fbb82a60dc Move peer chain security checks into x509_vfy.c
A new X509_VERIFY_PARAM_set_auth_level() function sets the
authentication security level.  For verification of SSL peers, this
is automatically set from the SSL security level.  Otherwise, for
now, the authentication security level remains at (effectively) 0
by default.

The new "-auth_level" verify(1) option is available in all the
command-line tools that support the standard verify(1) options.

New verify(1) tests added to check enforcement of chain signature
and public key security levels.  Also added new tests of enforcement
of the verify_depth limit.

Updated documentation.

where /tmp/pl is the following three-line script:
        print unless $. == 1 && m@/\* .*\.[ch] \*/@;

And then some hand-editing of other files.

a0724ef1c9 Better handling of verify param id peername field
Initialize pointers in param id by the book (explicit NULL assignment,
rather than just memset 0).

In x509_verify_param_zero() set peername to NULL after freeing it.

In x509_vfy.c's internal check_hosts(), avoid potential leak of
possibly already non-NULL peername.  This is only set when a check
succeeds, so don't need to do this repeatedly in the loop.

b4faea50c3 Use safer sizeof variant in malloc
For a local variable:
        TYPE *p;
Allocations like this are "risky":
        p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption.  Instead do this:
        p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.
