Modified files:
	usr.bin/make   : extern.h for.c str.c varmodifiers.c 

Log message:
Two new functions:

iterate_words: light-weight equivalent to brk_string,
which does not need to copy the string, and does not do \ interpretation
which are only needed for the string.

escape_dup: handles escape sequence in a systematic way.

This speeds up variable modifiers.

This also makes .for loops more consistent, as they use the same definition
of `a word' as the rest of make.
