* Add a new interface, OPENSSL_cpu_caps(), to return the currently runningmiod2015-09-132-2/+17
| | | | | | | | | | | | | cpu's specific hardware capabilities users of libcrypto might be interested in, as an integer value. This deprecates the existing OPENSSL_ia32cap() macro and the OPENSSL_ia32cap_loc() function (which returns the pointer so that you can mess with stuff you shouldn't mess with). Interpreting the value returned by OPENSSL_cpu_caps() is, of course, machine-dependent. Minor version bump for libcrypto. ok beck@ jsing@
* The *_accept() functions increment in_handshake at the start of the function,jsing2015-09-134-38/+60
| | | | | | | | then decrement it and call a callback on exit from the function. As such, these functions should not return in the middle, otherwise in_handshake is never decremented and the callback never called. ok beck@ "with many sighs" miod@
* If we have hardware acceleration for AES, prefer AES as a symmetric cipherjsing2015-09-132-14/+60

* Split ssl3_send_client_key_exchange() (387 lines of code) into fivejsing2015-09-122-654/+702
| | | | | | | | | functions. The original was written as a huge if/else if chain - split out the handling for each key exchange type. This allows us to reduce two levels of indentation, make the code far more readable and have single return paths so that we can simplify clean up. ok beck@

| | | | | | | | ssl3_send_client_key_exchange() is effectively identical, in fact it has a number of bug fixes and improvements that never got merged into the DTLS copy of the code. Flenses another 264 lines of code. ok beck@

| | | | | | | | | | | | only define them if not building for the "openbsd" flavour. This way, non-obfuscated output can still be generated for analysis, by using the "openbsd" flavour (which OpenBSD HEAD will do), and obfuscated output, compatible with older as(1), will be generated for other platforms. The portable version of LibreSSL can then use "openbsd-portable" as the flavour for OpenBSD/amd64 so that generated files can be compiled with OpenBSD 5.7 and other older versions stuck with as(1) 2.15.

Thanks for Georgi Guninski (guninski at guninski dot com) for mentioning the possibility of a weak (non prime) q value and providing a test case.
