Fetches a HTTP form variable.
Fetches a variable `name` from a `buf` into a buffer specified by
`dst`, `dst_len`. The destination is always zero-terminated. Returns the length
of a fetched variable. If not found, 0 is returned. `buf` must be
valid url-encoded buffer. If destination is too small, `-1` is returned.
