382bc29251 Defensively avoid assuming d2i functions don't advance on error. 
Although the previous commit should ensure this doesn't happen, the
uint8_t** pattern is very error-prone and we're trying to avoid doing
much to the legacy ASN.1 stack. To that end, maintaining the strong
exception guarantee w.r.t. the input pointer-pointer is best effort and
we won't rely on it, so we needn't spend our time chasing down problems.

15e4deb165 d2i: don't update input pointer on failure 
(Imported from upstream's 728bcd59d3d41e152aead0d15acc51a8958536d3.)

Actually this one was reported by us, but the commit message doesn't
mention this.

This is slightly modified from upstream's version to fix some problems
noticed in import. Specifically one of d2i_X509_AUX's success paths is
bust and d2i_PrivateKey still updates on one error path. Resolve the
latter by changing both it and d2i_AutoPrivateKey to explicitly hit the
error path on ret == NULL. This lets us remove the NULL check in
d2i_AutoPrivateKey.

We'll want to report the problems back upstream.

3570d73bf1 Remove the func parameter to OPENSSL_PUT_ERROR. 
Much of this was done automatically with
  find . -name '*.c' | xargs sed -E -i '' -e 's/(OPENSSL_PUT_ERROR\([a-zA-Z_0-9]+, )[a-zA-Z_0-9]+, ([a-zA-Z_0-9]+\);)/\1\2/'
  find . -name '*.c' | xargs sed -E -i '' -e 's/(OPENSSL_PUT_ERROR\([a-zA-Z_0-9]+, )[a-zA-Z_0-9]+,  ([a-zA-Z_0-9]+\);)/\1\2/'

7f15ff53d8 Rename crypto/{bn,evp}/asn1.c. 
gyp doesn't allow two files to share the same name to avoid bugs in OS X
libtool, so asn1.c's need to all get a prefix.
