Based on Junio's suggestion, this patch moves quote_path() from
wt-status.c to quote.c and renames it as quote_path_relative(),
because it is a better name for a public function.
Also, instead of handcrafted quoting, quote_c_style_counted() is now
used, so it will honor core.quotepath specified in configuration.
The whole path is quoted now (as it was before in the scripted version
of git status before it was rewritten in C).
I have put strbuf_setlen() before strbuf_grow(), because otherwise
strbuf_grow() will increase the buffer on top of the context of the
buffer that we discard by setting the buffer length to zero.

This version of patch has been changed to put in double quotes only
those names that have escaped characters in them. Names containing
spaces or single quotes are not quoted, but it is consistent with
how all other functions work (for instance, write_name_quotedpfx).
If we want quote names consisting of spaces and single quotes, I will
prepare a separate patch.
