Change the logic and behaviour surrounding '--api' and 'no-deprecated'

At some point in time, there was a 'no-deprecated' configuration
option, which had the effect of hiding all declarations of deprecated
stuff, i.e. make the public API look like they were all removed.

API compatibility level.

At some later point in time, '--api' was changed to mean the same as
'no-deprecated', but only for the deprecations up to and including the
desired API compatibility level.  BN_zero() has been set to the
pre-1.0.0 implementation ever since, unless 'no-deprecation' has been
given.

This change turns these options back to their original meaning, but
with the slight twist that when combined, i.e. both '--api' and
'no-deprecated' is given, the declarations that are marked deprecated
up to an including the desired API compatibility level are hidden,
simulating that they have been removed.

If no desired API compatibility level has been given, then
configuration sets the current OpenSSL version by default.

Furthermore, the macro OPENSSL_API_LEVEL is now used exclusively to
check what API compatibility level is desired.  For checking in code
if `no-deprecated` has been configured for the desired API
compatibility level, macros for each supported level is generated,
such as OPENSSL_NO_DEPRECATED_1_1_1, corresponding to the use of
DEPRECATEDIN_ macros, such as DEPRECATEDIN_1_1_1().

Just like before, to set an API compatibility level when building an
application, define OPENSSL_API_COMPAT with an appropriate value.  If
it's desirable to hide deprecated functions up to and including that
level, additionally define OPENSSL_NO_DEPRECATED (the value is
ignored).

util/*.num: deassign ordinal numbers from new symbols

Symbols that have appeared since 1.1.1 was released are considered
unassigned in the development branch.   This is marked by having a
question mark as its ordinal number.

This introduces two new markers to be used instead of ordinal numbers:

    ?   signifying it gets the previous symbol's number plus one
    ?+  signifying it gets the same number as the previous symbol

'?+' should remain rare, but is useful to create aliases when needed
(for example when two different symbols clash because they only differ
in character case, see include/openssl/symhacks.h)

The intention is that a development branch won't have set numbers for
new symbols, and that the final numbers will only get allocated when
making beta or final releases.
