The new time warp safe option is safe_fixed_monotonic_time which
gives erlang:monotonic_time().
The safe_fixed option was also slightly changed. It now gives
erlang:timestamp() instead of erlang:now(). This has however
not been documented, so it is considered a compatible change.
The above effects both ets, and dets.
This commit also include the bugfix OTP-13239 for
dets:info(Tab, safe_fixed). The timestamp in the result returned
by dets:info(Tab, safe_fixed) was unintentionally broken as a
result of the time API rewrites in OTP 18.0.

New timestamp options for trace, sequential trace, and
system profile:
- monotonic_timestamp
- strict_monotonic_timestamp

This flag replaces the path specified in the boot script. It has
always existed, but was earlier only documented in SASL (script).

The nature of aux work is such that dirty schedulers should not
attempt to perform it. Modify the code to ensure that dirty schedulers
avoid aux work.
Also fix an incorrect assumption about the size of a Uint in the
ErtsDirtySchedId type.

Compiling OTP 18.2.1 with gcc-5.3 shows the following warning:
drivers/common/efile_drv.c:1538:23: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses]
The code in question is:
if (! (status =
erts_gzwrite((ErtsGzFile)d->fd,
iov[i].iov_base,
iov[i].iov_len)) == iov[i].iov_len) {
d->errInfo.posix_errno =
d->errInfo.os_errno = errno; /* XXX Correct? */
break;
}
If we hoist the assignment out of the if for clarity, it becomes:
status = erts_gzwrite(..., iov[i].iov_len);
if (! status == iov[i].iov_len) { ...; break; }
iov_len is > 0 here, and status will equal iov_len if erts_gzwrite
succeeded, but will be less than iov_len if an error occurred.
"! status" is 0 or 1, which can only equal iov_len if iov_len is 1 and
erts_gzwrite detected an error and returned 0.
The effect of this mistake is that any error when iov_len >= 2 will
skip the conditional code and break statement. In particular, partial
writes (0 < status && status < iov_len) will not be flagged as errors.
All releases since OTP R8B-0 are affected.
The variable "status" is really a boolean, which is to be set to zero
on error. The fix is to set status to 1 if erts_gzwrite() returned iov_len
and 0 otherwise, and to change the condition to "if (! status) ...".
I'm also hoisting the assignment out of the condition since it obscures
the code while providing not benefit (the condition in a while or for
loop would be a different matter).
