1. using smbc_getxattr() et al, one may now request all access control
entities in the ACL without getting all other NT attributes.
2. added the ability to exclude specified attributes from the result set
provided by smbc_getxattr() et al, when requesting all attributes,
all NT attributes, or all DOS attributes.
3. eliminated all compiler warnings, including when --enable-developer
compiler flags are in use. removed -Wcast-qual flag from list, as that
is specifically to force warnings in the case of casting away qualifiers.
Note: In the process of eliminating compiler warnings, a few nasties were
discovered. In the file libads/sasl.c, PRIVATE kerberos interfaces
are being used; and in libsmb/clikrb5.c, both PRIAVE and DEPRECATED
kerberos interfaces are being used. Someone who knows kerberos
should look at these and determine if there is an alternate method
of accomplishing the task.
