If there's a failure allocating md_data, the destination pctx will have
a shared pointer with the source EVP_MD_CTX, which will lead to problems
when either the source or the destination is freed.

If DSA parameters are absent return -1 (for unknown) in DSA_security_bits.
If parameters are absent when a certificate is set in an SSL/SSL_CTX
structure this will reject the certificate by default. This will cause DSA
certificates which omit parameters to be rejected but that is never (?)
done in practice.
Thanks to Brian 'geeknik' Carpenter for reporting this issue.

When it's the last item that is removed int_thread_hash == hash and we would
still call int_thread_release(&hash) while hash is already freed. So
int_thread_release would compare that dangling pointer to NULL which is
undefined behaviour. Instead do already what int_thread_release() would do,
and make the call do nothing instead.

Rename to OPENSSL_mem_debug_{push,pop}.
Remove simple calls; keep only calls used in recursive functions.
Ensure we always push, to simplify so that we can always pop

Just like *_clear_free routines. Previously undocumented, used

New functions EC_POINT_point2buf and EC_KEY_key2buf which encode
a point and allocate a buffer in one call.
New function EC_KEY_oct2key() which sets public key in an EC_KEY
structure from an encoded point.

Solaris builds were failing during async compilation because the .o files
created from compiling the corresponding .c files held in async/arch were
ending up in the top level async directory. Consequently the link fails
because it can't find the .o files.
Thanks to Richard Levitte for pointing me in the right direction on this.

Make EVP_PKEY_copy_parameters() work if the destination has no type
(e.g. if obtained from EVP_PKEY_new()) or the underlying key is NULL.
This is useful where we want to copy the parameters from an existing
key to a new key.

Commit 2b0180c37fa6ffc48ee40caa831ca398b828e680 attempted to do this but
only hit one of many BN_mod_exp codepaths. Fix remaining variants and add
a test for each method.
