ENH: Implement linking with paths to library files instead of -L and -l separation. See bug #3832

  - This is purely an implementation improvement.  No interface has changed.
  - Create cmComputeLinkInformation class
  - Move and re-implement logic from:
      cmLocalGenerator::ComputeLinkInformation
      cmOrderLinkDirectories
  - Link libraries to targets with their full path (if it is known)
  - Dirs specified with link_directories command still added with -L
  - Make link type specific to library names without paths
    (name libfoo.a without path becomes -Wl,-Bstatic -lfoo)
  - Make directory ordering specific to a runtime path computation feature
    (look for conflicting SONAMEs instead of library names)
  - Implement proper rpath support on HP-UX and AIX.

+Notes about linking on various platforms:
+
+------------------------------------------------------------------------------
+
+Linux, FreeBSD, Mac OS X, IRIX, Sun, Windows:
+
+Linking to libraries using the full path works fine.
+
+------------------------------------------------------------------------------
+
+On AIX, more work is needed.
+
+  The "-bnoipath" option is needed.  From "man ld":
+
+    Note: If you specify a shared object, or an archive file
+    containing a shared object, with an absolute or relative path
+    name, instead of with the -lName flag, the path name is
+    included in the import file ID string in the loader section of
+    the output file. You can override this behavior with the
+    -bnoipath option.
+
+      noipath
+
+        For shared objects listed on the command-line, rather than
+        specified with the -l flag, use a null path component when
+        listing the shared object in the loader section of the
+        output file. A null path component is always used for
+        shared objects specified with the -l flag. This option
+        does not affect the specification of a path component by
+        using a line beginning with #! in an import file. The
+        default is the ipath option.
+
+  This prevents the full path specified on the compile line from being
+  compiled directly into the binary.
+
+  By default the linker places -L paths in the embedded runtime path.
+  In order to implement CMake's RPATH interface correctly, we need the
+  -blibpath:Path option.  From "man ld":
+
+      libpath:Path
+
+        Uses Path as the library path when writing the loader section
+        of the output file. Path is neither checked for validity nor
+        used when searching for libraries specified by the -l flag.
+        Path overrides any library paths generated when the -L flag is
+        used.
+
+        If you do not specify any -L flags, or if you specify the
+        nolibpath option, the default library path information is
+        written in the loader section of the output file. The default
+        library path information is the value of the LIBPATH
+        environment variable if it is defined, and /usr/lib:/lib,
+        otherwise.
+
+  We can pass -Wl,-blibpath:/usr/lib:/lib always to avoid the -L stuff
+  and not break when the user sets LIBPATH.  Then if we want to add an
+  rpath we insert it into the option before /usr/lib.
+
+------------------------------------------------------------------------------
+
+On HP-UX, more work is needed.  There are differences between
+versions.
+
+ld: 92453-07 linker linker ld B.10.33 990520
+
+  Linking with a full path works okay for static and shared libraries.
+  The linker seems to always put the full path to where the library
+  was found in the binary whether using a full path or -lfoo syntax.
+  Transitive link dependencies work just fine due to the full paths.
+
+  It has the "-l:libfoo.sl" option.  The +nodefaultrpath is accepted
+  but not documented and does not seem to do anything.  There is no
+  +forceload option.
+
+ld: 92453-07 linker ld HP Itanium(R) B.12.41  IPF/IPF
+
+  Linking with a full path works okay for static libraries.
+
+  Linking with a full path works okay for shared libraries.  However
+  dependent (transitive) libraries of those linked directly must be
+  either found with an rpath stored in the direct dependencies or
+  found in -L paths as if they were specified with "-l:libfoo.sl"
+  (really "-l:<soname>").  The search matches that of the dynamic
+  loader but only with -L paths.  In other words, if we have an
+  executable that links to shared library bar which links to shared
+  library foo, the link line for the exe must contain
+
+    /dir/with/bar/libbar.sl -L/dir/with/foo
+
+  It does not matter whether the exe wants to link to foo directly or
+  whether /dir/with/foo/libfoo.sl is listed.  The -L path must still
+  be present.  It should match the runtime path computed for the
+  executable taking all directly and transitively linked libraries
+  into account.
+
+  The "+nodefaultrpath" option should be used to avoid getting -L
+  paths in the rpath unless we add our own rpath with +b.  This means
+  that skip-build-rpath should use this option.
+
+  See documentation in "man ld", "man dld.so", and
+  http://docs.hp.com/en/B2355-90968/creatingandusinglibraries.htm
+
+    +[no]defaultrpath
+      +defaultrpath is the default.  Include any paths that are
+      specified with -L in the embedded path, unless you specify the
+      +b option.  If you use +b, only the path list specified by +b is
+      in the embedded path.
+
+      The +nodefaultrpath option removes all library paths that were
+      specified with the -L option from the embedded path.  The linker
+      searches the library paths specified by the -L option at link
+      time.  At run time, the only library paths searched are those
+      specified by the environment variables LD_LIBRARY_PATH and
+      SHLIB_PATH, library paths specified by the +b linker option, and
+      finally the default library paths.
+
+    +rpathfirst
+      This option will cause the paths specified in RPATH (embedded
+      path) to be used before the paths specified in LD_LIBRARY_PATH
+      or SHLIB_PATH, in searching for shared libraries.  This changes
+      the default search order of LD_LIBRARY_PATH, SHLIB_PATH, and
+      RPATH (embedded path).

-/** \class cmOrderLinkDirectories
- * \brief Compute the best -L path order
- *
- * This class computes the best order for -L paths.
- * It tries to make sure full path specified libraries are 
- * used.  For example if you have /usr/mylib/libfoo.a on as
- * a link library for a target, and you also have /usr/lib/libbar.a
- * and you also have /usr/lib/libfoo.a, then you would
- * want -L/usr/mylib -L/usr/lib to make sure the correct libfoo.a is 
- * found by the linker.  The algorithm is as follows:
- * - foreach library create a vector of directories it exists in.
- * - foreach directory create a vector of directories that must come
- *   after it, put this in a map<dir, vector<dir>> mapping from a directory
- *   to the vector of directories that it must be before.
- * - put all directories into a vector
- * - sort the vector with a compare function CanBeBefore
- *   CanBeBefore returns true if a directory is OK to be before
- *   another directory.  This is determined by looking at the 
- *   map<dir vector<dir>> and seeing if d1 is in the vector for d2.
