lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

auth: userdb passwd iteration now skips users not in first/last_valid_gid range Patch by Michal Hlavinka / Red Hat

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

auth: Moved cache_key from passdb_module to auth_passdb. This is in preparation for the next changeset, which moves default/override_fields also to auth_passdb.

auth: Use special AUTH_SUBSYS_DB/MECH parameters as auth_request_log*() subsystem. This avoids hardcoded strings all over the place and also allows assigning the correct passdb/userdb name for log messages generated by generic passdb/userdb code, which doesn't know exactly where it was called from.

auth: Added userdb result_success/failure/tempfail and skip settings, similar to passdb's.

auth: Use a common auth_request_log_unknown_user() for logging "unknown user" entries.

auth: userdb passwd iteration no longer skips shells. Some systems are using passwd for mail users with shell set to nologin. Maybe first_valid_uid check is good enough alone?

Oops :) Update copyrights to 2013 without breaking all .c files.

auth: userdb passwd lookups should have been done via worker processes by default.

Fixed compiling with OSes where NULL isn't defined as void pointer (e.g. Solaris).

Marked functions parameters that are allowed to be NULL. Some APIs were also changed. The non-obvious APIs where NULL parameter was changed to "" are master_service_init() and auth_master_user_list_init(). These checks can currently be enabled only on a patched clang: http://llvm.org/bugs/show_bug.cgi?id=6786
