Add support for dynamic dependencies in ad hoc Buildscript recipes
Specifically, add the new `depdb dyndep` builtin that can be used to extract
dynamic dependencies from a program run or a file. For example:
obje{hello.o}: cxx{hello}
{{
s = $path($<[0])
depdb dyndep $cxx.poptions $cc.poptions --what=header --default-prereq-type=h -- $cxx.path $cxx.poptions $cc.poptions $cxx.mode -M -MG $s
diag c++ ($<[0])
o = $path($>)
$cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -c $s
}}
Currently only the `make` dependency format is supported.
