perf tools: Move parse_nsec_time to time-utils.c
Code move only; no functional change intended. Committer notes: Fix the build on Ubuntu 16.04 x86-64 cross-compiling to S/390, with this set of auto-detected features: ... dwarf: [ on ] ... dwarf_getlocations: [ on ] ... glibc: [ on ] ... gtk2: [ OFF ] ... libaudit: [ OFF ] ... libbfd: [ OFF ] ... libelf: [ on ] ... libnuma: [ OFF ] ... numa_num_possible_cpus: [ OFF ] ... libperl: [ OFF ] ... libpython: [ OFF ] ... libslang: [ OFF ] ... libcrypto: [ OFF ] ... libunwind: [ OFF ] ... libdw-dwarf-unwind: [ on ] ... zlib: [ on ] ... lzma: [ OFF ] ... get_cpuid: [ OFF ] ... bpf: [ on ] Where it was failing with: CC /tmp/build/perf/util/time-utils.o util/time-utils.c: In function 'parse_nsec_time': util/time-utils.c:17:13: error: implicit declaration of function 'strtoul' [-Werror=implicit-function-declaration] time_sec = strtoul(str, &end, 10); ^ util/time-utils.c:17:2: error: nested extern declaration of 'strtoul' [-Werror=nested-externs] time_sec = strtoul(str, &end, 10); ^ util/time-utils.c: In function 'perf_time__parse_str': util/time-utils.c:93:2: error: implicit declaration of function 'free' [-Werror=implicit-function-declaration] free(str); ^ util/time-utils.c:93:2: error: incompatible implicit declaration of built-in function 'free' [-Werror] util/time-utils.c:93:2: note: include '<stdlib.h>' or provide a declaration of 'free' Do as suggested and add a '#include <stdlib.h>' to get the free() and strtoul() declarations and fix the build.
