libbsdconf: parse from a bounded in-memory bufferHEADmain

Copy the descriptor into a buffer of at most 64 MiB (raise it with
BSDCONF_MAX_BYTES) and tokenize with bsdconf_scan(), the walker
bsdconf_put() already uses.  Input above the cap fails with EFBIG.
Bump libbsdconf to 1.2.0 and sysconf(8) to 2.0.
