library/io.m:
Add two new predicates.
The new predicate read_named_file_as_string reads in a named file,
and returns its contents as a single giant string. This is effectively
a combination of open_input, read_file_as_string, and close_input.
The new predicate read_named_file_as_lines reads in a named file,
and returns its contents as a list of strings, each containing
the contents one line (minus the newline char at the end, if any).
This is effectively a combination of open_input, read_file_as_string,
split_into_lines (see below), and close_input.
library/string.m:
Add a new function, split_into_lines, which breaks up a string into
its constituent lines, returning each line minus its newline.
This differs from the old split_at_char('\n', ...) in that it
expects the input string to end with a newline, and does not return
an empty string after a final newline. (If there *are* characters
after the final newline, it does return *them* as the final line.)
NEWS:
Announce the new predicates and function.
compiler/source_file_map.m:
Use the new functionality to simplify the code that reads in
Mercury.modules files.
tests/hard_coded/string_split.{m,exp}:
Add tests for split_into_lines.

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/string.m:
Fix an off-by-one bug in string.split_at_separator. The index in the
initial call to split_at_separator2 was one past the end of the
string, which worked in the C backends because strings are NUL
terminated.
Rename split_at_separator2 to split_at_separator_2 and make it more
readable.
tests/hard_coded/string_split.exp:
tests/hard_coded/string_split.m:
Add a couple of cases which seem more likely to fail with an incorrect
implementation.
Estimated hours taken: 3
Branches: main
A few handy functions for splitting a string added.
library/string.m:
Added remove_suffix_if_present, split_at_separator, split_at_char,
split_at_string
tests/hard_coded/string_split.m:
A simple test of split_at_* functions.
tests/hard_coded/string_split.exp:
Expected results of the tests of split_at_* functions.
tests/hard_coded/string_various.m:
Created. Added testcase for remove_suffix_if_present.
tests/hard_coded/string_various.exp:
Created. Added results for remove_suffix_if_present.
NEWS:
Added a comment that the functions have been added.
