- eliminate ambiguities between GNU-ish and SysV-ish make flavors;
- switch [back] to -e;
- fold/unify rules;

This is follow-up to the patch introducing common BUILDENV. Idea is
to collect as much parameters in $(TOP) as possible and "strip" lower
Makefiles for most variables [and thus makes them more readable].

1107.  He says:

This is a followup to the NetWare patch that was applied to beta3.  It
does the following:

- Fixes a problem in the CLib build with undefined symbols.

- Adds the ability to use BSD sockets as the default for the OpenSSL
  socket BIO.  NetWare supports 2 flavors of sockets and our Apache
  developers need BSD sockets as a configurable option when building
  OpenSSL.  This adds that for them.

- Updates to the INSTALL.NW file to explain new options.

I have tried very hard to make sure all the changes are in NetWare
specific files or guarded carefully to make sure they only impact
NetWare builds.  I have tested the Windows build to make sure it does
not break that since we have made changes to mk1mf.pl.

We are still working the gcc cross compile for NetWare issue and hope
to have a patch for that before beta 6 is released.

and I really can't be bothered...

make no-sha512 more effective on platforms, which don't support 64-bit
integer type of *any* kind.

[most importantly] put back dependencies accidentaly eliminated in
check-in #13342.

- hide the EC_KEY structure definition in ec_lcl.c + add
  some functions to use/access the EC_KEY fields
- change the way how method specific data (ecdsa/ecdh) is
  attached to a EC_KEY
- add ECDSA_sign_ex and ECDSA_do_sign_ex functions with
  additional parameters for pre-computed values
- rebuild libeay.num from 0.9.7

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.

Another missing module in the VMS build files.I believe this is
the last, though...

1. "unsigned long long" isn't portable changed: to BN_ULLONG.
2. The LL prefix isn't allowed in VC++ but it isn't needed where it is used.
2. Avoid lots of compiler warnings about signed/unsigned mismatches.
3. Include new library directory pqueue in mk1mf build system.
4. Update symbols.

Fix Win32 build system to use 'Makefile' instead of 'Makefile.ssl'.
