This PR adds two new rules: copy_file and copy_xfile. Both rules solve a common problem: to copy one file to another location. The problem is routinely solved using a genrule. That however requires Bash, since genrules execute Bash commands. Requiring Bash is a problem on Windows. The new rules do not require Bash on Windows (only on other platforms). The only difference between the rules is that copy_xfile creates an executable file while copy_file doesn't. See https://github.com/bazelbuild/bazel/issues/4319

"""A rule that copies a file to another place.
|
|
|
|
native.genrule() is sometimes used to copy files (often wishing to rename them).
|
|
The 'copy_file' rule does this with a simpler interface than genrule.
|
|
|
|
The rule uses a Bash command on Linux/macOS/non-Windows, and a cmd.exe command
|
|
on Windows (no Bash is required).
