New function EVP_CIPHER_free()

This function re-implements EVP_CIPHER_meth_free(), but has a name that
isn't encumbered by legacy EVP_CIPHER construction functionality.

We also refactor most of EVP_CIPHER_meth_new() into an internal
evp_cipher_new() that's used when creating fetched methods.

EVP_CIPHER_meth_new() and EVP_CIPHER_meth_free() are rewritten in terms of
evp_cipher_new() and EVP_CIPHER_free().  This means that at any time, we can
deprecate all the EVP_CIPHER_meth_ functions with no harmful consequence.

openssl dgst, openssl enc: check for end of input

The input reading loop in 'openssl dgst' and 'openssl enc' doesn't
check for end of input, and because of the way BIO works, it thereby
won't detect that the end is reached before the read is an error.
With the FILE BIO, an error occurs when trying to read past EOF, which
is fairly much ok, except when the command is used interactively, at
least on Unix.  The result in that case is that the user has to press
Ctrl-D twice for the command to terminate.

The issue is further complicated because both these commands use
filter BIOs on top of the FILE BIO, so a naïve attempt to check
BIO_eof() doesn't quite solve it, since that only checks the state of
the source/sink BIO, and the filter BIO may have some buffered data
that still needs to be read.  Fortunately, there's BIO_pending() that
checks exactly that, if any filter BIO has pending data that needs to
be processed.

We end up having to check both BIO_pending() and BIO_eof().

Start up DEVRANDOM entropy improvement for older Linux devices.

Improve handling of low entropy at start up from /dev/urandom by waiting for
a read(2) call on /dev/random to succeed.  Once one such call has succeeded,
a shared memory segment is created and persisted as an indicator to other
processes that /dev/urandom is properly seeded.

This does not fully prevent against attacks weakening the entropy source.
An attacker who has control of the machine early in its boot sequence
could create the shared memory segment preventing detection of low entropy
conditions.  However, this is no worse than the current situation.

An attacker would also be capable of removing the shared memory segment
and causing seeding to reoccur resulting in a denial of service attack.
This is partially mitigated by keeping the shared memory alive for the
duration of the process's existence.  Thus, an attacker would not only need
to have called call shmctl(2) with the IPC_RMID command but the system
must subsequently enter a state where no instances of libcrypto exist in
any process.  Even one long running process will prevent this attack.

The System V shared memory calls used here go back at least as far as
Linux kernel 2.0.  Linux kernels 4.8 and later, don't have a reliable way
to detect that /dev/urandom has been properly seeded, so a failure is raised
for this case (i.e. the getentropy(2) call has already failed).

Untangle / retangle opensslv.h, openssslconf.h and macros.h

When openssl/macros.h is included without openssl/opensslv.h, it can't
define OPENSSL_API_4 properly (with sufficient warnings enabled, the
compiler will complain about OPENSSL_VERSION_MAJOR not being defined).
The quick fix could have been to include openssl/opensslv.h in
openssl/macros.h, but that would create a nasty include loop, since
openssl/opensslv.h includes openssl/opensslconf.h, which includes
openssl/macros.h, in an order that leads back to macro check errors.

The objective is to make these headers more independent:

- openssl/opensslconf.h should really be completely independent, as it
  only defines macros for configuration values.  However, it needs to
  include openssl/macros.h for backward compatibility reasons.  We do
  this at the very end, under inclusion guards.
- openssl/macros.h is changed to include openssl/opensslconf.h, so it
  gets necessary configuration values to build some macros.  This will
  not cause an endless inclusion loop, since opensslconf.h's inclusion
  of macros.h is under guard.
- openssl/opensslv.h is changed to include openssl/macros.h instead of
  openssl/opensslconf.h.

Only one last piece needs to be done to make openssl/macros.h
independent from openssl/opensslv.h.  We can realise that the
definition of OPENSSL_API_4 doesn't need to depend on the current
version number.  There's nothing in our configuration that  would have
OPENSSL_API_4 defined to 1, and if the user sets OPENSSL_API_COMPAT or
OPENSSL_API_LEVEL to a high enough value, we consider that a
deliberate and knowledgable action on their part.
