extras/posix/posix.strerror.m:
Fix use of MR_strerror (it may return a pointer to a static string
instead of modifying the provided buffer).
Allocate string such that it will be attributed to the predicate
when profiling memory retention.
The binding for readdir() was reporting the end of the directory stream as an
unknown error. This problem was reported by Volker Wysk, to whom the initial
version of the fix is also due.
extras/posix/posix.readdir.m:
Add a new result type that distinguishes between the end of the directory
stream and an error.
Add and export to C an enumeration whose values describe the result of
a call to readdir(). Use this, rather than small integers, when
communicating the result of readdir() call back to Mercury.
Always the string output argument of a foreign_proc to a valid value;
this avoids problems if the debugger attempts to print them out.
Delete the workarounds for FD_{ZERO,SET,ISSET,CLR} in the POSIX binding. The
stated reason for their existence was that the Linux headers defined them using
inline assembler that conflicted with our use of global register variables.
Since the runtime (now) defines a wrapper for FD_ZERO, use the runtime's
version instead of having the binding define its own. We've been using
FD_{SET,ISSET} in the runtime without issues for many years. (On my system,
they and FD_CLR are not defined using inline assembler anyway.)

Deprecate string.substring, string.foldl_substring, etc. in favour of
new procedures named string.between, string.foldl_between, etc.
The "between" procedures take a pair of [Start, End) endpoints instead
of Start, Count arguments. The reasons for this change are:
- the "between" procedures are more convenient
- "between" should be unambiguous. You can guess that it takes an End
argument instead of a Count argument without looking up the manual.
- Count arguments necessarily counted code units, but when working with
non-ASCII strings, almost the only way that the values would be arrived at
is by substracting one end point from another.
- it paves the way for a potential change to replace string offsets with an
abstract type. We cannot do that if users regularly have to perform a
subtraction between two offsets.
library/string.m:
Add string.foldl_between, string.foldl2_between,
string.foldr_between, string.between.

former is more type safe. (TODO: there are quite a few remaining uses
of c_pointer in these modules that could be replaced by foreign
types.)
Put no_inline pragmas on foreign_procs containing static data so we
don't end up duplicating that data.
(TODO: the static data should be shifted into foreign_code pragmas, but
that's a separate change.)
Rename posix.socket.(type)/0 to socket_type/0. This avoids having to

Likewise change the rule for `depend' so that it builds
`posix.depend' as well as `hello.depend'.
- Change the rule for `check' so that it runs `hello'.
- Use $O and $(EXT_FOR_PIC_OBJECTS) rather than hard-coding `.o'.
