b4faea50c3 Use safer sizeof variant in malloc 
For a local variable:
        TYPE *p;
Allocations like this are "risky":
        p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption.  Instead do this:
        p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.

efa7dd6444 free NULL cleanup 11 
Don't check for NULL before calling free functions. This gets:

        A sk_free use within OBJ_sigid_free
        TS_TST_INFO_free (rest of TS_ API was okay)
        Doc update for UI_free (all uses were fine)

4d428cd250 Dead code removal: #if 0 bio, comp, rand 
The start of removing dead code.
A remaining #if 0 in bss_conn.c needs more thought.

1b31b5ad56 Modify compression code so it avoids using ex_data free functions. This 
stops applications that call CRYPTO_free_all_ex_data() prematurely leaking
memory.

5b0f1f7d13 Because libraries on Windows lack useful version information, the zlib 
guys had to change the name to differentiate with older versions when
a backward incompatibility came up.  Of course, we need to adapt.
This change simply tries to load the library through the newer name
(ZLIB1) first, and if that fails, it tries the good old ZLIB.

This compiles and runs on Linux, and external applications have no
