When parsing a combined structure pass a flag to the decode routine
so on error a pointer to the parent structure is not zeroed as
this will leak any additional components in the parent.

This can leak memory in any application parsing PKCS#7 or CMS structures.

CVE-2015-3195.

Thanks to Adam Langley (Google/BoringSSL) for discovering this bug using
libFuzzer.

The feature_test_macros(7) manual tells us that _BSD_SOURCE is
deprecated since glibc 2.20 and that the compiler will warn about it
being used, unless _DEFAULT_SOURCE is defined as well.

For all release branches.  It adds travis build support. If you don't
have a config file it uses the default (because we enabled travis for the
project), which uses ruby/rake/rakefiles, and you get confusing "build
still failing" messages.

In master we have the function OPENSSL_clear_free(x,y), which immediately
returns if x == NULL. In <=1.0.2 this function does not exist so we have to
do:
OPENSSL_cleanse(x, y);
OPENSSL_free(x);

However, previously, OPENSSL_cleanse did not check that if x == NULL, so
the real equivalent check would have to be:
if (x != NULL)
    OPENSSL_cleanse(x, y);
OPENSSL_free(x);

It would be easy to get this wrong during cherry-picking to other branches
and therefore, for safety, it is best to just ensure OPENSSL_cleanse also
checks for NULL.

Builds using no-tlsext in 1.0.0 and 0.9.8 are broken. This commit fixes the
issue. The same commit is applied to 1.0.1 and 1.0.2 branches for code
consistency. However this commit will not fix no-tlsext in those branches
which have always been broken for other reasons. The commit is not applied
to master at all, because no-tlsext has been completely removed from that
branch.

This file, when copied to .dir-locals.el in the OpenSSL source top,
will make sure that the CC mode style "OpenSSL-II" will be used for
all C files.

Additionally, I makes sure that tabs are never used as indentation
character, regardless of the emacs mode, and that the fill column is
78.
