VMS: stop trying to build shared libraries from static ones

The possibility to do this was killed when we started producing object
file names with encoded intention (and possibly different builds), and
leads to build errors.

With that, 'libobj2shlib' is renamed to 'obj2shlib' to reflect this
design change. The old name is still used if the new one isn't
available, for the sake of backward compatibility.

Configuration: Simplify generating list of generated files in build file templates

Computing the value of the GENERATED variable in the build file
templates is somewhat overcomplicated, and because of possible
duplication errors, changes are potentially error prone.

Looking more closely at how this list is determined, it can be
observed that the exact list of files to check is consistently
available in all the values found in the %unified_info tables
'depends', 'sources' and 'shared_sources', and all that's needed is to
filter those values so only those present as keys in the 'generate'
table are left.

This computation is also common for all build files, so due to its
apparent complexity, we move it to common0.tmpl, with the result left
in a global variable (@generated), to be consumed by all build file
templates.

common0.tmpl is included among the files to process when creating
build files, but unlike common.tmpl, it comes first of all.

Streamline dependency generation

It seems that only gcc -MMD produces dependency files that are "sane"
for our needs. For all other methods, some post processing is needed:

- 'makedepend' (Unix) insists that object files are located in the
same spot as the source file.
- 'cl /Zs /showIncludes' (Visual C) has "Note: including file: " where
we'd like to see the object.
- 'CC/DECC' (VMS) insists that the object file is located in the
current directory, i.e. it strips away all directory information.

So far, we've managed this (except for the VMS case) with individual
uncommented perl command lines directly in the build file template.
We're now collecting these diverse hacks into one perl script that
takes an argument to tell what kind of input to expect and that
massages whatever it gets on STDIN and outputs the result on STDOUT.

Make "make variables" config attributes for overridable flags

With the support of "make variables" comes the possibility for the
user to override them. However, we need to make a difference between
defaults that we use (and that should be overridable by the user) and
flags that are crucial for building OpenSSL (should not be
overridable).

Typically, overridable flags are those setting optimization levels,
warnings levels, that kind of thing, while non-overridable flags are,
for example, macros that indicate aspects of how the config target
should be treated, such as L_ENDIAN and B_ENDIAN.

We do that differentiation by allowing upper case attributes in the
config targets, named exactly like the "make variables" we support,
and reserving the lower case attributes for non-overridable project
flags.

Harmonize the make variables across all known platforms families

The make variables LIB_CFLAGS, DSO_CFLAGS and so on were used in
addition to CFLAGS and so on. This works without problem on Unix and
Windows, where options with different purposes (such as -D and -I) can
appear anywhere on the command line and get accumulated as they come.
This is not necessarely so on VMS. For example, macros must all be
collected and given through one /DEFINE, and the same goes for
inclusion directories (/INCLUDE).

So, to harmonize all platforms, we repurpose make variables starting
with LIB_, DSO_ and BIN_ to be all encompassing variables that
collects the corresponding values from CFLAGS, CPPFLAGS, DEFINES,
INCLUDES and so on together with possible config target values
specific for libraries DSOs and programs, and use them instead of the
general ones everywhere.

This will, for example, allow VMS to use the exact same generators for
generated files that go through cpp as all other platforms, something
that has been impossible to do safely before now.
