Sanitize leading dots from log path components

Prevent directory traversal by sanitizing leading dots as well as
slashes from log path components, which can be controlled by the
server. Side effect of preventing hidden dotfiles is a bonus, I
think.

Also check that the full path actually fits in the buffer.
