Convert cgit_print_error to a variadic function
This removes many uses of "fmt" which uses a fixed size static pool of fixed size buffers. Instead of relying on these, we now pass around argument lists for as long as possible before using a strbuf to render content of an arbitrary size. Signed-off-by: John Keeping <john@keeping.me.uk>
