f651c727f8 EVP: add name traversal functions to all fetchable types
The following new functions all do the same thing; they traverse
the set of names assigned to implementations of each algorithm type:

EVP_MD_names_do_all(), EVP_CIPHER_names_do_all(),
EVP_MAC_names_do_all(), EVP_KEYMGMT_names_do_all(),
EVP_KEYEXCH_names_do_all(), EVP_KDF_names_do_all(),
EVP_SIGNATURE_names_do_all()

We add a warning to the documentation of EVP_CIPHER_name() and
EVP_MD_name(), as they aren't suitable to use with multiple-name
implementation.

We also remove EVP_MAC_name() and evp_KDF_name(), as they serve no
useful purpose.

a07c17ef57 Add EVP_PKEY_CTX_new_provided()
This works as much as possible EVP_PKEY_CTX_new_id(), except it takes
data that's relevant for providers, algorithm name and property query
string instead of NID and engine.

Additionally, if EVP_PKEY_CTX_new() or EVP_PKEY_CTX_new_id() was
called, the algorithm name in the EVP_PKEY context will be set to the
short name of the given NID (explicit or the one of the given
EVP_PKEY), thereby giving an easier transition from legacy methods to
provided methods.

The intent is that operations will use this information to fetch
provider methods implicitly as needed.

c96399e296 Adapt EVP_CIPHER_{param_to_asn1,asn1_to_param} for use with provider.
So far, these two funtions have depended on legacy EVP_CIPHER
implementations to be able to do their work.  This change adapts them
to work with provided implementations as well, in one of two possible
ways:

1.  If the implementation's set_asn1_parameters or get_asn1_parameters
    function pointers are non-NULL, this is a legacy implementation,
    and that function is called.
2.  Otherwise, if the cipher doesn't have EVP_CIPH_FLAG_CUSTOM_ASN1
    set, the default AlgorithmIdentifier parameter code in libcrypto
    is executed.
3.  Otherwise, if the cipher is a provided implementation, the ASN1
    type structure is converted to a DER blob which is then passed to
    the implementation as a parameter (param_to_asn1) or the DER blob
    is retrieved from the implementation as a parameter and converted
    locally to a ASN1_TYPE (asn1_to_param).

With this, the old flag EVP_CIPH_FLAG_DEFAULT_ASN1 has become
irrelevant and is simply ignored.

d86167ec75 Add legacy include guards to public header files
For every public header file, the old include guard definition needs
to be added in addition to the new one

include/openssl/file.h:

    #ifndef OPENSSL_FILE_H
    # define OPENSSL_FILE_H
    # pragma once

    # include <openssl/macros.h>
    # if !OPENSSL_API_3
    #  define HEADER_FILE_H
    # endif
    ...

This is going to ensure that applications which use the old include guards
externally, for example like this

    #ifndef HEADER_FILE_H
    # include <openssl/file.h>
    #endif

will not fail to compile.

In addition to the legacy guard, the public header files also receive a
'# pragma once' directive.

706457b7bd Reorganize local header files
Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

  '*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

25f2138b0a Reorganize private crypto header files
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.

7cfa1717b8 Modify providers that keep track of underlying algorithms
With some provider implementations, there are underlying ciphers,
digests and macs.  For some of them, the name was retrieved from the
method, but since the methods do not store those any more, we add
different mechanics.

For code that needs to pass on the name of a cipher or diges via
parameters, we simply locally store the name that was used when
fetching said cipher or digest.  This will ensure that any underlying
code that needs to fetch that same cipher or digest does so with the
exact same name instead of any random name from the set of names
associated with the algorithm.

For code that needs to check what kind of algorithm was passed, we
provide EVP_{type}_is_a(), that returns true if the given method has
the given name as one of its names.

f7c16d48a9 In provider implemented methods, save the name number, not the name string
Multiple names per implementation is already supported in the namemap,
but hasn't been used yet.  However, as soon as we have multiple names,
we will get an issue with what name should be saved in the method.

The solution is to not save the name itself, but rather the number
it's associated with.  This number is supposed to be unique for each
set of names, and we assume that algorithm names are globally unique,
i.e. there can be no name overlap between different algorithm types.

Incidently, it was also found that the 'get' function used by
ossl_construct_method() doesn't need all the parameters it was given;
most of what it needs, it can now get through the data structure given
by the caller of ossl_construct_method().  As a consequence,
ossl_construct_method() itself doesn't need all the parameters it was
given either.

There are some added internal functions that are expected to disappear
as soon as legacy code is removed, such as evp_first_name() and
ossl_namemap_num2name().

b13342e933 Modernise the ERR functionality further (new functions and deprecations)
ERR_func_error_string() essentially returns NULL, and since all
function codes are now removed for all intents and purposes, this
function has fallen out of use and cannot be modified to suit the
data, since its only function is to interpret an error code.

To compensate for the loss of error code, we instead provide new
functions that extracts the function name strings from an error
record:

- ERR_get_error_func()
- ERR_peek_error_func()
- ERR_peek_last_error_func()

Similarly, the once all encompasing functions
ERR_peek_last_error_line_data(), ERR_peek_error_line_data() and
ERR_get_error_line_data() lack the capability of getting the function
name string, so we deprecate those and add these functions to replace
them:

- ERR_get_error_all()
- ERR_peek_error_all()
- ERR_peek_last_error_all()

Finally, we adjust a few lines of code that used the now deprecated
functions.

06ff79bd77 include/openssl/err.h: Depend on OPENSSL_NO_FILENAMES, not OPENSSL_NO_ERR
The configuration option 'no-err' is documented to be used to avoid
loading error related string tables.  For some reason, it was also
used to define if ERR_PUT_error() would pass the source file name and
line information or not.

The configuration option 'no-filenames' is documented to be used to
avoid passing the source file name and line anywhere.  So, the
definition of ERR_PUT_error() should depend on OPENSSL_NO_FILENAMES
rather than OPENSSL_NO_ERR.

Furthermore, the definition of OPENSSL_FILE and OPENSSL_LINE depends
on if OPENSSL_NO_FILENAMES is defined or not, so there was never any
need to do extra macro gymnastics in include/openssl/err.h, so we
simply remove it and use OPENSSL_FILE and OPENSSL_LINE directly.

Finally, the macro OPENSSL_FUNC is unaffected by all these
configuration options, so it should be used in all macros that call
ERR_set_debug().

0cd1b144f9 util/mkerr.pl: make it not depend on the function code
The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not.  Since this function returns
NULL always, this check became useless.

Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.

To top it off, we rebuild all affected C sources.

Fixes #9756

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.
