Remove reference to ERR_TXT_MALLOCED in the error library as that is
only used internally. Indicate that returned error data must not be
freed.

(cherry picked from commit 1abfa78a8ba714f7e47bd674db53dbe303cd1ce7)

Add function to retrieve the signature from a CMS_SignerInfo structure:
applications can then read or modify it.

This fixes problems in POD list formatting: extra or missing =back
sequences.

doc/ssl/SSL_CTX_set1_curves.pod around line 90: =back without =over
doc/ssl/SSL_CTX_set1_verify_cert_store.pod around line 73: =back without =over
doc/ssl/SSL_CTX_add1_chain_cert.pod around line 82: =back without =over
doc/crypto/evp.pod around line 40: '=item' outside of any '=over'
crypto/des/des.pod around line 184: You forgot a '=back' before '=head1'

PR#3147

PR#3071

The primary changes made are:
- Updates to the "NAME" section of many pages to correctly reflect the
functions defined on those pages. This section is automatically parsed
by the util/extract-names.pl script, so if it is not correct then
running "man" will not correctly locate the right manual pages.
- Updates to take account of where functions are now deprecated
- Full documentation of the ec sub-library
- A number of other typo corrections and other minor tweaks

Add CMS_RecipientInfo_encrypt: this function encrypts an existing content
encryption key to match the key in the RecipientInfo structure: this is
useful if a new recpient is added to and existing enveloped data structure.

Add documentation.

podlators 2.5.0 has switched to dying on POD syntax errors. This means
that a bunch of long-standing erroneous POD in the openssl documentation
now leads to fatal errors from pod2man, halting installation.

Unfortunately POD constraints mean that you have to sort numeric lists
in ascending order if they start with 1: you cannot do 1, 0, 2 even if
you want 1 to appear first. I've reshuffled such (alas, I wish there
were a better way but I don't know of one).
