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.

c18d2d94c8 Funtion name with variable part in doc/man7/ and doc/internal/man3/
We have a few pages where part of function names can be considered
variable.  There are no normative guidelines for such a case, but if
we draw from the formatting convention of variable and argument names,
we can draw the conclusion that this variable part should be italized,
within already given conventions.  In other words, we need to help the
POD processor along in cases like these:

    SPARSE_ARRAY_OF(TYPE)
    ossl_sa_TYPE_num()

These need explicit formatting:

    B<SPARSE_ARRAY_OF>(I<TYPE>)
    B<ossl_sa_I<TYPE>_num>()

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().

3ca9d210c9 Refactor how KEYMGMT methods get associated with other methods
KEYMGMT methods were attached to other methods after those were fully
created and registered, thereby creating a potential data race, if two
threads tried to create the exact same method at the same time.

Instead of this, we change the method creating function to take an
extra data parameter, passed all the way from the public fetching
function.  In the case of EVP_KEYEXCH, we pass all the necessary data
that evp_keyexch_from_dispatch() needs to be able to fetch the
appropriate KEYMGMT method on the fly.

If ossl_method_store_add() gets called with a method that already exists

e74bd29053 Prepare EVP_MAC infrastructure for moving all MACs to providers
Quite a few adaptations are needed, most prominently the added code
to allow provider based MACs.

As part of this, all the old information functions are gone, except
for EVP_MAC_name().  Some of them will reappear later, for example
EVP_MAC_do_all() in some form.

MACs by EVP_PKEY was particularly difficult to deal with, as they
need to allocate and deallocate EVP_MAC_CTXs "under the hood", and
thereby implicitly fetch the corresponding EVP_MAC.  This means that
EVP_MACs can't be constant in a EVP_MAC_CTX, as their reference count
may need to be incremented and decremented as part of the allocation
or deallocation of the EVP_MAC_CTX.  It may be that other provider
based EVP operation types may need to be handled in a similar manner.

36f5ec55e6 Add functions to see if a provider is available for use.
Public function OSSL_PROVIDER_available() takes a library context and
a provider name, and returns 1 if it's available for use, i.e. if it's
possible to fetch implementations from it, otherwise 0.

Internal function ossl_provider_activated() returns 1 if the given
OSSL_PROVIDER is activated, otherwise 0.

To make this possible, the activation of fallbacks got refactored out
to a separate function, which ended up simplifying the code.

If a legacy lower level key has been assigned to the EVP_PKEY, we use

between old style public key types and the EVP_PKEY on providers.

If successful, this function returns a reference to the appropriate

to do this mapping. For providers linking against libcrypto the new function
just wraps OBJ_nid2sn(). For the FIPS provider it has a look up for all the
NIDs known there.
