Remove the old threading API

All OpenSSL code has now been transferred to use the new threading API,
so the old one is no longer used and can be removed. We provide some compat
macros for removed functions which are all no-ops.

Make sure the effect of "pic" / "no-pic" is used with assembler compilations

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
