Remove support for "old-style" X509V3_EXT_METHODs. I don't believe these codepaths have ever been run. All the built-in X509V3_EXT_METHODs are ASN1_ITEM-based, as are all callers I found of X509V3_EXT_add and X509V3_EXT_add_list. Also document not to use those APIs because they're pointless and (for now) not even thread-safe. Making them thread-safe is doable, but it'd add rwlock contention in certificate verification, unless we first rework certificate verification to ignore custom registrations, because it never uses them anyway. But that only proves that this whole feature was pointless, so this time may be better spent trying to get rid of this API. Update-Note: Externally-installed X509V3_EXT_METHODs now must be ASN1_ITEM-based. I believe all existing ones already are. If there are any that aren't, let us know. We'll either revert this for now, or export a way to implement custom ASN1_ITEMs, or, most likely, try to move the caller off custom X509V3_EXT_METHODs altogether. Like most of OpenSSL's other global registration APIs, this one is unsafe (two callers may conflict) and there isn't much reason to register it with the library because OpenSSL doesn't do much with the registration anyway.

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.
