during "make errors" and thus during "make update".

Fix lots of bugs that util/ck_errf.pl can detect automatically.
Various others of these are still left to fix; that's why
"make update" will complain loudly when run now.

functions and macros.

This change has associated tags: LEVITTE_before_const and
LEVITTE_after_const.  Those will be removed when this change has been
properly reviewed.

I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get

functions need to be constified, and therefore meant a number of easy

Now, if someone could explain to me why OBJ_dup() cheats...

Fixes to d2i_ASN1_OBJECT, ASN1_INTEGER_to_BN and a_strex.c

ASN1_TIME fixes.

New function c2i_ASN1_OBJECT().

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.

Also fix a memory leak in PKCS#7 routines.
