Add support for async jobs in OpenSSL speed
Summary of the changes:
* Move the calls to the crypto operations inside wrapper functions.
This is required because ASYNC_start_job takes a function as an argument.
* Add new function run_benchmark() that manages the jobs for all the operations.
In the POSIX case it uses a select() to receive the events from the engine
and resume the jobs that are paused, while in the WIN case it uses PeekNamedPipe()
* Add new option argument async_jobs to enable and specify the number of async jobs

Rework the default cipherlist.
- Always prefer forward-secure handshakes.
- Consistently order ECDSA above RSA.
- Next, always prefer AEADs to non-AEADs, irrespective of strength.
- Within AEADs, prefer GCM > CHACHA > CCM for a given strength.
- Prefer TLS v1.2 ciphers to legacy ciphers.
- Remove rarely used DSS, IDEA, SEED, CAMELLIA, CCM from the default
list to reduce ClientHello bloat.

bn/asm/x86[_64]-mont*.pl: complement alloca with page-walking.
Some OSes, *cough*-dows, insist on stack being "wired" to
physical memory in strictly sequential manner, i.e. if stack
allocation spans two pages, then reference to farmost one can
be punishable by SEGV. But page walking can do good even on
other OSes, because it guarantees that villain thread hits
the guard page before it can make damage to innocent one...

Rework based on feedback:
1. Cleaned up eventfd handling
2. Reworked socket setup code to allow other algorithms to be added in
future
3. Fixed compile errors for static build
4. Added error to error stack in all cases of ALG_PERR/ALG_ERR
5. Called afalg_aes_128_cbc() from bind() to avoid race conditions
6. Used MAX_INFLIGHT define in io_getevents system call
7. Coding style fixes

perhaps it has _some_ value; but we shouldn't let the two compete.

No -fno-common for Darwin
When object files with common block symbols are added to static
libraries on Darwin, those symbols are invisible to the linker that
tries to use them. Our solution was to use -fno-common when compiling
C source.
Unfortunately, there is assembler code that defines OPENSSL_ia32cap_P
as a common block symbol, unconditionally, and in some cases, there is
no other definition. -fno-common doesn't help in this case.
However, 'ranlib -c' adds common block symbols to the index of the
static library, which makes them visible to the linker using it, and
that solves the problem we've seen.
The common conclusion is, either use -fno-common or ranlib -c on
Darwin. Since we have common block symbols unconditionally, choosing
the method for our source is easy.
Add support for application supplied any defined by callback. An
application can change the selector value if it wishes. This is
mainly intended for values which are only known at runtime, for
example dynamically created OIDs.

Restore the zlib / zlib-dynamic logic
The proper logic is that both zlib and zlib-dynamic are disabled by
default and that enabling zlib-dynamic would enable zlib. Somewhere
along the way, the logic got changed, zlib-dynamic was enabled by
default and zlib didn't get automatically enabled.
PVK files with abnormally large length or salt fields can cause an
integer overflow which can result in an OOB read and heap corruption.
However this is an rarely used format and private key files do not
normally come from untrusted sources the security implications not
significant.
Fix by limiting PVK length field to 100K and salt to 10K: these should be
more than enough to cover any files encountered in practice.

Clean up curve25519 build
- Remove OPENSSL_X25519_X86_64 which never worked, because we don't have
the assembly.
- Also remove OPENSSL_SMALL (which should have been
OPENSSL_SMALL_FOOTPRINT) which isn't a priority at the moment.
2) Make broken SNI parsing explicit. SNI was intended to be extensible
to new name types but RFC 4366 defined the syntax inextensibly, and
OpenSSL has never parsed SNI in a way that would allow adding a new name
type. RFC 6066 fixed the definition but due to broken implementations
being widespread, it appears impossible to ever extend SNI.
3) Annotate resumption behaviour. OpenSSL doesn't currently handle all
extensions correctly upon resumption. Annotate for further clean-up.
Handle KDF in ECDH_compute_key instead of requiring each implementation
support it. This modifies the compute_key method: now it allocates and
populates a buffer containing the shared secret.

Don't copy from %target to %config so much, see %config as a complement
We copied $target{cflags}, $target{defines} and a few more to %config,

There are a few cases where we still fiddle with %target, but that's

Configure - Get rid of the special thread_cflag, replace with thread_scheme
The thread_cflag setting filled a double role, as kinda sorta an
indicator of thread scheme, and as cflags. Some configs also added
lflags and ex_libs for multithreading regardless of if threading would
be enabled or not.
Instead of this, add threading cflags among in the cflag setting,
threading lflags in the lflag setting and so on if and only if threads
are enabled (which they are by default).
Also, for configs where there are no special cflags for threading (the
VMS configs are of that kind), this makes it possible to still clearly
mention what thread scheme is used.
The exact value of thread scheme is currently ignored except when it's
"(unknown)", and thereby only serves as a flag to tell if we know how
to build for multi-threading in a particular config. Yet, the
currently used values are "(unknown)", "pthreads", "uithreads" (a.k.a
solaris threads) and "winthreads".

Configure - get rid of the special debug_ and release_ settings
Instead, make the build type ("debug" or "release") available through
$config{build_type} and let the configs themselves figure out what the
usual settings (such as "cflags", "lflags" and so on) should be
accordingly.
The benefit with this is that we can now have debug and release
variants of any setting, not just those Configure supports, and may
also involve other factors (the MSVC flags /MD[d] and /MT[d] involve
both build type and whether threading is enabled or not)

it to the BASE_unix config template and add corresponding ones in the
other BASE_* config templates. The Windows one is probably incomplete,

anyway.
This required making the %withargs table global, so perl snippets in
the configs can use it.
