Remove a hack from ssl_test_old

ssl_test_old was reaching inside the SSL structure and changing the internal
BIO values. This is completely unneccessary, and was causing an abort in the
test when enabling TLSv1.3.

I also removed the need for ssl_test_old to include ssl_locl.h. This
required the addition of some missing accessors for SSL_COMP name and id
fields.

Only build the body of e_padlock when there are lower level routines

engines/e_padlock.c assumes that for all x86 and x86_64 platforms, the
lower level routines will be present.  However, that's not always
true, for example for solaris-x86-cc, and that leads to build errors.

The better solution is to have configure detect if the lower level

they are, and use that macro in our C code.

Stop init loops

Under certain circumstances, the libcrypto init code would loop,
causing a deadlock.  This would typically happen if something in
ossl_init_base() caused an OpenSSL error, and the error stack routines
would recurse into the init code before the flag that ossl_init_base()
had been run was checked.

This change makes sure ossl_init_base isn't run once more of the base
is initiated.

Thanks to Dmitry Kostjuchenko for the idea.

Revert "Fixed deadlock in CRYPTO_THREAD_run_once for Windows"

This reverts commit edc18749bd5dfb7e12513d3978f78f9b56104fd6.

The proposed fix is incorrect. It marks the "run_once" code as having
finished before it has. The intended semantics of run_once is that no
threads should proceed until the code has run exactly once. With this
change the "second" thread will think the run_once code has already been
run and will continue, even though it is still in progress. This could
result in a crash or other incorrect behaviour.
