In some cases, one might want to generate some source files from
others, that's done as follows:

    GENERATE[foo.s]=asm/something.pl $(CFLAGS)
    GENERATE[bar.s]=asm/bar.S

The value of each GENERATE line is a command line or part of it.
Configure places no rules on the command line, except the the first
item muct be the generator file.  It is, however, entirely up to the
build file template to define exactly how those command lines should
be handled, how the output is captured and so on.

Move RSA struct in the job local struct.
The change is applied also to other crypto operations (e.g. DSA) to
make things consistent.
Reviewed-by: NRichard Levitte <levitte@openssl.org>
Reviewed-by: NMatt Caswell <matt@openssl.org>

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

Example:
  openssl speed -engine dasync -elapsed -async_jobs 32 rsa2048

 - Prefer TLS v1.2 ciphers to legacy ciphers.

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...

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.
