Write new manual pages PKCS12_new(3) and PKCS12_SAFEBAG_new(3) from

scratch.  All these functions are listed in <openssl/pkcs12.h> and
in OpenSSL doc/man3/X509_dup.pod.  As usual, OpenSSL documentation
specifies the wrong header file.

Note that PKCS#12 documentation is still scanty at best.
For example, out of 19 public functions handling PKCS12 objects,
five are now documented, and this commit documents the first two
out of 24 public functions handling PKCS12_SAFEBAG objects.
