Dr. Matthias St. Pierre a08714e181 Revert the DEVRANDOM_WAIT feature
The DEVRANDOM_WAIT feature added a select() call to wait for the
`/dev/random` device to become readable before reading from the
`/dev/urandom` device. It was introduced in commit 38023b87f0
in order to mitigate the fact that the `/dev/urandom` device
does not block until the initial seeding of the kernel CSPRNG
has completed, contrary to the behaviour of the `getrandom()`
system call.

It turned out that this change had negative side effects on
performance which were not acceptable. After some discussion it
was decided to revert this feature and leave it up to the OS
resp. the platform maintainer to ensure a proper initialization
during early boot time.

Fixes #9078

This partially reverts commit 38023b87f0.

 OpenSSL 3.0.0-dev

 Copyright (c) 1998-2018 The OpenSSL Project
 Copyright (c) 1995-1998 Eric A. Young, Tim J. Hudson
 All rights reserved.

 DESCRIPTION
 -----------

 The OpenSSL Project is a collaborative effort to develop a robust,
 commercial-grade, fully featured, and Open Source toolkit implementing the
 Transport Layer Security (TLS) protocols (including SSLv3) as well as a
 full-strength general purpose cryptographic library.

 OpenSSL is descended from the SSLeay library developed by Eric A. Young
 and Tim J. Hudson.

 The OpenSSL toolkit is licensed under the Apache License 2.0, which means
 that you are free to get and use it for commercial and non-commercial
 purposes as long as you fulfill its conditions.

 OVERVIEW
 --------

 The OpenSSL toolkit includes:

 libssl (with platform specific naming):
     Provides the client and server-side implementations for SSLv3 and TLS.

 libcrypto (with platform specific naming):
     Provides general cryptographic and X.509 support needed by SSL/TLS but
     not logically part of it.

 openssl:
     A command line tool that can be used for:
        Creation of key parameters
        Creation of X.509 certificates, CSRs and CRLs
        Calculation of message digests
        Encryption and decryption
        SSL/TLS client and server tests
        Handling of S/MIME signed or encrypted mail
        And more...

 INSTALLATION
 ------------

 See the appropriate file:
        INSTALL         Linux, Unix, Windows, OpenVMS, ...
        NOTES.*         INSTALL addendums for different platforms

 SUPPORT
 -------

 See the OpenSSL website www.openssl.org for details on how to obtain
 commercial technical support. Free community support is available through the
 openssl-users email list (see
 https://www.openssl.org/community/mailinglists.html for further details).

 If you have any problems with OpenSSL then please take the following steps
 first:

    - Download the latest version from the repository
      to see if the problem has already been addressed
    - Configure with no-asm
    - Remove compiler optimization flags

 If you wish to report a bug then please include the following information
 and create an issue on GitHub:

    - OpenSSL version: output of 'openssl version -a'
    - Configuration data: output of 'perl configdata.pm --dump'
    - OS Name, Version, Hardware platform
    - Compiler Details (name, version)
    - Application Details (name, version)
    - Problem Description (steps that will reproduce the problem, if known)
    - Stack Traceback (if the application dumps core)

 Just because something doesn't work the way you expect does not mean it
 is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
 of query.

 LEGALITIES
 ----------

 A number of nations restrict the use or export of cryptography. If you
 are potentially subject to such restrictions you should seek competent
 professional legal advice before attempting to develop or distribute
 cryptographic code.
