The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Moreover, as a result of that change we may invoke a DSO's atexit handler after it has been unmapped.

Given that it is already in FreeBSD's libc it is useful for the cases where reallocation involves a multiplication.

Replace it with a nesting depth counter so it only blocks one level (the first is the group -> group_compat translation, the second is the actual backend). This is one of two bugs that break getgrouplist() in the compat case, the second being that the backend's own getgroupmembership() method is ignored. Unfortunately, that is not easily fixable without a redesign of our nss implementation (which is also needed to implement the +@group syntax in /etc/passwd).

As a side effect, this fixes a race condition which can occur if multiple threads call nsdispatch(3) concurrently before nsswitch.conf has been parsed. Previously, the thread holding conf_lock could cause other threads to return from nss_configure() before nsswitch.conf had been parsed, forcing them to fall back to the default sources for their NSS methods.
