* ADD new /src/common/crypto_rand.[ch] module.
 * ADD new /src/common/crypto_util.[ch] module (contains the memwipe()
   function, since all crypto_* modules need this).
 * FIXES part of #24658: https://bugs.torproject.org/24658

The earlier checks in this function should ensure that components is
always nonempty.  But in case somebody messes with them in the
future, let's add an extra check to make sure we aren't crashing.

Per discussion on 25055.

Apparently, sometimes getpwnam will call this.

Fixes bug 25513.

These declarations need to exist unconditionally, but they were
trapped inside an "#else /* !(defined(HAVE_SYSLOG_H)) */" block.

Fixes a travis regression caused by 23881; bug not in any released tor.

 * ADD include for "crypto_openssl_mgt.h" so that we have OpenSSL
   defined SHA* types and functions.
 * FIXES part of #24658: https://bugs.torproject.org/24658#comment:30

 * ADD includes for "torint.h" and "container.h" to crypto_digest.h.
 * ADD includes for "crypto_digest.h" to a couple places in which
   crypto_digest_t was then missing.

Folks have found two in the past week or so; we may as well fix the
others.

Found with:

\#!/usr/bin/python3
import re

def findMulti(fname):
    includes = set()
    with open(fname) as f:
        for line in f:
            m = re.match(r'^\s*#\s*include\s+["<](\S+)[>"]', line)
            if m:
                inc = m.group(1)
                if inc in includes:
                    print("{}: {}".format(fname, inc))
                includes.add(m.group(1))

import sys
for fname in sys.argv[1:]:
    findMulti(fname)

Fixes a bug in our zstd-static code.  Bug not in any released
version of Tor.

We moved the crypto_pk_obselete_* functions into crypto_rsa.[ch] because they fit
better with the RSA module.

Follows #24658.

This is necessary because apparently v3 rendezvous cpath hops use
sha3, which I had forgotten.

Bugfix on master; bug not in any released Tor.

Add an autoconf test to make sure we won't regret it.

Closes ticket 24484.

We don't expect this to come up very much, but we may as well make
sure that the value isn't predictable (as we do for the other
addresses) in case the issue ever comes up.

Spotted by teor.

This patch lowers the log-level from warning to info in the cases where
we are going to attempt another method as entropy source to hopefully
make the user feel less concerned.

This is a convenience function, so callers don't need to wrap
the IPv4 address.

We're going to need this to make our anti-DoS code (see 24902) more
robust.

some of these ought to have been noticed by the "misspell" tool,
so if anybody is debugging it, here are some bug reports :)
