If init failed we'd like to set an error code to indicate that. But if
init failed then when the error system tries to load its strings its going
to fail again. We could get into an infinite loop. Therefore we just set
a single error the first time around. After that no error is set.

The new init functions can fail if the library has already been stopped. We
should be able to indicate failure with a 0 return value.

The local variable tmp was declared static when it shouldn't be. This
is in the no-threads implementation, and it was immediately initialised
to something else on every invokation of the function so it doesn't break
anything...but still shouldn't be there.

Added all missing X509 error codes to the verify(1) manpage, but

The old building scripts get removed, they are hopelessly gone in bit
rot by now.

Also remove the old symbol hacks.  They were needed needed to shorten
some names to 31 characters, and to resolve other symbol clashes.
Because we now compile with /NAMES=(AS_IS,SHORTENED), this is no
longer required.

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:

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.

Under certain conditions, one might not want to output certain
sections of a template file.  This adds the functions output_off() and
output_on(), reachable inside the templates.  And example usage in a
Makefile template could be this:

	@ : {- output_off() if $config{no_shared}; "" -}
	... lines dealing with shared libraries
	@ : {- output_on() -}

The logic to figure out the combinations of --prefix and --openssldir
has stayed in Configure so far, with Unix paths as defaults.

However, since we're making Configure increasingly platform agnostic,
these defaults need to change and adapt to the platform, along with
the logic to combine them.

The easiest to provide for this is to move the logic and the defaults
away from Configure and into the build files.

This also means that the definition of the macros ENGINESDIR and
OPENSSLDIR move away from include/openssl/opensslconf.h and into the
build files.

Makefile.in is adapted accordingly.

With some compilers, C macros are defined differently on the command
line than on Unix.  It could be that the flad to define them isn't -D,
it could also be that they need to be grouped together and not be mixed
in with the other compiler flags (that's how it's done on VMS, for
example).

On Unix family platform configurations, we can continue to have macro
definitions mixed in with the rest of the flags, so the changes in
Configurations/*.conf are kept to an absolute minimum.

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.
Reviewed-by: NRich Salz <rsalz@openssl.org>

There were cases where some input was absolute, and concatenating it
to the diretory to the source or build top could fail spectacularly.
Let's check the input first to see if it's absolute.

And while we're on the subject of checking if a file or dir spec is
absolute using file_name_is_absolute() has its own quirks on VMS,
where a logical name is considered absolute under most circumstances.
This is perfectly correct from a VMS point of view, but when parsing
the build.info files, we want single word file or directory names to
only be checked syntactically.  A function isabsolute() that does the
right thing is the solution.
