Let benchmark.report_stats/0 report real times on POSIX platforms.
configure.in:
Check for time.h and gettimeofday().
runtime/mercury_conf.h.in:
Add MR_HAVE_TIME_H, MR_HAVE_GETTIMEOFDAY.
Unrelated change: add MR_HAVE_PTHREAD_H.
runtime/mercury_timing.c:
runtime/mercury_timing.h:
Add `MR_get_real_milliseconds'.
runtime/mercury_wrapper.c:
runtime/mercury_wrapper.h:
Rename MR_time_* globals to MR_user_time_*.
Add and initialise MR_real_time_* globals.
library/benchmarking.m:
Output real times in ML_report_stats().
Correct spelling of milliseconds.
java/runtime/Native.c:
java/runtime/Native.java.in:
trace/mercury_trace_declarative.c:
Correct spelling of milliseconds.

Implement some library procedures for the Java back-end.
library/time.m:
Implement c_clk_tck/0 for Java. Also changed the C implementation to
use the same macro as that used in Native.c.
java/runtime/Native.java.in:
Add new function clk_tck() to be called by c_clk_tck/0.
java/runtime/Native.c:
Add corresponding implementation for clk_tck().

Branches: main
Implement some library predicates for Java using JNI.
java/runtime/Native.java.in:
A new class which uses JNI to provide any native functionality
required by predicates of the standard library in Java.
So far it only provides methods relating to timing.
java/runtime/Native.c:
Source code, written in C, which implements all the native methods of
mercury.runtime.Native. Note that this implementation makes use of the
existing C implementation of the equivalent functions.
java/runtime/Mmakefile:
Rules for compiling a shared object from Native.c.
library/time.m:
Implement the following predicates for Java using Native interface:
time__c_clock/3
time__clocks_per_sec/1
time__times/7
library/benchmarking.m:
Implement the following predicates for Java using Native interface:
get_user_cpu_miliseconds/1
library/Mmakefile:
Renamed to library/Mmakefile.in, so as to have access to FULLARCH
constant.
library/Mmakefile.in:
Added rules for incorporating the Native shared object.
