Patch 7.2.167

Problem:    Splint doesn't work well for checking the code.

Solution:   Add splint arguments in the Makefile.  Exclude some code from

	    splint that it can't handle.  Tune splint arguments to give

	    reasonable errors.  Add a filter for removing false warnings from

	    splint output.  Many small changes to avoid warnings.  More to

	    follow...

Files:	    Filelist, src/Makefile, src/buffer.c, src/charset.c,

	    src/cleanlint.vim, src/digraph.c, src/edit.c, src/ex_cmds.c,
