build: Allow explicit module dependencies

Browse Source

The build system deduces inter-module dependencies from the symbols
required and exported by the modules. This works well, except for some
rare cases where the dependency is indirect or hidden. A module might
not make use of any function of some other module, but still expect its
functionality to be available to GRUB.

To solve this, introduce a new file, currently empty, called extra_deps.lst
to track these cases manually. This file gets processed in the same way
as the automatically generated syminfo.lst, making it possible to inject
data into the dependency resolver.

Since *.lst files are set to be ignored by git, add an exception for
extra_deps.lst.

Additionally, introduce a new keyword for the syminfo.lst syntax:
"depends" allows specifying a module dependency directly:

  depends <module> <depdendency>...
