- Make use of the functions given through CRYPTO_set_mem_functions().
- CRYPTO_free(), CRYPTO_clear_free() and CRYPTO_secure_free() now receive
  __FILE__ and __LINE__.
- The API for CRYPTO_set_mem_functions() and CRYPTO_get_mem_functions()
  is slightly changed, the implementation for free() now takes a couple
  of extra arguments, taking __FILE__ and __LINE__.
- The CRYPTO_ memory functions will *always* receive __FILE__ and __LINE__
  from the corresponding OPENSSL_ macros, regardless of if crypto-mdebug
  has been enabled or not.  The reason is that if someone swaps out the
  malloc(), realloc() and free() implementations, we can't know if they
  will use them or not.

Macro definitions "should" be found in $config{defines}, but some
configs haven't transfered macro definitions from their 'cflags'
settings (which isn't mandatory anyway), so check both places.

This check is meaningless on VMS and only produce an error because the
underlying shell (DCL) doesn't understand sh syntax such as '2>&1'.

Depending on user preferences, Configure might get something like
--PREFIX=blah just as well as --prefix=blah, or "SHARED" just as well
as "shared".  On VMS, let's therefore lowercase at least the portion
of the argument before a possible equal sign.

For good measure, we lowercase the arguments to be checked in
config.com as well.  The original argument is sent on to Configure,
however.

A long time ago, Solaris cc didn't seem to handle -Wl, linker options,
while gcc on Solaris required it.  Since then, Solaris cc has
developed to understand -Wl, options, and our little dance to figure
out how to pass linker options to the C compiler that's used isn't
needed any more.

mk1mf was wondering about the options no-heartbeats and
no-crypto-mdebug-backtrace, so we add option hooks them.  They only
need to become OPENSSL_NO_ macros in opensslconf.h, so nothing
additional needs to be done.

Also, add "-DOPENSSL_PIC" when shared libraries are produced.

Three header files from crypto/include/internal were used by
util/mkdef.pl.  This should never be needed.  Some test program used
these, which made it a valid reason at the time to make the some
internal symbols public in the shared libraries, but that's not the
case any more.

However, to be able to link libssl.so, some symbols found in
include/internal headers still need to be made public.

On some platforms, the implementation is such that a signed char
triggers a warning when used with is*() functions.  On others, the
behavior is outright buggy when presented with a char that happens
to get promoted to a negative integer.

The safest thing is to cast the char that's used to an unsigned char.

To force it on anyone using --strict-warnings was the wrong move, as
this is an option best left to those who know what they're doing.

DllMain is a symbol that needs to be global, but no one needs to know.
However, some compilers will warn if there isn't a declaration before
the function is defined.  Just add a declaration before the function

Most of the times, it seems that socklen_t is unsigned.
Unfortunately, this isn't always the case, and it doesn't compare with
a size_t without warning.

A cast resolves the issue.

While IO::Socket::IP is a core perl module (since Perl v5.19.8, or so
says corelist), IO::Socket::INET6 has been around longer, is said to
be more widely deployed, and most importantly, seems to have less bugs
hitting us.  We therefore prefer IO::Socket::INET6, and only fall back
to IO::Socket::IP if the former doesn't exist on the local system.
