cf3404fcc7 Change the return type of EVP_EncodeUpdate
Previously EVP_EncodeUpdate returned a void. However there are a couple
of error conditions that can occur. Therefore the return type has been
changed to an int, with 0 indicating error and 1 indicating success.

b01e1644d7 Fix: PEM_read_bio_PrivateKey with no-ui / no-stdio
If openssl is compiled with no-ui or no-stdio, then PEM_read_bio_PrivateKey fails if a password but no callback is provided.

The reason is that the premature return in the PEM_def_callback implementation when OPENSSL_NO_STDIO or OPENSSL_NO_UI is defined, comes too early.

This patch moves the ifdef block to the correct place.

d78df5dfd6 Reject inappropriate private key encryption ciphers.
The traditional private key encryption algorithm doesn't function
properly if the IV length of the cipher is zero. These ciphers
(e.g. ECB mode) are not suitable for private key encryption
anyway.

3c27208fab Remove #error from include files.
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.

4c9b0a0314 Initialize potentially uninitialized local variables
Compiling OpenSSL code with MSVC and /W4 results in a number of warnings.
One category of warnings is particularly interesting - C4701 (potentially
uninitialized local variable 'name' used). This warning pretty much means
that there's a code path which results in uninitialized variables being used
or returned. Depending on compiler, its options, OS, values in registers
and/or stack, the results can be nondeterministic. Cases like this are very
hard to debug so it's rational to fix these issues.

This patch contains a set of trivial fixes for all the C4701 warnings (just
initializing variables to 0 or NULL or appropriate error code) to make sure
that deterministic values will be returned from all the execution paths.

RT#3835

Signed-off-by: Matt Caswell <matt@openssl.org>

Matt's note: All of these appear to be bogus warnings, i.e. there isn't
actually a code path where an unitialised variable could be used - its just
that the compiler hasn't been able to figure that out from the logic. So
this commit is just about silencing spurious warnings.
