issue-21718: remove setting of PTHREAD_MUTEX_NORMAL
issue: https://github.com/openssl/openssl/issues/21718

build break reported:
crypto/threads_pthread.c:76:5: warning: implicit declaration of function 'pthread_mutexattr_settype'; did you mean 'pthread_mutexattr_destroy'? [-Wimplicit-function-declaration]
   76 |     pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL);
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~
      |     pthread_mutexattr_destroy
crypto/threads_pthread.c:76:38: error: 'PTHREAD_MUTEX_NORMAL' undeclared (first use in this function); did you mean 'PTHREAD_MUTEX_TIMED_NP'?
   76 |     pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL);
      |                                      ^~~~~~~~~~~~~~~~~~~~
      |                                      PTHREAD_MUTEX_TIMED_NP

This occurs because PTHREAD_MUTEX_NORMAL is only defined in glibc if
__USE_UNIX98 or __USE_XOPEN2K8 is defined, which is derived from setting
__USE_POSIX_C_SOURCE or __XOPEN_SOURCE is selected in the glibc feature
set for a build.  Since openssl selects no specific feature set from
glibc, the build break occurs

We could select a feature set of course, but that seems like a
significant discussion to have prior to doing so. Instead, the simpler
solution is to just not set the mutex type at all, given that
pthread_mutexattr_init sets the default mutex type, which should be akin
to normal anyway (i.e. no mutex error checking or allowed-recursive
behavior)

Kirill A. Korinsky 22eb386384 Never use `__atomic_*` on macOS 10.7 and 10.8
macOS 10.7 and 10.8 had a bit wired clang which is detected as
`__GNUC__` which has `__ATOMIC_ACQ_REL` but it excepts one option at
`__atomic_is_lock_free` instead of 2.

This prevents OpenSSL to be compiled on such systems.

Matt Caswell ef59d8ab23 Some platforms don't have pthread_atfork
We've had a report of a linker failure on some platforms (this one was
linux ARM) that apparently did not have pthread_atfork. It's strange that
this has not been reported before but the simplest solution is just to
remove this from the library since it isn't really used anyway.

Currently it is called to set up the fork handlers OPENSSL_fork_prepare,
OPENSSL_fork_parent and OPENSSL_fork_child. However all of those functions
are no-ops. This is a remnant from earlier code that got removed. We can
safely remove it now.

Matt Caswell c739222b5a Fix no-threads
Make OPENSSL_fork_prepare() et al always available even in a no-threads
build. These functions are no-ops anyway so this shouldn't make any
difference.

This fixes an issue where the symbol_presence test fails in a no-threads
build. This is because these functions have not been marked in
libcrypto.num as being dependent on thread support. Enclosing the
declarations of the functions in the header with an appropriate guard
does not help because we never define OPENSSL_NO_THREADS (we define the
opposite OPENSSL_THREADS). This confuses the scripts which only consider
OPENSSL_NO_* guards. The simplest solution is to just make them always
available.

Dr. Matthias St. Pierre 849529257c drbg: ensure fork-safety without using a pthread_atfork handler
When the new OpenSSL CSPRNG was introduced in version 1.1.1,
it was announced in the release notes that it would be fork-safe,
which the old CSPRNG hadn't been.

The fork-safety was implemented using a fork count, which was
incremented by a pthread_atfork handler. Initially, this handler
was enabled by default. Unfortunately, the default behaviour
had to be changed for other reasons in commit b5319bdbd0, so
the new OpenSSL CSPRNG failed to keep its promise.

This commit restores the fork-safety using a different approach.
It replaces the fork count by a fork id, which coincides with
the process id on UNIX-like operating systems and is zero on other
operating systems. It is used to detect when an automatic reseed
after a fork is necessary.

To prevent a future regression, it also adds a test to verify that
the child reseeds after fork.

Andy Polyakov d2b863643d crypto/threads_*: remove CRYPTO_atomic_{read|write}.
CRYPTO_atomic_read was added with intention to read statistics counters,
but readings are effectively indistinguishable from regular load (even
in non-lock-free case). This is because you can get out-dated value in
both cases. CRYPTO_atomic_write was added for symmetry and was never used.

In case of missing pthread_rwlock_t implementation CRYPTO_RWLOCK will work as exclusive lock in write-only mode of pthread_rwlock_t lock.

The implementation based on pthread_mutex_t must be using PTHREAD_MUTEX_RECURSIVE mode to be compatible with recursive behavior of pthread_rwlock_rdlock.
