timespec: prefer ‘assume’ to ‘assure’

This avoids some runtime tests. The rest of the module makes
similar assumptions and there is little point to testing here.
* lib/timespec.h: Include verify.h instead of assure.h.
(timespec_cmp): Use ‘assume’, not ‘assure’.
Also, remove an unnecessary cast to ‘int’, as lots of other
code in this module now causes -Wconversion to complain, and
this is a problem with -Wconversion not with the code.

* modules/timespec (Depends-on): Depend on ‘verify’, not ‘assure’.

Port recent gnulib-tool change to Dash

* gnulib-tool (func_create_testdir): Don't assume that the shell
retokenizes after expanding "$@" inside the call to
func_execute_command. Dash 0.5.8-2.1ubuntu2 does not.

timespec.h: use "assure" to avoid a spurious warning

* lib/timespec.h: Include "assure.h" and use it to help
gcc7's -Wstrict-overflow avoid a false positive warning
for a use in coreutils' ls.c. Suggested by Paul Eggert in
https://lists.gnu.org/r/bug-gnulib/2017-10/msg00007.html
* modules/timespec (Depends-on): Add assure.

Avoid several test failures with traditional locales on Haiku.

411ad11... by Bruno Haible on 2017-10-29

strerror_r-posix: Fix behaviour and test failure on Haiku.

* lib/strerror_r.c (strerror_r): Don't assume that valid error numbers
are positive. Work around return value 0 instead of ERANGE on Haiku.
For unknown error numbers, use a format string consistent with perror().
* doc/posix-functions/strerror_r.texi: Mention the Haiku problem.
* tests/test-strerror_r.c (main): Don't assume that valid error numbers
are positive.

ilogbl: Ensure replacement on Haiku.
