Don't have #error statements in header files, but instead wrap
the contents of that file in #ifndef OPENSSL_NO_xxx
This means it is now always safe to include the header file.

mkdef.pl was not detecting no-comp functions. This updates the header file
so that mkdef.pl detects that no-comp applies, and the functions are marked
accordingly.

Pass entire CTLOG_STORE to SCT_print, rather than just the SCT's CTLOG

SCT_print now looks up the correct CT log for you.

Remove 'log' field from SCT and related accessors

In order to still have access to an SCT's CTLOG when calling SCT_print,
SSL_CTX_get0_ctlog_store has been added.

Improved documentation for some CT functions in openssl/ssl.h.

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.

There is now no longer a need to set locking callbacks!!
