Subject: [PATCH] path.c: Fix a static buffer overwrite bug by avoiding mkpath()

In order to fix the bug, we introduce a new variation of the mkpath()
function, mkpathdup(), which avoids the use of the internal static
buffers.

Shouldn't we aim a bit higher to also avoid the use of bounded
buffer?  Instead of returning bad_path, retry with lengthened buffer
until we succeed, or something.

Better yet, internally use strbuf_vaddf().
