Subject: [PATCH] configure.ac: properly quote macro arguments
Autoconf 2.70+ is more picky about the quotation (even though with
previous versions the arguments should have been quoted, too). When we
don't quote macros inside the AC_CACHE_VAL macro - some of the Autoconf
initialization is wrongly ordered in ./configure script and we keep
seeing bugs like:
./configure: line 2165: ac_fn_c_try_run: command not found

Subject: [PATCH] Gracefully handle failed initializations
In OpenSSL 3.0 these algorithms have been moved to the legacy provider
which is not enabled by default. This means allocation can and do fail.
Handle failed allocations by returning an actual error instead of
crashing later with a NULL context.
