Make use of the crate's prelude to replace individual imports

This step was performed automatically with the following:

    #!/bin/bash

    set -eux

    files=()
    prelude_types=(
        c_char

        ssize_t
        Clone
        Copy
        Option
    )

    # Generate a list of all files excluding `lib.rs` (since the prelude being
    # defined there makes string matching weird).
    while IFS= read -r -d '' file; do
        files+=("$file")
    done < <(find src -name '*.rs' -not -name 'lib.rs' -print0)

    for file in "${files[@]}"; do
        # If the file already has some sort of glob import, skip it
        if rg --pcre2 -q 'use crate::(?!prelude).*\*' "$file"; then
            continue
        fi

        # Core types always require the prelude to handle rustc-dep-of-std
        if rg -qU "(Option|Clone|Copy)" "$file"; then
            needs_prelude=1
        fi

        for ty in "${prelude_types[@]}"; do

                needs_prelude=1
            fi
        done

        # Check if the prelude is needed and does not already exist; if so, add it
        if [ "${needs_prelude:-}" = "1" ] && ! rg -q "use crate::prelude::\*" "$file"; then

            # Remove simple imports `use crate::ty;`
            perl -pi -0777 -e 's/use crate::($ENV{TY});//g' "$file"

            # Replace pathed `crate::ty`
            perl -pi -0777 -e 's/crate::($ENV{TY})\b/$1/g' "$file"

            # Remove the type if it is part of a group import
            perl -pi -0777 -e 's/(use crate::\{?(.*|(\n.*){,2}))\b$ENV{TY}\b,? ?/$1/g' "$file"
        done

        # For some reason, rustfmt doesn't trim leading newlines. Do so manually here.
        perl -pi -0777 -e 's/\A\n+//' "$file"
