Following on from the earlier safestack work we provide the basis for
fixing the lhash code such that unused static inline functions do not
cause linker errors for applications including those headers.
This brings the lhash code into line with the safestack code.

The safestack code generation was generating a little too much. Some of
it could be done with a normal macro.

We fix 3 problems with safestack:
- Including an openssl header file without linking against libcrypto
can cause compilation failures (even if the app does not otherwise need
to link against libcrypto). See issue #8102
- Recent changes means that applications in no-deprecated builds will need
to include additional macro calls in the source code for all stacks that
they need to use - which is an API break. This changes avoids that
necessity.
- It is not possible to write code using stacks that works in both a
no-deprecated and a normal build of OpenSSL. See issue #12707.
Fixes#12707
Contains a partial fix for #8102. A similar PR will be needed for hash to
fully fix.
