openssl/ssl.h: restore some renamed public SSL_CTRL defines

Fixes #6022

In commit de4d764e3271, the following SSL_CTRL #define's where renamed

    SSL_CTRL_GET_CURVES        ->  SSL_CTRL_GET_GROUPS
    SSL_CTRL_SET_CURVES        ->  SSL_CTRL_SET_GROUPS
    SSL_CTRL_SET_CURVES_LIST   ->  SSL_CTRL_SET_GROUPS_LIST
    SSL_CTRL_GET_SHARED_CURVE  ->  SSL_CTRL_GET_SHARED_GROUP

The corresponding function-like macros (e.g, SSL_get1_curves(ctx, s)) were
renamed, too, and compatibility #define's were added. This was overlooked for
the above constants. Since the constants are part of the public interface,
they must not be removed for a minor release.

As a consequence the Qt5 configure check (and the build) fails.

DRBG: implement a get_nonce() callback

Fixes #5849

In pull request #5503 a fallback was added which adds a random nonce of
security_strength/2 bits if no nonce callback is provided. This change raised
the entropy requirements form 256 to 384 bit, which can cause problems on some
platforms (e.g. VMS, see issue #5849).

The requirements for the nonce are given in section 8.6.7 of NIST SP 800-90Ar1:

  A nonce may be required in the construction of a seed during instantiation
  in order to provide a security cushion to block certain attacks.
  The nonce shall be either:

  a) A value with at least (security_strength/2) bits of entropy, or

  b) A value that is expected to repeat no more often than a
     (security_strength/2)-bit random string would be expected to repeat.

  Each nonce shall be unique to the cryptographic module in which instantiation
  is performed, but need not be secret. When used, the nonce shall be considered
  to be a critical security parameter.

This commit implements a nonce of type b) in order to lower the entropy
requirements during instantiation back to 256 bits.

The formulation "shall be unique to the cryptographic module" above implies
that the nonce needs to be unique among (with high probability) among all
DRBG instances in "space" and "time". We try to achieve this goal by creating a
nonce of the following form

    nonce = app-specific-data || high-resolution-utc-timestamp || counter

Where || denotes concatenation. The application specific data can be something
like the process or group id of the application. A utc timestamp is used because
it increases monotonically, provided the system time is synchronized. This approach
may not be perfect yet for a FIPS evaluation, but it should be good enough for the
moment.

This commit also harmonizes the implementation of the get_nonce() and the
get_additional_data() callbacks and moves the platform specific parts from
rand_lib.c into rand_unix.c, rand_win.c, and rand_vms.c.

The scrypt and RSA-PSS documents were a mixture of section 3 and
section 7 material.  With pre-1.1.1 OpenSSL, this is understandable,
since we had a different directory layout.  With 1.1.1, we've moved to
the typical man-page directory layout, and the documents need to be
updated accordingly.

Also, the scrypt document contained a description of
EVP_PKEY_CTX_set1_pbe_pass(), which is a generic function rather than
an scrypt specific function, and therefore should be documented
separately.

Add a test for SRP

Reviewed-by: Andy Polyakov <appro@openssl.org>
(Merged from https://github.com/openssl/openssl/pull/5925)

Add support for the SRP base64 alphabet

Historically we used to implement standalone base64 code for SRP. This
was replaced by commit 3d3f21aa with the standard base64 processing code.

However, the SRP base64 code was designed to be compatible with other SRP
libraries (notably libsrp, but also others) that use a variant of standard
base64. Specifically a different alphabet is used and no padding '='
characters are used. Instead 0 padding is added to the front of the string.
By changing to standard base64 we change the behaviour of the API which may
impact interoperability. It also means that SRP verifier files created prior
to 1.1.1 would not be readable in 1.1.1 and vice versa.

Instead we expand our standard base64 processing with the capability to be
able to read and generate the SRP base64 variant.

Change SRP functions to use EVP_EncodeUpdate/EVP_DecodeUpdate functions

Previously they were using EVP_EncodeBlock/EVP_DecodeBlock. These are low
level functions that do not handle padding characters. This was causing
the SRP code to fail. One side effect of using EVP_EncodeUpdate is that
it inserts newlines which is not what we need in SRP so we add a flag to
avoid that.

Configuration: Simplify generating list of generated files in build file templates

Computing the value of the GENERATED variable in the build file
templates is somewhat overcomplicated, and because of possible
duplication errors, changes are potentially error prone.

Looking more closely at how this list is determined, it can be
observed that the exact list of files to check is consistently
available in all the values found in the %unified_info tables
'depends', 'sources' and 'shared_sources', and all that's needed is to
filter those values so only those present as keys in the 'generate'
table are left.

This computation is also common for all build files, so due to its
apparent complexity, we move it to common0.tmpl, with the result left
in a global variable (@generated), to be consumed by all build file
templates.

common0.tmpl is included among the files to process when creating
build files, but unlike common.tmpl, it comes first of all.

Fix false positives of IS_*() macros for 8-bit ASCII characters

Fixes #5778, #5840

The various IS_*() macros did not work correctly for 8-bit ASCII
characters with the high bit set, because the CVT(a) preprocessor
macro and'ed the given ASCII value with 0x7F, effectively folding
the high value range 128-255 over the low value range 0-127.
As a consequence, some of the IS_*() erroneously returned TRUE.

This commit fixes the issue by adding range checks instead of
cutting off high order bits using a mask. In order avoid multiple
evaluation of macro arguments, most of the implementation was moved
from macros into a static function is_keytype().
