Initial commit of a new wrapper script framework that encapsulates
the non-buildlink-related code and moves it out of mk/buildlink3 into
mk/wrapper.  The buildlink3 code is modified to simply hook its
transformations into the wrapper script framework.

The wrapper script framework has some new features:

* Support automatically passing "ABI" flags to the compiler and linker
  depending on the value of ${ABI}.  Currently supports the SunPro
  compiler with ${ABI} == 64 and the MIPSPro compiler with ${ABI} as
  any of 32, n32, o32, and 64.

* making UnixWare GCC accept -rpath options and silently converting
  them into an appropriate LD_RUN_PATH

* Add cmd-sink-interix-gcc and cmd-sink-interix-ld that errors out
  when it sees -fpic/-fPIC and -shared/-Bshareable, respectively
  (requested by <tv>).

* Much improved debugging output.  It's possible to output the wrapper
  work log in-line with normal output by setting WRAPPER_LOG to
  "stderr".

Important differences in behaviour from the old buildlink3 code include:

* Only move the -l options to the end of the command line, leaving the
  -L options in-place.

* Extend the autodetection of the libtool mode to detect "compile" and
  "uninstall".

* Fix problem noted in both PR pkg/24760 and PR pkg/25500, where
  -L/usr/lib/* was being mangled improperly.

* Remove the top-level "buildlink" target; instead, make buildlinking
  occur as part of the "wrapper" target.

* mangle and sub-mangle are only meant to transform directories in
  -I, -L, and rpath options, so remove the lines in
  buildlink3/gen-transform.sh that transformed bare directories.

* Add the ability for the libtool wrapper to be called just to unwrap
  an existing libtool archive by running:

	libtool --mode=unwrap -o libfoo.la

  The old --fix-la syntax no longer works.


20040818
========
* Initial release of a new wrapper script framework that encapsulates
  the non-buildlink-related code and moves it out of mk/buildlink3.
  These features include:

   * making MIPSpro accept GCC options
   * making MIPSpro "ucode" accept GCC options
   * making SunPro accept GCC options
   * making "ld" accept -Wl,* options and silently removing the "-Wl,"
   * (NEW) making UnixWare GCC accept -rpath options and silently
     converting them into an appropriate LD_RUN_PATH

  One major benefit of this is that the buildlink3 code is now much
  tighter and easier to understand since it concerns itself solely
  with buildlink-related details.  I haven't yet optimized the wrapper
  cache, so the new wrapper scripts may take slightly longer to execute
  than the old buildlink3 wrapper scripts, but I'll be improving this
  over time.


20040821
========
* Move the inclusion of $cmd_sink outside of the main loop in wrapper.sh
  so that the $cmd_sink script can be used to globally scan and process
  the arguments.  Move the LD_RUN_PATH code to a cmd-sink-unixware-gcc
  script.  Garbage-collect the now unused export_vars-related code.

* Add cmd-sink-aix-xlc for AIX xlc that munges -Wl,-R* into an
  appropriate -blibpath option.

* Add cmd-sink-interix-gcc and cmd-sink-interix-ld that errors out
  when it sees -fpic/-fPIC and -shared/-Bshareable, respectively
  (requested by <tv>).

* Move the code that converts full paths to shared libraries into the
  "-Ldir -llib" equivalents from the buildlink3 code into wrapper/logic.
  Remove the same from bsd.buildlink3.mk and gen-transform.sh.

* Move the code that checks for absolute rpaths from the buildlink3
  code into wrapper/arg-source.  Remove the same from bsd.buildlink3.mk
  and gen-transform.sh.

* Only move the -l options to the end of the command line, leaving the
  -L options in-place.

* Add more debugging code.


20040824
========
* Fix quoting problems after arguments are transformed.  Remove the
  hack that was inserted that magically made almost everything work
  because we do it the right way now.

* Move the inclusion of $logic outside of the main loop in wrapper.sh
  so that the $logic script doesn't have to worry about underflowing
  the argument buffer.

* Encapsulate the loop in wrapper.sh that fills the argument buffer
  entirely within the arg-source script.

* Move from the logic script into the arg-source script the
  transformations that merge or split arguments.

* Fix bug where skipargs was effectively being ignored if it was more
  than 1.

* Handle the whitespace in transformations in the logic script that
  turn one library option into multiple library options, e.g.
  "-lreadline" -> "-ledit -ltermcap".

* Allow you to specify an environment variable WRAPPER_SKIP_TRANSFORM
  for whether you wish to skip the transformation step in the logic
  script.  This is intended for testing purposes.

