* hires.h (hires::usecs): Rename from utime. Accept an argument.

* strace.cc (strace::microseconds): Use hires class for calculating times.
* sync.h (new_muto): Use NO_COPY explicitly in declaration.
* times.cc (gettimeofday): Reflect change in usecs argument.
(hires::usecs): Ditto.  Changed name from utime.
* winsup.h (NO_COPY): Add nocommon attribute to force setting aside space for
variable.
* regcomp.c (REQUIRE): Add a void cast to bypass a warning.
