We don't want to hold a read lock when calling a user supplied callback.
That callback could do anything so the risk of a deadlock is high.
Instead we collect all the names first inside the read lock, and then
subsequently call the user callback outside the read lock.

EVP_CIPHER already caches certain constants so that we don't have to
query the provider every time. We do the same thing with EVP_MD constants.
Without this we can get performance issues, e.g. running "speed" with
small blocks of data to digest can spend a long time in EVP_MD_size(),
which should be quick.

Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,

The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

Prior to OpenSSL 3.0 calling EVP_DigestInit_ex() on an mdctx previously

Instead of sometimes, and sometimes not reporting an error in the
caller of EVP_XXX_fetch(), where the error may or may not be very
accurate, it's now centralised to the inner EVP fetch functionality.
It's made in such a way that it can determine if an error occured
because the algorithm in question is not there, or if something else
went wrong, and will report EVP_R_UNSUPPORTED_ALGORITHM for the
former, and EVP_R_FETCH_FAILED for the latter.
This helps our own test/evp_test.c when it tries to figure out why an
EVP_PKEY it tried to load failed to do so.

Prior to OpenSSL 3.0 EVP_Digest[Sign|Verify|Update were just macros for
EVP_DigestUpdate. They are now separate functions. Unfortunately some
code assumes that EVP_Digest[Sign|Verify]Update is interchangeable with
EVP_DigestUpdate. For example the dgst app uses an MD bio which always
calls EVP_DigestUpdate(). However the dgst app supports signing instead
of digesting and may initialise with EVP_DigestSignInit_ex() instead of
just EVP_DigestInit().
We now detect these differences and redirect to the correct function
where appropriate.

EVP_DigestInit_ex forced following of the legacy path if ctx->pctx is
set (meaning we've actually been called via EVP_DigestSignInit_ex).
There is some code in the legacy path that calls the
EVP_PKEY_CTRL_DIGESTINIT ctrl on the pctx. Not going down the legacy path
if ctx->pctx is set means that ctrl message will neve get sent. However,
it turns out that all algs that understand that ctrl also set the
EVP_MD_CTX_FLAG_NO_INIT flag which forces legacy anyway. Therefore the
ctx->pctx check is not required and can be removed.

Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:
While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.
To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:
#include "internal/file.h" # located in 'include/internal'
#include "internal/file_int.h" # located in 'crypto/include/internal'
This commit moves the private crypto headers from
'crypto/include/internal' to 'include/crypto'
As a result, the include directives become unambiguous
#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'
hence the superfluous '_int.h' suffixes can be stripped.
The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.
