14b07a02a6 Harden ASN.1 BIO handling of large amounts of data. 
If the ASN.1 BIO is presented with a large length field read it in
chunks of increasing size checking for EOF on each read. This prevents
small files allocating excessive amounts of data.

CVE-2016-2109

Thanks to Brian Carpenter for reporting this issue.

(Imported from upstream's f32774087f7b3db1f789688368d16d917757421e)

57707c70dc OpenSSL reformat x509/, x509v3/, pem/ and asn1/. 
OpenSSL upstream did a bulk reformat. We still have some files that have
the old OpenSSL style and this makes applying patches to them more
manual, and thus more error-prone, than it should be.

This change is the result of running
  util/openssl-format-source -v -c .
in the enumerated directories. A few files were in BoringSSL style and
have not been touched.

This change should be formatting only; no semantic difference.

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/'

1a5c50f3a8 Error codes are uint32_t, not unsigned long. 
Fix a few remnants of them being unsigned long. Also rename extremely unhelpful
variable names in SSL_get_error. i is now ret_code to match the header.
