For open/openat, if the flags parameter does not contain O_CREAT, the
3rd (variadic) mode_t parameter is irrelevant. Many developers in the past
have passed mode_t (0, 044, 0644, or such), which might lead future people
to copy this broken idiom, and perhaps even believe this parameter has some
meaning or implication or application. Delete them all.
This comes out of a conversation where tb@ noticed that a strange (but
intentional) pledge behaviour is to always knock-out high-bits from
mode_t on a number of system calls as a safety factor, and his bewilderment
that this appeared to be happening against valid modes (at least visually),
but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef.

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

Implement the conv=fsync feature which does an fsync(2) after the
final write to output. GNU dd also has this. It is useful for
write performance measurement or guaranteed writes to reliable
storage.

Don't cast malloc(3) size to u_int.

Large buffer sizes on 64-bit platforms cause the sum to wrap, leading
read(2) to fail later.

We check prior to this point that all buffer sizes are <= SSIZE_MAX.
SSIZE_MAX * 2 < SIZE_MAX on all platforms, so the addition here will
not overflow and cause a similar issue.

Remove the advertising clause in the UCB license which Berkeley

Fix ``echo foo |dd'' which was broken by the last commit.

Move check for count=0 into dd's main. We want to do normal setup

Fixes a problem noted by aaron@ where the time portion of the summary
would be wrong and also gives us sane behavior when seek is non-zero
but count is 0.

Modify timekeeping in an effort to produce a sane bandwidth measure
for a short running dd process. Some floating point is used so that
microsecond precision can be kept without shortening the off_t
excessively. millert says ok.