* Added check_prog() and init_lib() functions to the shell code library
  to make it more reusable outside of the wrapper framework.

* Allow the msg_log() function to output to "stdout" or "stderr".  If
  you want to have all of the logging appear on the screen, then you
  can now set WRAPPER_LOG=stderr.

* Make some of the script components not overridable on a per-wrapper
  basis.

* Add a gen-transform.sh script that generates transformation sedfiles.
  The "transform" script is used to transform arguments, while the
  "untransform" script is used to unwrap files.  Move the no-rpath
  logic from buildlink3/gen-transform.sh into wrapper/gen-transform.sh
  since it's not buildlink3-specific.

* Check for a non-empty blibpath before adding the option in
  cmd-sink-aix-xlc.

* Extend the autodetection of the libtool mode to detect "compile" and
  "uninstall".

* Add a cmd-sink-libtool script that doesn't pass linker options to
  libtool unless we're in "link" mode.

* Set _USE_RPATH to "yes" for UnixWare so that the wrappers will see the
  rpath options and convert them to a LD_RUN_PATH definition.

* Add more debugging code.


20040826
========
* Rewrite buildlink3/gen-transform.sh to produce more precise sed commands.
  Drop some unused commands from the mini-language, and add a few more
  that are more restrictive in their scope.

* Fix problem where repeated options weren't properly handled by some
  of sed commands.  It's not enough that they're "global replace",
  since some patterns match separator characters before and after each
  option.  We must repeat those patterns twice to catch all instances
  correctly.

* Fix problem noted in both PR pkg/24760 and PR pkg/25500, where
  -L/usr/lib/* was being mangled improperly.

* Remove the top-level "buildlink" target; instead, make buildlinking
  occur as part of the "wrapper" target.

* Add more debugging code.


20040828
========
* Added a head_queue function to shell-lib that returns the head of the
  named queue without popping it off the front of the queue.

* Strip consecutive, repeated library options from the command line when
  we read it in the logic script.

* Be more careful about not underflowing the argument buffer.


20040906
========
* shell-lib was moved into pkgsrc/mk/scripts; correct references to that
  file in the wrapper code.

* Use opt-sub instead of sub-mangle when protecting -I/usr/include/*
  and -L/usr/lib/* from buildlink transformations.  This avoids adding
  lines that look like "-I-I..." in the transformation sedfiles.

* mangle and sub-mangle are only meant to transform directories in
  -I, -L, and rpath options, so remove the lines in
  buildlink3/gen-transform.sh that transformed bare directories.

* Fix bug in strip-slashdot where the "." wasn't backquoted and thus
  matched all characters instead of only the "." character.

* Change the libtool wrapper to use a modified buildcmd script that
  doesn't rearrange any of the arguments.  This should fix spurious
  problems where libtool doesn't understand how to parse the command
  line when the -l options are moved to the end of the argument list.

* Fix bug in the logic script where the $cachearg and $cachedarg
  weren't being properly set at all times, which caused the cache to
  contain the wrong transformed argument.


20040907
========
* Support automatically passing "ABI" flags to the compiler and linker
  depending on the value of ${ABI}.  Currently supports the SunPro
  compiler with ${ABI} == 64 and the MIPSPro compiler with ${ABI} as
  any of 32, n32, o32, and 64.

* Move back the code that splits absolute paths to shared libraries
  from arg-source back into logic.  This allows us to correctly skip
  splitting those paths based on the previous option.  Also add a
  sanity check that the library name in the split argument doesn't
  contain a "/" since shell globs are not as precise as REs.

* Don't transform the path given after --dynamic-linker (used by GNU
  ld for ELF linkage).

* Add the ability for the libtool wrapper to be called just to unwrap
  an existing libtool archive by running:

	libtool --mode=unwrap -o libfoo.la


20040914
========
* Add a loop in libtool-fix-la to ensure that all of the options listed
  in the dependency_libs lines of *.lai files are processed.  This fixes
  a buildlink3 leakage bug.

* Merge the gen-transform.sh scripts between buildlink3 and wrapper and
  place them all in wrapper.  This makes sense since the commands simply
  allow for many types of transformations, which buildlink3 takes
  advantage of, but there is nothing inherently buildlink-ish about
  those commands.

* Don't directly manipulate SUBST_SED.unwrap.  Instead, create the
  value of SUBST_SED.unwrap by combining several other variables
  (currently just _UNWRAP_SED) to ensure that the correct ordering is
  preserved.

* Correct some confusing debugging messages.
