[PATCH 0/4 v3] Revise crypto documentation, deprecate DES, add --disable-crypt

[Zack Weinberg <zackw at panix dot com>]

As requested by Rical Jasan, this revision of the patchset
<https://sourceware.org/ml/libc-alpha/2018-04/msg00628.html> carefully
splits the documentation changes into one patch that just moves text
around, and another patch that changes text but doesn't move it.  I
have also made some more improvements to the documentation.  There are
no new changes to code.

I agree that "Obsolete Encryption" does not need to be its own
chapter; in this revision it goes back to being a subsection of
crypt.texi.  "Random Number Generation" is still a new independent
chapter.  This is because I want to put "Unpredictable Bytes" right
after "Pseudo-Random Number Generation", and it doesn't seem to make
sense to have that consolidated subtree be either with math.texi or
crypt.texi.

I am not sure whether I remembered to address all of your other
comments on the documentation changes, but I got the impression you
wanted to re-review it from scratch anyway after the split-up?

Zack Weinberg (4):
  Reorganize manual sections on cryptography and random numbers.
  Revise manual sections on cryptography and random numbers.
  Deprecate DES encryption functions.
  New configure option --disable-crypt.
