Remove the obsolete misleading comment and code related to it.
The comment "The following should not return 1, otherwise, things
are very strange" is from the very first commit of OpenSSL. The
really meaning of the comment is if the identical session can be
found from internal cache after calling get_session_cb but not
found before calling get_session_cb, it is just strange.
The value 1 was originated from the old doc of SSLeay, reversed
from the actual return value of SSL_CTX_add_session().
Anyway either return value of SSL_CTX_add_session() should not
interrupt the session resumption process. So the checking of
return value of SSL_CTX_add_session() is not necessary.

Simplify Makefile.shared
Makefile.shared was designed to figure out static library names,
shared library names, library version compatibility, import library
names and the like on its own. This was a design for pre-1.1.0
OpenSSL because the main Makefile didn't have all that knowledge.
With 1.1.0, the situation isn't the same, a lot more knowledge is
included in the main Makefile, and while Makefile.shared did things
right most of the time (there are some corner cases, such as the
choice of .sl or .so as DSO extension on some HPUX versions), there's
still an inherent fragility when one has to keep an eye on
Makefile.shared to make sure it produces what the main Makefile
produces.
This change simplifies Makefile.shared by removing all its
"intelligence" and have it depend entirely on the input from the main
Makefile instead. That way, all the naming is driven from
configuration data.

Fix undefined behaviour in e_aes_cbc_hmac_sha256.c and e_aes_cbc_hmac_sha1.c
In TLS mode of operation the padding value "pad" is obtained along with the
maximum possible padding value "maxpad". If pad > maxpad then the data is
invalid. However we must continue anyway because this is constant time code.
We calculate the payload length like this:
inp_len = len - (SHA_DIGEST_LENGTH + pad + 1);
However if pad is invalid then inp_len ends up -ve (actually large +ve
because it is a size_t).
Later we do this:
/* verify HMAC */
out += inp_len;
len -= inp_len;
This ends up with "out" pointing before the buffer which is undefined
behaviour. Next we calculate "p" like this:
unsigned char *p =
out + len - 1 - maxpad - SHA256_DIGEST_LENGTH;
Because of the "out + len" term the -ve inp_len value is cancelled out
so "p" points to valid memory (although technically the pointer arithmetic
is undefined behaviour again).
We only ever then dereference "p" and never "out" directly so there is
never an invalid read based on the bad pointer - so there is no security
issue.
This commit fixes the undefined behaviour by ensuring we use maxpad in
place of pad, if the supplied pad is invalid.
