Back-port commit 16fbac39f into 9.3 and 9.2, so that these
out-of-support branches can be built with clang without wading
through a pile of warnings about strlcpy and related functions.
check_decls.m4 required some adaptation to work with autoconf 2.63,
but nothing too major.

RELSEG_SIZE * BLCKSZ must be less than your OS' limit on file size.

A limit smaller than necessary only means we divide a large

relation into more chunks than necessary, so it seems best to err

in the direction of a small limit.

A power-of-2 value is recommended to save a few cycles in md.c,
