Make ERR and thread use system malloc.

This will let us call ERR and thread_local from OPENSSL_malloc
without creating a circular dependency. We also make
ERR_get_error_line_data add ERR_FLAG_MALLOCED to the returned
flags value, since some projects appear to be making
assumptions about it being there.

Bug: 564

Update-Note: Any recent documentation (in all OpenSSL forks) for the ERR functions
cautions against freeing the returned ERR "data" strings, as freeing them is handled
by the error library. This change can make an existing double free bug more
obvious by being more likely to cause a crash with the double free.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
