[erlang-patches] Rename and document lists:zf/2 as lists:filtermap/2

[Anthony Ramine]

Hello,

I am tired of seeing lists:zf/2 hidden and unused outside of OTP even though it could help in some places, so I decided to rename it to a more useful name and document it.

	git fetch https://github.com/nox/otp.git lists-filtermap

	https://github.com/nox/otp/compare/erlang:maint...lists-filtermap
	https://github.com/nox/otp/compare/erlang:maint...lists-filtermap.patch

Regards,
