remove Version-Requirements from core!

It has been replaced by CPAN::Meta::Requirements, which is just the
same code, renamed.

It was renamed (and now removed) to avoid conflicts on case-sensitive
filesystems between version::Internals and Version::Requirements.

-=head1 NAME
-
-Version::Requirements - a set of version requirements for a CPAN dist
-
-=head1 VERSION
-
-version 0.101022
-
-=head1 SYNOPSIS
-
-  use Version::Requirements;
-
-  my $build_requires = Version::Requirements->new;
-
-  $build_requires->add_minimum('Library::Foo' => 1.208);
-
-  $build_requires->add_minimum('Library::Foo' => 2.602);
-
-  $build_requires->add_minimum('Module::Bar'  => 'v1.2.3');
-
-  $METAyml->{build_requires} = $build_requires->as_string_hash;
-
-=head1 DESCRIPTION
-
-A Version::Requirements object models a set of version constraints like those
-specified in the F<META.yml> or F<META.json> files in CPAN distributions.  It
-can be built up by adding more and more constraints, and it will reduce them to
-the simplest representation.
-
-Logically impossible constraints will be identified immediately by thrown
-exceptions.
-
-=head1 METHODS
-
-=head2 new
-
-  my $req = Version::Requirements->new;
-
-This returns a new Version::Requirements object.  It ignores any arguments
-given.
-
-=head2 add_minimum
-
-  $req->add_minimum( $module => $version );
-
-This adds a new minimum version requirement.  If the new requirement is
-redundant to the existing specification, this has no effect.
-
-Minimum requirements are inclusive.  C<$version> is required, along with any
-greater version number.
-
-This method returns the requirements object.
-
-=head2 add_maximum
-
-  $req->add_maximum( $module => $version );
-
-This adds a new maximum version requirement.  If the new requirement is
-redundant to the existing specification, this has no effect.
-
-Maximum requirements are inclusive.  No version strictly greater than the given
-version is allowed.
-
-This method returns the requirements object.
-
-=head2 add_exclusion
-
-  $req->add_exclusion( $module => $version );
-
-This adds a new excluded version.  For example, you might use these three
-method calls:
-
-  $req->add_minimum( $module => '1.00' );
-  $req->add_maximum( $module => '1.82' );
-
-  $req->add_exclusion( $module => '1.75' );
-
-Any version between 1.00 and 1.82 inclusive would be acceptable, except for
-1.75.
-
-This method returns the requirements object.
-
-=head2 exact_version
-
-  $req->exact_version( $module => $version );
-
-This sets the version required for the given module to I<exactly> the given
-version.  No other version would be considered acceptable.
-
-This method returns the requirements object.
-
-=head2 add_requirements
-
-  $req->add_requirements( $another_req_object );
-
-This method adds all the requirements in the given Version::Requirements object
-to the requirements object on which it was called.  If there are any conflicts,
-an exception is thrown.
-
-This method returns the requirements object.
-
-=head2 accepts_module
-
-  my $bool = $req->accepts_modules($module => $version);
-
-Given an module and version, this method returns true if the version
-specification for the module accepts the provided version.  In other words,
-given:
-
-  Module => '>= 1.00, < 2.00'
-
-We will accept 1.00 and 1.75 but not 0.50 or 2.00.
-
-For modules that do not appear in the requirements, this method will return
-true.
-
-=head2 clear_requirement
-
-  $req->clear_requirement( $module );
-
-This removes the requirement for a given module from the object.
-
-This method returns the requirements object.
-
-=head2 required_modules
-
-This method returns a list of all the modules for which requirements have been
-specified.
-
-=head2 clone
-
-  $req->clone;
-
-This method returns a clone of the invocant.  The clone and the original object
-can then be changed independent of one another.
-
-=head2 is_simple
-
-This method returns true if and only if all requirements are inclusive minimums
--- that is, if their string expression is just the version number.
-
-=head2 is_finalized
-
-This method returns true if the requirements have been finalized by having the
-C<finalize> method called on them.
-
-=head2 finalize
-
-This method marks the requirements finalized.  Subsequent attempts to change
-the requirements will be fatal, I<if> they would result in a change.  If they
-would not alter the requirements, they have no effect.
-
-If a finalized set of requirements is cloned, the cloned requirements are not
-also finalized.
-
-=head2 as_string_hash
-
-This returns a reference to a hash describing the requirements using the
-strings in the F<META.yml> specification.
-
-For example after the following program:
-
-  my $req = Version::Requirements->new;
-
-  $req->add_minimum('Version::Requirements' => 0.102);
-
-  $req->add_minimum('Library::Foo' => 1.208);
-
-  $req->add_maximum('Library::Foo' => 2.602);
-
-  $req->add_minimum('Module::Bar'  => 'v1.2.3');
-
-  $req->add_exclusion('Module::Bar'  => 'v1.2.8');
-
-  $req->exact_version('Xyzzy'  => '6.01');
-
-  my $hashref = $req->as_string_hash;
-
-C<$hashref> would contain:
-
-  {
-    'Version::Requirements' => '0.102',
-    'Library::Foo' => '>= 1.208, <= 2.206',
-    'Module::Bar'  => '>= v1.2.3, != v1.2.8',
-    'Xyzzy'        => '== 6.01',
-  }
-
-=head2 from_string_hash
-
-  my $req = Version::Requirements->from_string_hash( \%hash );
-
-This is an alternate constructor for a Version::Requirements object.  It takes
-a hash of module names and version requirement strings and returns a new
-Version::Requirements object.
