library/io.file.m:
library/io.m:
Move two sections of io.m, the "file handling predicates" section
and the "handling temporary files" section to the new submodule io.file.m.
Leave behind in io.m "forwarding predicates", predicates that do nothing
except call the moved predicates in io.file.m, to provide backward
compatibility. But do mark the forwarding predicates as obsolete,
to tell people to update their (at their leisure, since the obsoleteness
warning can be turned off).
Also leave behind in io.m the definitions of the two types used
by some parameters of some of the moved predicates. Document the reason
why this is done.

Call the file operation predicates directly in io.file.m, not indirectly
through io.m.
In two modules, add a #include of fcntl.h in C code. These modules contain
C code that needs this #include, but until now, they got it via a copy
in an automatically generated C header file of a foreign_decl pragma
in io.m that contained that #include. This diff moves that foreign_decl
to io.file.m, removing that crutch.

tests/hard_coded/*.m:
Update programming style, unless doing so would change
the meaning of the test, in particular:
- use '.' as a module qualifier in place of '__'
- use {write,print}_line where appropriate
- use if-then-else in place of C -> T ; E
- use state variables in place of DCGs
tests/hard_coded/dir_test.m:
Document what the expected outputs correspond to.
Use a uniform module qualifier in the output.

Conform to the above change.

Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.

library/io.m:
Reimplement `io.check_file_accessibility' for Java. The old version
would not work if a security manager was not set, which is the default.
On an error it could return a null error string, which is invalid.

Call `io.check_file_accessibility' with `execute' access type.

Move the univ, maybe, pair and unit types from std_util into their own

Library changes required to make the compiler work on Windows
without Cygwin. (Compiler changes to come separately).
library/dir.m:
Handle Windows-style paths.
Change the determinism of dir.basename and dir.split_name.
dir.basename now fails for root directories (a new function
dir.basename_det calls error/1 rather than failing).
dir.split_name fails for root directories or if the pathname
passed doesn't contain a directory separator.
Add predicates dir.make_directory, dir.path_name_is_absolute
and dir.path_name_is_root_directory.
Add a multi predicate dir.is_directory separator which
returns all separators for the platform (including '/' on
Windows), not just the standard one.
Add a function dir.parent_directory (returns "..").
Add dir.foldl2 and dir.recursive_foldl2, to iterate through
the entries in a directory (and maybe its subdirectories).
Change '/' to correctly handle Windows paths of the form
"C:"/"foo" and "\"/"foo".
Don't add repeated directory separators in '/'.
library/io.m:
Add io.file_type and io.check_file_accessibility.
Add predicates to deal with symlinks -- io.have_symlinks,
io.make_symlink and io.follow_symlink.
Add io.file_id for use by dir.foldl2 to detect
symlink loops. This is a bit low level, so it's
not included in the user documentation.
Add io.(binary_)input_stream_foldl2_io_maybe_stop, which
is like io.(binary_)input_stream_foldl2_io, but allows
stopping part of the way through. This is useful for
implementing `diff'-like functionality to replace
mercury_update_interface.
Use Windows-style paths when generating temporary file
names on Windows.
Add versions of the predicates to generate error messages
to handle Win32 errors.
Add versions of the predicates to generate error messages
which take a system error code, rather than looking up
errno. This simplifies things where the error we
are interested in was not from the last system call.
library/exception.m:
Add a predicate finally/6 which performs the same function
as the `finally' clause in languages such as C# and Java.
Add predicates try_det, try_io_det and try_store_det,
which only have one mode so they are more convenient
to pass to promise_only solution.
library/Mmakefile:
Add dependencies on runtime/mercury_conf.h for files which
use the MR_HAVE_* macros.
library/string.m:
Add a function version of string__index.
NEWS:
Document the new predicates and functions and the change
of determinism of dir.split_name and dir.basename.
configure.in:
runtime/mercury_conf.h.in:
Test for lstat, mkdir, symlink and readlink.
runtime/mercury_conf_param.h:
Add a macro MR_BROKEN_ST_INO, which is true if the st_ino
field of `struct stat' is garbage. Currently defined iff
MR_WIN32 is defined.
compiler/compile_target_code.m:
compiler/modules.m:
compiler/options_file.m:
