net: lwip: wget: rework the '#' printing

Currently, the LWIP wget command prints excessive amount of progress
indicator '#' for very long file downloads, limit this to one line
that scales according to transfer size.

The HTTP server does report the size of the entire file in protocol
headers, which are received before the actual data transfer. Cache
this information and use it to adaptively print progress indicator
'#' until it fills one entire line worth of '#', which indicates the
transfer has completed. This way, long transfers don't print pages of
'#', but every transfer will print exactly one line worth of '#'. The
algorithm for '#' printing is the same as TFTP tsize one.
