SSLsplit was directly accessing `extra_certs` within `SSL_CTX` to get to
the extra certificates chain. When building on OpenSSL 1.0.2 or newer,
use the new API instead of directly accessing `extra_certs`.
Issue: #79
If the proper headers matching either the reported XNU version or OS X
version exactly cannot be found, use the latest headers that SSLsplit
knows about. This fixes build on new releases of OS X that have no
source code published by Apple yet.
This fixes the following make error on Mac OS X versions that we don't
explicitly support yet due to missing sources:
GNUmakefile:55: *** unterminated call to function `shell': missing `)'.
Stop.

Apple checks EUID==0 on ioctl(/dev/pf), whereas OpenBSD and FreeBSD only
check permissions on open(/dev/pf). This means that on OS X, it is not
possible to open /dev/pf, drop privileges, and send an ioctl to the file
descriptor opened earlier with EUID==0. It also means Apple broke the
Unix way of dealing with device nodes - why are there file permissions
on /dev/pf when they later enforce EUID==0 on use, thereby breaking
basic Unix mechanisms? Work around this by disallowing -u with pf
proxyspecs and by not automatically dropping to nobody on Mac OS X.

On some platforms, sysconf(_SC_GETPW_R_SIZE_MAX) compiles but never
succeeds (e.g. FreeBSD 8.4). Fix this by dynamically enlarging an
initially small buffer until it is large enough, and reuse the
determined buffer size on subsequent calls to the same function.
OpenSSL 0.9.8y also crashes in OpenSSL's SSL_get_certificate() on a
NULL pointer dereference. Fix by also using the direct access hack
developed for OpenSSL 1.0.0k and 1.0.1e with OpenSSL 0.9.8y.
