Add support for dynamic dependencies as byproduct of script body
Specifically, the `depdb dyndep` builtin now has the --byproduct option (which
must come first). In this mode only the --file input is supported. For example:
obje{hello.o}: cxx{hello}
{{
o = $path($>)
t = $(o).t
depdb dyndep --byproduct --what=header --default-type=h --file $t
diag c++ ($<[0])
$cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -MD -MF $t -c $path($<[0])
}}
Naturally, this mode does not support dynamic auto-generated prerequisites.
If present, such prerequisites must be specified statically in the buildfile.
Note also that the --default-prereq-type option has been rename to
--default-type.
