Matthew Bauer d0677e6d45 treewide: add warning comment to “boot” packages
This adds a warning to the top of each “boot” package that reads:

  Note: this package is used for bootstrapping fetchurl, and thus cannot
  use fetchpatch! All mutable patches (generated by GitHub or cgit) that
  are needed here should be included directly in Nixpkgs as files.

This makes it clear to maintainer that they may need to treat this
package a little differently than others. Importantly, we can’t use
fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale
hashes, we need to include patches that are subject to changing
overtime (for instance, gitweb’s patches contain a version number at
the bottom).

description = "A foreign function call interface library";
longDescription = ''
The libffi library provides a portable, high level programming
interface to various calling conventions. This allows a
programmer to call any function specified by a call interface
description at run-time.
FFI stands for Foreign Function Interface. A foreign function
interface is the popular name for the interface that allows code
written in one language to call code written in another
language. The libffi library really only provides the lowest,
machine dependent layer of a fully featured foreign function
interface. A layer must exist above libffi that handles type
conversions for values passed between the two languages.
