e34c66c6b0 RT3754: check for NULL pointer
Fix both the caller to error out on malloc failure, as well as the
eventual callee to handle a NULL gracefully.

b39fc56061 Identify and move common internal libcrypto header files
There are header files in crypto/ that are used by a number of crypto/
submodules.  Move those to crypto/include/internal and adapt the
affected source code and Makefiles.

The header files that got moved are:

crypto/cryptolib.h
crypto/md32_common.h

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.

7b36590b17 What was I smoking? EVP_PKEY_cmp() should return with 0 if
EVP_PKEY_cmp_parameters() returned 0, otherwise it should
go on processing the public key component.  Thia has nothing
to do with the proper handling of EC parameters or not.

cf1b7d9664 Make all configuration macros available for application by making
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

26a3a48d65 There have been a number of complaints from a number of sources that names
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.
