This change adds the AES-128-CBC-SHA and AES-256-CBC-SHA AEADs to the
speed test. These AEADs need an 11 byte additional data so the test is
extended to be able to provide that.

This eliminates a source of variability from the benchmarks.

This change adds the stitched RC4-MD5 code from upstream OpenSSL but
exposes it as an AEAD. It's not a normal AEAD (it's stateful thus
doesn't take an nonce) but forcing pre-AEAD cipher suites in the AEAD
interface is less painful than forcing AEADs into the EVP_CIPHER
interface. Over time, more and more cipher suites will be exposed as
TLS-specific AEADs and then ssl/ can drop support for EVP_CIPHER.
See original code from upstream:

Apart from the obvious little issues, this also works around a
(seeming) libtool/linker:
a.c defines a symbol:
int kFoo;
b.c uses it:
extern int kFoo;
int f() {
return kFoo;
}
compile them:
$ gcc -c a.c
$ gcc -c b.c
and create a dummy main in order to run it, main.c:
int f();
int main() {
return f();
}
this works as expected:
$ gcc main.c a.o b.o
but, if we make an archive:
$ ar q lib.a a.o b.o
and use that:
$ gcc main.c lib.a
Undefined symbols for architecture x86_64
"_kFoo", referenced from:
_f in lib.a(b.o)
(It doesn't matter what order the .o files are put into the .a)
Linux and Windows don't seem to have this problem.
nm on a.o shows that the symbol is of type "C", which is a "common symbol"[1].
Basically the linker will merge multiple common symbol definitions together.
If ones makes a.c read:
int kFoo = 0;
Then one gets a type "D" symbol - a "data section symbol" and everything works
just fine.
This might actually be a libtool bug instead of an ld bug: Looking at `xxd
lib.a | less`, the __.SYMDEF SORTED index at the beginning of the archive
doesn't contain an entry for kFoo unless initialised.
