During Configure we attempt to check the kernel version of this platform
to see whether we can compile the AFALG engine. If the kernel version
looks recent enough then we enable AFALG. However when we compile
e_afalg.c we check the version of the linux headers. If there is a
mismatch between the linux headers and the currently running kernel then
we don't compile the AFLAG engine and continue. This was causing a link
error.

There is a preference for suffixes to indicate that a function is internal
rather than prefixes. Note: the suffix is only required to disambiguate
internal functions and public symbols with the same name (but different
case)

The no-deprecated build was failing because afalg was relying on a

The reason to do so is that some of the generators detect PIC flags
like -fPIC and -KPIC, and those are normally delivered in LD_CFLAGS.

The AFALG engine created a global EVP_CIPHER instance but was not freeing

Before the 'Introduce the "pic" / "no-pic" config option' commit, the
shared_cflag value for the chosen config would be part of the make
variable CFLAG, which got replicated into CFLAGS and ASFLAGS.
Since said commit, the shared_cflag value has become a make variable
of its own, SHARED_CFLAG (which is left empty in a "no-pic" build).
However, ASFLAGS was forgotten. That's what's corrected with this
change.

Implementation experience has shown that the original plan for async wait
fds was too simplistic. Originally the async logic created a pipe internally
and user/engine code could then get access to it via API calls. It is more
flexible if the engine is able to create its own fd and provide it to the
async code.
Another issue is that there can be a lot of churn in the fd value within
the context of (say) a single SSL connection leading to continually adding
and removing fds from (say) epoll. It is better if we can provide some
stability of the fd value across a whole SSL connection. This is
problematic because an engine has no concept of an SSL connection.
This commit refactors things to introduce an ASYNC_WAIT_CTX which acts as a
proxy for an SSL connection down at the engine layer.

Until now, the engines in engines/ were only built as dynamicaly
loadable ones if shared libraries were built.
We not dissociate the two and can build dynamicaly loadable engines
even if we only build static libcrypto and libssl. This is controlled
with the option (enable|disable|no)-static-engine, defaulting to
no-static-engine.
Note that the engines in crypto/engine/ (dynamic and cryptodev) will
always be built into libcrypto.

This takes us away from the idea that we know exactly how our static
libraries are going to get used. Instead, we make them available to
build shareable things with, be it other shared libraries or DSOs.
On the other hand, we also have greater control of when the shared
library cflags. They will never be used with object files meant got
binaries, such as apps/openssl or test/test*.
With unified, we take this a bit further and prepare for having to
deal with extra cflags specifically to be used with DSOs (dynamic
engines), libraries and binaries (applications).

The engine DSOs were named as if they were shared libraries, and could
end up having all sorts of fancy names:
Cygwin: cygFOO.dll
Mingw: FOOeay32.dll
Unix: libFOO.so / libFOO.sl / libFOO.dylib / ...
This may be confusing, since they look like libraries one should link
with at link time, when they're just DSOs.
It's therefore time to rename them, and do it consistently on all
platforms:
Cygwin & Mingw: FOO.dll
Unix: FOO.{so,sl,dylib,...}
Interestingly enough, the MSVC and VMS builds always did it this way.

Originally, the Makefile.shared targets described what they used as
input for a shared object, be it a shared library or a DSO. It turned
out, however, that the link_o targets were used exclusively for
engines and the link_a targets were for libcrypto and libssl.
This rename fest turns and indication on the kind of input the targets

All those flags existed because we had all the dependencies versioned
in the repository, and wanted to have it be consistent, no matter what
the local configuration was. Now that the dependencies are gone from
the versioned Makefile.ins, it makes much more sense to use the exact
same flags as when compiling the object files.
