e39a73cc55 doc: Don't mention top-level {build, host, target}Platform
For technical reasons, we cannot easily add a warning to top-level
definitions, so 2a6e4ae49a and
e51f736076 reverted the deprecation. But
we can still remove mention of the would-be deprecated definitions to
steer people towards using the preferred alternatives.

e51f736076 top-level: Deprecate top-level {build,host,target}Platform
I don't know when we can/should remove them, but this at least gets
people to stop using them. The preferred alternatives also date back to
17.09 so writing forward-compatable code without extra conditions is
easy.

Beginning with these as they are the least controversial.

7ffc4e1b2f doc: Add "Specifying Dependencies" section to the stdenv chapter
This accounts for all the new dependencies and propagation logic changes
I'm about to add.

Fixes #1915---with this change I think the distinction is finally clear
enough.

863d79b364 top-level: Introduce targetPackages and a "double link fold"
Each bootstrapping stage ought to just depend on the previous stage, but
poorly-written compilers break this elegence. This provides an easy-enough
way to depend on the next stage: targetPackages. PLEASE DO NOT USE IT
UNLESS YOU MUST!

I'm hoping someday in a pleasant future I can revert this commit :)

8cd4c31d6b top-level: Allow nixpkgs to take localSystem directly
This is instead of both system and platform, which is kind of ugly.

5eaea6cee0 cross stdenv: let build package's build deps resolve to native packages
This fixes the "sliding window" principle:
  0. Run packages:       build = native;  host = foreign; target = foreign;
  1. Build packages:     build = native;  host = native;  target = foreign;
  2. Vanilla packages:   build = native;  host = native;  target = native;
  3. Vanilla packages:   build = native;  host = native;  target = native;
  n+3. ...

Each stage's build dependencies are resolved against the previous stage,
and the "foreigns" are shifted accordingly. Vanilla packages alone are
built against themsevles, since there are no more "foreign"s to shift away.

Before, build packages' build dependencies were resolved against
themselves:
  0. Run packages:       build = native;  host = foreign; target = foreign;
  1. Build packages:     build = native;  host = native;  target = foreign;
  2. Build packages:     build = native;  host = native;  target = foreign;
  n+2. ...

This is wrong because that principle is violated by the target
platform staying foreign.

This will change the hashes of many build packages and run packages, but
that is OK. This is an unavoidable cost of fixing cross compiling.

The cross compilation docs have been updated to reflect this fix.
