Add SPDX-License-Identifier to files.
Newer compilers define __BYTE_ORDER__ and __ORDER_{BIG,LITTLE}_ENDIAN__ Also add riscv the little endian list.
Rename __dso_public -> sudo_dso_public and move to config.h.
Apply Google inclusive language guidelines. Also replace backwards with backward.
Add NSS_TRYAGAIN and correct buflen in struct nss_XbyY_buf_t. Add some function argument names. Also use struct nss_db_state * instead of void * in nss_db_root_t. We don't define struct nss_db_state but since it is a pointer all we need is a forward declaration.
Avoid using a leading underbar in defines as they are reserved in ISO C.
