d88736df4d Windows, VMS: build fixes
The naming of generated assembler wasn't done quite right.  There are
assembler files that are generated from a perl script, and there are
those who are not.  Only the former must be renamed to the platform
specific asm extension.

Furthermore, we need to make sure that 'OSSL_provider_init' isn't case
sensitive on VMS, to allow for the least surprise for provider
builders.

1842f369e5 ENGINE modules aren't special, so call them MODULES
The only thing that makes an ENGINE module special is its entry
points.  Other than that, it's a normal dynamically loadable module,
nothing special about it.  This change has us stop pretending anything
else.

We retain using ENGINE as a term for installation, because it's
related to a specific installation directory, and we therefore also
mark ENGINE modules specifically as such with an attribute in the
build.info files.

994e86a9ff Build: use attributes to indicate installed script classes
We have two classes of scripts to be installed, those that are
installed as "normal" programs, and those that are installed as "misc"
scripts.  These classes are installed in different locations, so the
build file templates must pay attention.

Because we didn't have the tools to indicate what scripts go where, we
had these scripts hard coded in the build template files, with the
maintenance issues that may cause.  Now that we have attributes, those
can be used to classify the installed scripts, and have the build file
templates simply check the attributes to know what's what.

Furthermore, the 'tsget.pl' script exists both as 'tsget.pl' and
'tsget', which is done by installing a symbolic link (or copy).  This
link name is now given through an attribute, which results in even
less hard coding in the Unix Makefile template.

3a63dbef15 Switch to MAJOR.MINOR.PATCH versioning and version 3.0.0-dev
We're strictly use version numbers of the form MAJOR.MINOR.PATCH.
Letter releases are things of days past.

The most central change is that we now express the version number with
three macros, one for each part of the version number:

    OPENSSL_VERSION_MAJOR
    OPENSSL_VERSION_MINOR
    OPENSSL_VERSION_PATCH

We also provide two additional macros to express pre-release and build
metadata information (also specified in semantic versioning):

    OPENSSL_VERSION_PRE_RELEASE
    OPENSSL_VERSION_BUILD_METADATA

To get the library's idea of all those values, we introduce the
following functions:

    unsigned int OPENSSL_version_major(void);
    unsigned int OPENSSL_version_minor(void);
    unsigned int OPENSSL_version_patch(void);
    const char *OPENSSL_version_pre_release(void);
    const char *OPENSSL_version_build_metadata(void);

Additionally, for shared library versioning (which is out of scope in
semantic versioning, but that we still need):

    OPENSSL_SHLIB_VERSION

We also provide a macro that contains the release date.  This is not
part of the version number, but is extra information that we want to
be able to display:

    OPENSSL_RELEASE_DATE

Finally, also provide the following convenience functions:

    const char *OPENSSL_version_text(void);
    const char *OPENSSL_version_text_full(void);

The following macros and functions are deprecated, and while currently
existing for backward compatibility, they are expected to disappear:

    OPENSSL_VERSION_NUMBER
    OPENSSL_VERSION_TEXT
    OPENSSL_VERSION
    OpenSSL_version_num()
    OpenSSL_version()

Also, this function is introduced to replace OpenSSL_version() for all
indexes except for OPENSSL_VERSION:

    OPENSSL_info()

For configuration, the option 'newversion-only' is added to disable all
the macros and functions that are mentioned as deprecated above.

c1123d9f7e Allow parallel install
When trying 'make -j{n} install', you may occasionally run into
trouble because to sub-targets (install_dev and install_runtime) try
to install the same shared libraries.  That makes parallel install
difficult.

This is solved by dividing install_runtime into two parts, one for
libraries and one for programs, and have install_dev depend on
install_runtime_libs instead of installing the shared runtime
libraries itself.

ecc347f5f5 Windows build: build foo.d after foo.obj
We made the build of foo.obj depend on foo.d, meaning the latter gets
built first.  Unfortunately, the way the compiler works, we are forced
to redirect all output to foo.d, meaning that if the source contains
an error, the build fails without showing those errors.

We therefore remove the dependency and force the build of foo.d to
always happen after build of foo.obj.

b3023ced6b Windows: Produce a static version of the public libraries, always
When building shared libraries on Windows, we had a clash between
'libcrypto.lib' the static routine library and 'libcrypto.lib' the
import library.

We now change it so the static versions of our libraries get '_static'
appended to their names.  These will never get installed, but can
still be used for our internal purposes, such as internal tests.

When building non-shared, the renaming mechanism doesn't come into
play.  In that case, the static libraries 'libcrypto.lib' and
'libssl.lib' are installed, just as always.

We only had targets for the "simple" shared library names (libfoo.so
and not libfoo.so.x.y on Unix, import library libfoo.lib but not
libfoo.dll on Windows).  This has created some confusion why it wasn't
possible to rebuild the less "simple" name directly (just as an
example, someone who mistook the import library on Windows for a
static library, removed the DLL and then found it was difficult to
rebuild directly), so we change the target to include all possible
names.

ef2dfc9902 Refactor linker script generation
The generation of linker scripts was badly balanced, as all sorts of
platform dependent stuff went into the top build.info, when that part
should really be made as simply and generic as possible.

Therefore, we move a lot of the "magic" to the build files templates,
since they are the place for platform dependent things.  What remains
is to parametrize just enough in the build.info file to generate the
linker scripts correctly for each associated library.

"linker script" is a term usually reserved for certain Unix linkers.
However, we only use them to say what symbols should be exported, so
we use the term loosely for all platforms.  The internal extension is
'.ld', and is changed by the build file templates as appropriate for
each target platform.

Note that this adds extra meaning to the value of the shared_target
attribute.

8258975c94 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.

BASE_windows.

Along with this, change the quotation of macro definitions and include

bbb9413b7e 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.

element denoting VC install-path "flavour", i.e. where to install things.
Instead of looking at 3rd, let's look at last. This allows to override
flavour from template in a simple way.

Configurations/10-main.conf: define generic "flavour" in VC-common
template. Since VC-W32 was the only recognized "flavour", remove
"flavour" definitions from all targets/templates, but VC-WIN32. And
rename VC-W32 to VC-WOW.

abe256e795 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.
