Subject: [PATCH] Refactor OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA

This refactors OSSL_LIB_CTX to avoid using CRYPTO_EX_DATA. The assorted
objects to be managed by OSSL_LIB_CTX are hardcoded and are initialized
eagerly rather than lazily, which avoids the need for locking on access
in most cases.

Fixes #17116.

 =head1 DESCRIPTION
 
-Internally, the OpenSSL library context B<OSSL_LIB_CTX> is implemented
-as a B<CRYPTO_EX_DATA>, which allows data from diverse parts of the
-library to be added and removed dynamically.
-Each such data item must have a corresponding CRYPTO_EX_DATA index
-associated with it. Unlike normal CRYPTO_EX_DATA objects we use static indexes
-to identify data items. These are mapped transparently to CRYPTO_EX_DATA dynamic
-indexes internally to the implementation.
-See the example further down to see how that's done.
-
-ossl_lib_ctx_get_data() is used to retrieve a pointer to the data in
-the library context I<ctx> associated with the given I<index>. An
-OSSL_LIB_CTX_METHOD must be defined and given in the I<meth> parameter. The index
-for it should be defined in cryptlib.h. The functions through the method are
-used to create or free items that are stored at that index whenever a library
-context is created or freed, meaning that the code that use a data item of that
-index doesn't have to worry about that, just use the data available.
-
-Deallocation of an index happens automatically when the library
-context is freed.
-
-ossl_lib_ctx_run_once is used to run some initialisation routine I<run_once_fn>
+ossl_lib_ctx_run_once() is used to run some initialisation routine I<run_once_fn>
 exactly once per library context I<ctx> object. Each initialisation routine
 should be allocate a unique run once index in cryptlib.h.
 
 Any resources allocated via a run once initialisation routine can be cleaned up

-
-For a type C<FOO> that should end up in the OpenSSL library context, a
