Hi James,

The PATH_MAX usage in lib/urldata.h still breaks builds and I hesitate to
release until we have this sorted.

Also, I've taken a look at this and I think we should reconsider the use of
this define:

It is by default set to 4096 on many systems, and having two variables of that
size by default in a struct is needlessly gonna add some 8K of memory use for
every single connection (for libcurls with SSH-capabilities enabled). I think
we should rather malloc-on-demand instead.

I think the asprintf() function should come handy for this.

So what do you think about this?
