This was done by the following
        find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
        print unless $. == 1 && m@/\* .*\.[ch] \*/@;
        close ARGV if eof; # Close file to reset $.

And then some hand-editing of other files.

There are header files in crypto/ that are used by a number of crypto/

affected source code and Makefiles.

The header files that got moved are:

2b8dc08b74 Call of memcmp with null pointers in obj_cmp()
The function obj_cmp() (file crypto/objects/obj_dat.c) can in some
situations call memcmp() with a null pointer and a zero length.

This is invalid behaviour. When compiling openssl with undefined
behaviour sanitizer (add -fsanitize=undefined to compile flags) this
can be seen. One example that triggers this behaviour is the pkcs7
command (but there are others, e.g. I've seen it with the timestamp
function):
apps/openssl pkcs7 -in test/testp7.pem

What happens is that obj_cmp takes objects of the type ASN1_OBJECT and
passes their ->data pointer to memcmp. Zero-sized ASN1_OBJECT
structures can have a null pointer as data.

56d88027f0 Fix the heap corruption in libeay32!OBJ_add_object.
Original 'sizeof(ADDED_OBJ)' was replaced with 'sizeof(*ao)'. However,
they return different sizes. Therefore as the result heap gets corrupted
and at some point later debug version of malloc() detects the corruption.

On x86 we can observe that as follows:

sizeof(*ao) == 4
sizeof(*ao[0]) == sizeof(ADDED_OBJ) == 8

Issue reproduces with either enabling CRT debug heap or Application
Verifier's full-page heap.

Basic debugging data from the moment the corruption is first detected:

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.

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.
