Since COMP_METHOD is now defined in comp_lcl.h, it is no longer possible to create new TLS compression methods without using the OpenSSL source. Only ZLIB is supported by default. Also, since the types are opaque, #ifdef guards to use "char *" instead of the real type aren't necessary. The changes are actually minor. Adding missing copyright to some files makes the diff misleadingly big. Reviewed-by: Matt Caswell <matt@openssl.org>
