a245fc1835
This patch doesn't seem much useful alone, I must admit. However, it makes sense as part of the upcoming directory reorganization, where I want to have include/net/tap.h as the net<->hw interface for tap. Then having both net/tap.h and include/net/tap.h does not work. "Fixed" by moving all the init functions to a single header file net/clients.h. The patch also adopts a uniform style for including net/*.h files from net/*.c, without the net/ path.
