Allow asan, msan and ubsan to be configured with shared libraries

The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
or similar platform dependent variables, just in case the shared
libraries were built with -rpath.  Unfortunately, this doesn't work
too well with asan, msan or ubsan.

So, the solution is to forbid the combination of shared libraries,
-rpath and any of the sanity analyzers we can configure.

This changes util/shlib_wrap.sh so it only contains the code that sets
LD_PRELOAD when -rpath has been used when configuring.

Avoid EVP_PKEY_cmp() crash on EC keys without public component

Some hardware devices don't provide the public EC_POINT data. The only
way for X509_check_private_key() to validate that the key matches a
given certificate is to actually perform a sign operation and then
verify it using the public key in the certificate.

Maybe that can come later, as discussed in issue 1532. But for now let's
at least make it fail gracefully and not crash.

Remove some dead code from rec_layer_s3.c

It is never valid to call ssl3_read_bytes with
type == SSL3_RT_CHANGE_CIPHER_SPEC, and in fact we check for valid values
for type near the beginning of the function. Therefore this check will never
be true and can be removed.

Fix math in BN_bn2dec comment.

The bound on log(2)/3 on the second line is incorrect and has an extra
zero compared to the divisions in the third line. log(2)/3 = 0.10034...

of three.

The actual code appears to be fine. Just the comments are wrong.
