We often want to format and print a string to a fd, usually stdout/stderr.
In general we can't use "format!", "print!", "eprint!" etc. because they don't
know about our use of WString where we encode of invalid Unicode characters
in the private use area.
Instead we use "wwrite_to_fd()".
Since we unfortunately don't have a "wformat!()" yet, we use "sprintf!()"
to create a formatted wstring to pass to "wwrite_to_fd()".
Add "printf!" and "eprintf!" to stand in for "print!" and "eprint!".
For printing to files other than stdout and stderr, keep "fwprintf!" but
drop the "w" since our "sprintf!" always produces wide strings.
Replace "fputws" with "fprintf" though we could also use "wwrite_to_fd"
if performance matters.
Unlike std::io::stdout(), we don't use locking yet.
Remaining work:
- There are more places where we use \be?print(ln)?!
Usually we print strings that are guaranteed to be valid UTF-8, but not
always. We should probably make all of them respect our WString semantics
but preferrably keep using the native Rust format strings (#9948).
- I think flog.rs currently uses String so it won't handle invalid Unicode
characters. We should probably fix this as well.
Drop support for history file version 1.
ParseExecutionContext no longer contains an OperationContext because in my
first implementation, ParseExecutionContext didn't have interior mutability.
We should probably try to add it back.
Add a few to-do style comments. Search for "todo!" and "PORTING".
