Shane Lontis 90a1f2d76f Add libctx support to PKCS7.
-Public PKCS7 methods that create a PKCS7 object now have variants that also add a libctx and propq.
 This includes PKCS7_new_with_libctx(), PKCS7_sign_with_libctx() and PKCS7_encrypt_with_libctx()
-Added SMIME_read_PKCS7_ex() so that a created PKCS7 object can be passed to the read.
-d2i_PKCS7_bio() has been modified so that after it loads the PKCS7 object it then resolves any subobjects that require
 the libctx/propq (such as objects containing X509 certificates).

- ASN1 object utilities
=head1 SYNOPSIS
=for openssl generic
#include <openssl/asn1t.h>
DECLARE_ASN1_FUNCTIONS(type)
IMPLEMENT_ASN1_FUNCTIONS(stname)
typedef struct ASN1_ITEM_st ASN1_ITEM;
extern const ASN1_ITEM TYPE_it;
TYPE *TYPE_new(void);
TYPE *TYPE_dup(const TYPE *a);
void TYPE_free(TYPE *a);
int TYPE_print_ctx(BIO *out, TYPE *a, int indent, const ASN1_PCTX *pctx);
=head1 DESCRIPTION
In the description below, B<I<TYPE>> is used
as a placeholder for any of the OpenSSL datatypes, such as B<X509>.
The OpenSSL ASN1 parsing library templates are like a data-driven bytecode
interpreter.
Every ASN1 object as a global variable, TYPE_it, that describes the item
such as its fields. (On systems which cannot export variables from shared
libraries, the global is instead a function which returns a pointer to a
static variable.
The macro DECLARE_ASN1_FUNCTIONS() is typically used in header files
to generate the function declarations.
The macro IMPLEMENT_ASN1_FUNCTIONS() is used once in a source file
to generate the function bodies.
B<I<TYPE>_new>() allocates an empty object of the indicated type.
The object returned must be released by calling B<I<TYPE>_free>().
B<I<TYPE>_new_with_libctx>() is similiar to B<I<TYPE>_new>() but also passes the
library context I<libctx> and the property query I<propq> to use when retrieving
algorithms from providers.
B<I<TYPE>_dup>() copies an existing object, leaving it untouched.
B<I<TYPE>_free>() releases the object and all pointers and sub-objects
within it.
B<I<TYPE>_print_ctx>() prints the object I<a> on the specified BIO I<out>.
Each line will be prefixed with I<indent> spaces.
The I<pctx> specifies the printing context and is for internal
use; use NULL to get the default behavior. If a print function is
user-defined, then pass in any I<pctx> down to any nested calls.
=head1 RETURN VALUES
B<I<TYPE>_new>(), B<I<TYPE>_new_ex>() and B<I<TYPE>_dup>() return a pointer to
the object or NULL on failure.
B<I<TYPE>_print_ctx>() returns 1 on success or zero on failure.
=head1 HISTORY
The functions PKCS7_new_with_libctx() and CMS_ContentInfo_new_with_libctx() were
added in OpenSSL 3.0.
