ludicc / ludic build: --stdin-file <path> checks an unsaved buffer in place of its file (R10)

Browse source 
stdin is read once, whole, and read_file serves a copy of it wherever the program opens <path> -
the entry, an import through a barrel, a component's .xml / .lss, an .lres. Paths match after
normalising both ('/' separators, relative under $PWD, . / .. / // folded, case on Windows);
diagnostics keep the file's usual name, with the buffer's lines and columns. A <path> nothing
opens is one warning. On ludic build it implies --check. Reseeded; bootstrap-cfree fixpoint holds.
