7d734d9252 build: remove various uses of C undefined behavior
If you thought gcc -ansi -pedantic was pedantic, just wait
until you meet clang -fsanitize=undefined.

I think this addresses all the reported "errors", but we'll
need another run to be sure.

all.bash still passes.

Update #5764

Dave, can you please try again?

79dca0327e libbio, all cmd: consistently use BGETC/BPUTC instead of Bgetc/Bputc
Also introduce BGET2/4, BPUT2/4 as they are widely used.
Slightly improve BGETC/BPUTC implementation.
This gives ~5% CPU time improvement on go install -a -p1 std.

a570eaabcd 6l:
use libbio instead of maintaining own buffer

libbio:
	always use vlong offsets; die if off_t is too small
