Fix prototypes.

Remove extraneous decls.
Add ``const'' to several places.
Allow ``make NOALIAS=1'' to remove IP aliasing.
Merge with OpenBSD - only the Makefiles vary.

We can now survive a compile with
  -Wall -Wbad-function-cast -Wcast-align -Wcast-qual
  -Winline -Wmissing-declarations -Wmissing-prototypes
  -Wnested-externs -Wpointer-arith -Wredundant-decls
  -Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts
(although the Makefile just contains -Wall).
