pwcheck.c is removed in its entirety but contains:

-/*************************************************
-*       External entry point for pwauthd         *
-*************************************************/
-
-/* This function calls the "saslauthd" Cyrus-SASL authentication daemon,
-saslauthd, As this is called from the string expander, all the strings will
-always be in dynamic store and can be overwritten.
-
-Arguments:
-  username        username
-  password        password
-  service         optional service
-  realm           optional realm
-  errptr          where to point an error message
-
-Returns:   OK if authentication succeeded
-           FAIL if authentication failed
-           ERROR some other error condition
-*/
-
-int
-auth_call_saslauthd(const uschar *username, const uschar *password,
-  const uschar *service, const uschar *realm, uschar **errptr)

unless I misunderstood, the intention was to remove support for pwcheck and not
saslauthd.
