b484c6268c Disable atomic refcounts with no-threads
This is needed for building with '-march=i386 no-threads', on platforms
where libatomic is not available (djgpp, specifically).  The
implementation now falls back to 'CRYPTO_atomic_add()', which performs
plain lock-free addition in a 'no-threads' build.

a935791d54 Rework and make DEBUG macros consistent.
Remove unused -DCONF_DEBUG and -DBN_CTX_DEBUG.

Rename REF_PRINT to REF_DEBUG for consistency, and add a new
tracing category and use it for printing reference counts.

Rename -DDEBUG_UNUSED to -DUNUSED_RESULT_DEBUG

Fix BN_DEBUG_RAND so it compiles and, when set, force DEBUG_RAND to
be set also.

Rename engine_debug_ref to be ENGINE_REF_PRINT also for consistency.

Fixes #15357

fce56f5b69 REF_PRINT: cast pointer to void to avoid warnings
Currently, when configuring OpenSSL and specifying the --strict-warnings
option there are failures like the following one:

crypto/bio/bio_lib.c: In function 'BIO_up_ref':
include/internal/refcount.h:169:25: error: format '%p' expects argument
of type 'void *', but argument 3 has type 'BIO *'

      |                           void *
cc1: all warnings being treated as errors

This commit adds casts to avoid the warnings.

ae4186b004 Fix header file include guard names
Make the include guards consistent by renaming them systematically according
to the naming conventions below

For the public header files (in the 'include/openssl' directory), the guard
names try to match the path specified in the include directives, with
all letters converted to upper case and '/' and '.' replaced by '_'. For the
private header files files, an extra 'OSSL_' is added as prefix.

503d4745a1 internal/refcount.h: allow non-atomic build
Configure with -DOPENSSL_DEV_NO_ATOMICS and you get refcount without
atomics.  This is intended for internal development only, to check the
refcounting is properly coded.  It should never become a configuration
option, hence the name of the macro.

96d7852cbd internal/refcount.h: overhaul fencing and add _MSC_VER section.
Relax memory_order on counter decrement itself, because mutable
members of the reference-counted structure should be visible on all
processors independently on counter. [Even re-format and minimize
dependency on other headers.]
