Private hstrerror was introduced to address linking problem on HP-UX,
but truth be told conemporary systems, HP-UX included, wouldn't come
to that call, they would use getaddrinfo and gai_strerror, while
gethostbyname and h_errno are there to serve legacy systems. Since
legacy systems are naturally disappearing breed, we can as well just
let user interpret number.

With VMS C, the second parameter takes a 32-bit pointer.  When
building with 64-bit pointer size default, we must compensate.

- FLAT_INC
- PKCS1_CHECK (the SSL_OP_PKCS1_CHECK options have been
  no-oped)
- PKCS_TESTVECT (debugging leftovers)
- SSL_AD_MISSING_SRP_USERNAME (unfinished feature)
- DTLS_AD_MISSING_HANDSHAKE_MESSAGE (unfinished feature)
- USE_OBJ_MAC (note this removes a define from the public header but
   very unlikely someone would be depending on it)
- SSL_FORBID_ENULL

It's undocumented and unused in the tree.  The idea seems to have
never gained much traction, and can be removed without breaking
ABI compatibility.

Cleanse instead, and free in the free routine.

Seems to have been introduced in commit
846ec07d when EVP_CIPHER_CTX was made
opaque.

Base address setting was done for the sake of FIPS.  Since FIPS references
have been removed, we clean away this one as well.

AGL has a history of pointing out the idiosynchronies/laxness of the
openssl PEM parser in amusing ways.  If we want this functionality to
stay present, we should test that it works.

Generate a fresh certificate and DSA private key in their respective PEM
files.  Modify the resulting ASCII in various ways so as to produce input
files that might be generated by non-openssl programs (openssl always
generates "standard" PEM files, with base64 data in 64-character lines
except for a possible shorter last line).

Exercise various combinations of line lengths, leading/trailing
whitespace, non-base64 characters, comments, and padding, for both
unencrypted and encrypted files.  (We do not have any other test coverage
that uses encrypted files, as far as I can see, and the parser enforces
different rules for the body of encrypted files.)

Add a recipe to parse these test files and verify that they contain the
expected string or are rejected, according to the expected status.
Some of the current behavior is perhaps suboptimal and could be revisited.
