      Make a number of changes to the OS/2 build. Submitter's comment below. · 9d68b289

      Submitter's comment:
      
      This patch:
      
      a) Introduces a new file os2/backwardify.pl.
      
      b) Introduces a new mk1mf.pl variable $preamble.  As you can see, it may
         be used also to move some OS-specific code to VC-CE too (the the
         first chunk of the patch);
      
      c) The DESCRIPTION specifier of the .def file is made more informative:
         now it contains the version number too.  On OS/2 it is made conformant
         to OS/2 conventions; in particular, when one runs the standard command
      	BLDLEVEL this.DLL
         one can see:
      
         Vendor:      www.openssl.org/
         Revision:    0.9.7c
         Description: OpenSSL: implementation of Secure Socket Layer; DLL for library crypto.  Build for EMX -Zmtd
      
         [I did not make Win32 descriptions as informative as this - I'm afraid to
          break something.  Be welcome to fix this.]
      
      d) On OS/2 the generated DLL was hardly usable (it had a shared initialized
         data segment).
      
      e) On OS/2 the generated DLLs had names like ssl.dll.  However, DLL names on
         OS/2 are "global data".  It is hard to have several DLLs with the same
         name on the system.  Thus this precluded coexistence of OpenSSL with DLLs
         for other SLL implementations - or other name clashes.  I transparently
         changed the names of the DLLs to open_ssl.dll and cryptssl.dll.
      
      f) The file added in (a) is used to create "forwarder" DLLs, so the
         applications expecting the "old" DLL names may use the new DLLs
         transparently.  (A presence of these DLLs on the system nullifies (e),
         but makes old applications work.  This is a stopgap measure until the
         old applications are relinked.  Systems with no old applications do not
         need these DLLs, so may enjoy all the benefits of (e).)
      
         The new DLLs are placed in os2/ and os2/noname subdirectories.
      
      g) The makefiles created with os2/OS2-EMX.cmd did not work (some mysterious
         meaningless failures).  The change to util/pl/OS2-EMX.pl uses the
         variable introduced in (b) to switch the Makefiles to SHELL=sh syntax.
         All these backslashes are removed, and the generated Makefiles started to
         work.
      
      h) Running os2/OS2-EMX.cmd now prints out what to do next.

      If dynamically-loadable ENGINEs are linked against a shared-library version · 04dc4edb
      Richard Levitte authored
      of libcrypto, then it is possible that when they are loaded they will share
      the same static data as the loading application/library. This means it will
      be too late to set memory/ERR/ex_data/[etc] callbacks, but entirely
      unnecessary to try.
      
      This change (and a great part of this comment) was implemented in
      0.9.8-dev a long time ago, but slightly differently.  In 0.9.8-dev, a
      specific function that just returns a pointer to some static object is
      used. For 0.9.7x, we couldn't do that, since the way we handle feature
      freezes is, among other, to not add any more non-static functions.
      Instead, we use the function ERR_get_implementation() and compare the
      returned value with fns->err_fns, a member of fns that already is
      there, and which therefore can safely be used in this manner.
      
      What happens is that if the loaded ENGINE's return value from this
      function matches the loading application/library's return value - they
      share static data. If they don't match, the loaded ENGINE has its own
      copy of libcrypto's static data and so the callbacks need to be set.
