Add a new make macro for creating <file> from <file>.in at build

$(foreach file,$(IN_TARGETS),$(eval $(call apply-build-vars,$(file))))

This can be used instead of the current approach to perform the similar
step for file.in during ./configure.

This will avoid having to run ./configure just because of modifying a
file depending on a variable set by configure.

Prepare to have multiple files as source for the replacement patterns.

V2:
- don't use pattern rule, but create explicit dependency in macro,
    don't require to rename source files (Jan Beulich, Andrew Cooper)
V3:
- prepare for $(PATH_FILES) to be extended by other Makefile
- let generated file depend on $(INC_FILES)

Everything else in the series is looking fine now.  But why is
PATH_FILES dropping the .mk extension from the file?

It looks weird for both INC_FILES and BUILD_MAKE_VARS to have to
re-insert it.

Hmm, right.

Let me change that.

If it's only that, I could fix up on commit to save another posting.

You need to fix up patch 4, too (in tools/Rules.mk).

Thanks,
