[lwip-members] new dir name?

[Jani Monoses]

Hi
during the discussions about the layout of lwip sources
there was the idea of splitting core/ and moving support
code such as memalloc locking timers etc to a new dir.
Do you still think it's ok that way and if yes do you have any preferences
regarding the name . lib ? support? 

I want to put the ntohs functions duplicated across platforms in core too
and I thought that it should go in the new dir as well in the idea that
the stuff in this lib should be the one that can be replaced by the platform
(in this case CPU specific byteswap assembly intructions)

Comments are welcome

Jani.
