Init functions in winbind idmap modules

[Christof Schmitt]

The init functions in the winbind idmap modules are not very consistent,
some are called samba_init_module, others use different names:

source3/winbindd/idmap_ad.c:NTSTATUS samba_init_module(void)
source3/winbindd/idmap_autorid.c:NTSTATUS samba_init_module(void)
source3/winbindd/idmap_ldap.c:NTSTATUS idmap_ldap_init(void)
source3/winbindd/idmap_nss.c:NTSTATUS idmap_nss_init(void)
source3/winbindd/idmap_passdb.c:NTSTATUS idmap_passdb_init(void)
source3/winbindd/idmap_rfc2307.c:NTSTATUS idmap_rfc2307_init(void)
source3/winbindd/idmap_rid.c:NTSTATUS samba_init_module(void)

I also saw that there is some code in waf to create a define to
samba_init_module, but i find that somewhat confusing.

Should all modules use a similar init function name for consistency?
