sys-limits.h: new file for crypto and safe I/O * lib/af_alg.c: Include sys-limits.h. (MAX_RW_COUNT): Remove. Use replaced by SYS_BUFSIZE_MAX. (afalg_stream): Also reject negative sizes for sendfile; they should not happen and the code is a bit cleaner and faster this way. * lib/safe-read.c: Include sys-limits.h. (BUGGY_READ_MAXIMUM): Remove. All uses replaced by SYS_BUFSIZE_MAX. * lib/sys-limits.h: New file, with values and commentary derived from the old safe-read.c and from GNU Emacs sysdep.c. * modules/crypto/md5, modules/crypto/sha1, modules/crypto/sha256: * modules/crypto/sha512, modules/safe-read, modules/safe-write: Add lib/sys-limits.h to Files section.
