Only treat an ASN1_ANY type as an integer if it has the V_ASN1_INTEGER
tag: V_ASN1_NEG_INTEGER is an internal only value which is never used
for on the wire encoding.

Building with -DCHARSET_EBCDIC and using --strict-warnings resulted in
lots of miscellaneous errors. This fixes it.

If the ASN.1 BIO is presented with a large length field read it in
chunks of increasing size checking for EOF on each read. This prevents
small files allocating excessive amounts of data.

The Unix build was the last to retain the classic build scheme. The
new unified scheme has matured enough, even though some details may
need polishing.

This does NOT cover any .pl file that has other copyright in it.

The check_defer() function was used to ensure that EVP_cleanup() was always
called before OBJ_cleanup(). The new cleanup code ensures this so it is
no longer needed.
Remove obj_cleanup() call in OID config module: it is not needed
any more either.

There is a preference for suffixes to indicate that a function is internal
rather than prefixes. Note: the suffix is only required to disambiguate
internal functions and public symbols with the same name (but different
case)

Move the the BIO_METHOD and BIO structures into internal header files,
provide appropriate accessor methods and update all internal code to use

This takes us away from the idea that we know exactly how our static
libraries are going to get used. Instead, we make them available to
build shareable things with, be it other shared libraries or DSOs.
On the other hand, we also have greater control of when the shared
library cflags. They will never be used with object files meant got
binaries, such as apps/openssl or test/test*.
With unified, we take this a bit further and prepare for having to
deal with extra cflags specifically to be used with DSOs (dynamic
engines), libraries and binaries (applications).

All those flags existed because we had all the dependencies versioned
in the repository, and wanted to have it be consistent, no matter what
the local configuration was. Now that the dependencies are gone from
the versioned Makefile.ins, it makes much more sense to use the exact
same flags as when compiling the object files.
