Cleaned up runtime directory.
runtime/*.c:
- Renamed all .c files as mercury_*.c
Some have been renamed to make their purpose clearer.
call.mod -> mercury_ho_call.c
runtime/*.h:
- Moved contents of .h files to mercury_*.h
- *.h now contain #include mercury_*.h. They be removed later.
- Updated references to conf.h -> mercury_conf.h
runtime/conf.h.in:
- Renamed conf.h.in as mercury_conf.h.in.
Didn't leave a forwarding header for this one, as conf.h was
never part of the repository anyway.
runtime/Mmakefile:
- Convert lists to one-per-line lists.
- Add mercury_accurate_gc.h to HDRS.
- Remove all .mod files
- Make sure runtime.init uses the ORIG_CS not MOD_CS.
- Fix the rules for "clean_o" and "clean_mod_c", which used
wildcards like "*.o" to remove files. The one that removed
all .c files corresponding with *.mod, instead of using MOD_CS
was particularly vicious.
- Cope with the file renamings.
configure.in:
- Cope with the file renamings.

This diff starts migrating global variables into virtual registers,
removes some junk code to do with parallelism, and renames the
special registers with MR_ prefixes.
compiler/llds_out.m:
rename hp, etc as MR_hp, etc.
library/std_util.m:
rename hp and solutions_heap_pointer.
runtime/*:
- remove old parallelism stuff that will change completely when
we use posix threads.
- rename the various special registers (hp, sp, etc) with a MR_
prefix.
- make the solutions heap pointer and the minimum heap reclaimation
point virtual registers rather than global variables.
Estimated hours taken: 0.25
runtime/mercury_float.h:
Fix a bug in the code for word_to_float() and float_to_word()
for non-gcc compilers that prevented it from compiling.
Estimated hours taken: 4
Add new predicate `float__hash' to the standard library for computing a
non-negative integer hash value for a float.
Add a C function to the runtime to do the actual hashing. This
function is in the runtime so that it can be called from both
the library and from C code generated for `pragma fact_table'
indexing.
library/float.m
Add a new predicate `float__hash' that calls the runtime
function `hash_float()'.
runtime/mercury_float.h
Add a declaration for `hash_float()'.
runtime/mercury_float.c
Add new file mercury_float.c for runtime code related to
floats.
Add a new function `hash_float()' for hashing floats.

A general cleanup of the code in the runtime directory, aimed at
formulating a more coherent header file inclusion policy. This change
fixes a couple of bugs that prevented the runtime from compiling in
certain configurations (e.g. on muse) due to missing #includes, and
also fixes a few minor unrelated things such as the use of `size_t'
instead of `unsigned'.
Our header file inclusion policy is that every header file should
#include any other header files needed by the declarations or by the
macros it defines. Cyclic interface dependencies, where two header
files each #include the other, must be avoided (by splitting up header
files into smaller indepdent units, if necessary).
At some stage in the future we should rename all the header files to
`mercury_*.h', to avoid any possible name clashes with system or user
header files.
runtime/Mmake:
Add a new target `check_headers' to check that each
header file is syntactically valid in isolation.
runtime/imp.h:
runtime/mercury_float.h:
runtime/mercury_string.h:
runtime/mercury_types.h:
runtime/calls.h:
Move the code in "imp.h" into new header files.
"imp.h" now contains nothing but #includes.
runtime/conf.h.in:
runtime/*.h:
runtime/{label,prof,prof_mem}.c:
runtime/*.mod:
Update the #includes to reflect the new header file structure.
Add some missing header guards. Add some comments.
Put the correct years in most of the copyright notices.
runtime/heap.h:
Fix a bug: add #include "context.h", needed for
min_heap_reclamation_point.
runtime/context.h:
Fix a bug: add #include "memory.h", needed for MemoryZone.
Move the general description comment to the top of the file.
Fix the indentation of some comments. Add a couple of new comments.
runtime/context.mod:
Delete a couple of unnecessary declarations.
runtime/wrapper.mod:
Change the type used for memory sizes from `unsigned' to `size_t'.
Change the `-p' (primary cache size) option so that it is always
a size in kilobytes, rather than being schitzophrenic about
whether it is bytes or kilobytes.
runtime/regorder_base.h:
Removed, since it not used (and constitutes a
double-maintenance problem).
