This commit introduces an extended configuration syntax for linking
files and directories. Currently, this syntax allows for specifying
items to be forcibly linked, overwriting existing files or directories
if necessary.
The extended configuration syntax was proposed by Travers McInerney
<travers@mcinerney.me>.
When failing to symbolically linking files, display the names of the
files that could not be linked. This makes it easier to troubleshoot the
error without having to manually figure out which files failed to link.
Linker now reports an error when links are configured to point to
nonexistent targets. This fixes the old behavior where Linker silently
created invalid links.
