Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:
While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.
To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:
#include "internal/file.h" # located in 'include/internal'
#include "internal/file_int.h" # located in 'crypto/include/internal'
This commit moves the private crypto headers from
'crypto/include/internal' to 'include/crypto'
As a result, the include directives become unambiguous
#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'
hence the superfluous '_int.h' suffixes can be stripped.
The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

$(SHLIB_MAJOR).$(SHLIB_MINOR) is really a synonym for
$(SHLIB_VERSION_NUMBER), and is therefore an added complexity,
so better to use $(SHLIB_VERSION_NUMBER) directly. SHLIB_MAJOR and
SHLIB_MINOR are now unused, but are kept around purely as information
in case someone relies on their existence.
At the same time, add support for custom shared library extensions
with the three new Makefile variables SHLIB_EXT, SHLIB_EXT_SIMPLE and
SHLIB_EXT_IMPORT. By default, they hold the variants of shared
library extensions we support. On mingw and cygwin, SHLIB_EXT_IMPORT
is defined; on all other Unix platforms, it's empty.
An example to get shared libraries with a slightly different SOVER name:
$ make SHLIB_EXT='.$(SHLIB_VERSION_NUMBER).so'

Now that INCLUDE considers both the source and build trees, no need

So far, MingW shared libraries were named like this
libeay32.dll + libeay32.dll.a
ssleay32.dll + ssleay32.dll.a
That naming scheme is antiquated, a reminicense of SSLeay. We're
therefore changing the scheme to something that's more like the rest
of OpenSSL.
There are two factors to remember:
- Windows libraries have no recorded SOvers, which means that the
shared library version must be encoded in the name. According to
some, it's unwise to encode extra periods in a Windows file name,
so we convert version number periods to underscores.
- MingW has multilib ability. However, DLLs need to reside with the
binaries that use them, so to allow both 32-bit and 64-bit DLLs to
reside in the same place, we add '-x64' in the name of the 64-bit
ones.
The resulting name scheme (for SOver 1.1) is this:
on x86:
libcrypto-1_1.dll + libcrypto.dll.a
libssl-1_1.dll + libssl.dll.a
on x86_64:
libcrypto-1_1-x64.dll + libcrypto.dll.a
libssl-1_1-x64.dll + libssl.dll.a
An observation is that the import lib is the same for both
architectures. Not to worry, though, as they will be installed in
PREFIX/lib/ for x86 and PREFIX/lib64/ for x86_64.
As a side effect, MingW got its own targets in Makefile.shared.
link_dso.mingw-shared and link_app.mingw-shared are aliases for the
corresponding cygwin-shared targets. link_shlib.mingw-shared is,
however, a target separated from the cygwin one.

As part of this, change util/mkdef.pl to stop adding libraries to
depend on in its output. mkdef.pl should ONLY output a symbol
vector.
Because symbol names can't be longer than 31 characters, we use the
compiler to shorten those that are longer down to 23 characters plus
an 8 character CRC. To make sure users of our header files will pick
up on that automatically, add the DEC C supported extra headers files
__decc_include_prologue.h and __decc_include_epilogue.h.
Furthermore, we add a config.com, so VMS people can configure just as
comfortably as any Unix folks, thusly:
@config

Cygwin and Mingw name their libraries a bit differently from the rest
of the POSIXly universe, we need to adapt to that.
In Makefile.tmpl, it means that some hunks will only be output
conditionally.
This also means that shared_extension for the Cygwin and Mingw
configurations in Configurations/10-main.conf are changing from .dll.a
to .dll. Makefile.shared does a fine job without having them
specified, and it's much easier to work with tucking an extra .a at
the end of files in the installation recipes than any amount of name
rewrites, especially with the support of the SHARED_NAME in the top
build.info.

In build.info files, make the include directory in the build directory
absolute, or Configure will think it should be added to the source
directory top. Configure will turn it into a relative path if
possible.

Now that we have the foundation for the "unified" build scheme in
place, we add build.info files. They have been generated from the
Makefiles in the same directories. Things that are platform specific
will appear in later commits.
