Declare and define a global default struct wget_http_info
and an interface to issue wget requests providing a custom
struct wget_http_info. This code is common to legacy wget
and lwip wget. The idea is that the command wget should use
the default wget_http_info and other internal u-boot code
can call wget_request with their own wget_http_info struct.

Changes in v2:
- Instead of having a single global wget_http_info struct, let
  the user of wget (e.g. the efi code) provide an instance of
  wget_http_info to wget with the desired parameters. This lets
  the user cache the wget paramenters in their wget_http_info
  struct as desired (e.g. the content length from a HEAD request
  to a subsequent GET request, see the next efi patch). 
  If none is provided, wget uses default_wget_info.
- Add wget_request to trigger a wget request with a custom
  wget_http_info struct.
