REORG: include: move stream.h to haproxy/stream{,-t}.h

This one was not easy because it was embarking many includes with it,
which other files would automatically find. At least global.h, arg.h
and tools.h were identified. 93 total locations were identified, 8
additional includes had to be added.

In the rare files where it was possible to finalize the sorting of
includes by adjusting only one or two extra lines, it was done. But
all files would need to be rechecked and cleaned up now.

It was the last set of files in types/ and proto/ and these directories
must not be reused anymore.
