[Boost-build] Boost Jam 3.1.15

This release sees a variety of fixes for long standing Perforce/Jam 
problems. Most of them relating to running actions in parallel with the 
-jN option. The end result of the changes is that running parallel 
actions is now reliably possible in Unix and Windows environments. Many 
thanks to Noel for joining the effort, to implement and fix the Unix 
side of stuff.

* Add support for building bjam with pgi and pathscale toolsets. -- Noel B.
* Implement running action commands through pipes (-p option) to fix 
jumbled output when using parallel execution with -j option. This is 
implemented for Unix variants, and Windows (Win32/NT). -- Rene R., Noel B.
* Add "sun" as alias to Sun Workshop compiler tools. -- Rene R.
* Set MAXLINE in jam.h to 23k bytes for AIX. The piecemeal archive 
action was broken with the default MAXLINE of 102400. Because the AIX 
shell uses some of the 24k default buffer size for its own use, I 
reduced it to 23k. -- Noel B.
* Make use of output dir options of msvc to not polute src dir with 
compiled files. -- Rene R.
* A small fix, so -d+2 will always show the "real" commands being 
executed instead of casually the name of a temporary batch file. -- 
Roland S.
* Add test to check 'bjam -n'. -- Rene R.
* Add test to check 'bjam -d2'. -- Rene R.
* Bring back missing output of -n option. The -o option continues to be 
broken as it has been for a long time now because of the @ file feature. 
-- Rene R.
* Update GC support to work with Boehm GC 7.0. -- Rene R.
* Revert the BOOST_BUILD_PATH change, since the directory passed to 
boost-build should be first in searched paths, else project local build 
system will not be picked correctly. The order had been changed to allow 
searching of alternate user-config.jam files from boost build. This 
better should be done with --user-config= switch or similar. -- Roland S.
* Initial support for defining action body from Python. -- Vladimir P.
* Implement @() expansion during parse phase. -- Rene R.
* Define OSPLAT var unconditionally, and more generically, when 
possible. -- Rene R.
* Fix undeclared INT_MAX on some platforms, i.e. Linux. -- Rene R.
* Modified execunix.c to add support for terminating processes that 
consume too much cpu or that hang and fail to consume cpu at all. This 
in support of the bjam -lx option. -- Noel B.
* Add internal dependencies for multi-file generating actions to 
indicate that the targets all only appear when the first target appears. 
This fixes the long standing problem Perforce/Jam has with multi-file 
actions and parallel execution (-jN). -- Rene R.
* Add test of -l limit option now that it's implemented on windows and 
unix. -- Rene R.
* Add test for no-op @() expansion. -- Rene R.
* Handle invalid formats of @() as doing a straight substitution instead 
of erroring out. -- Rene R.
* Various fixes to compile on SGI/Irix. -- Noel B.
* Add output for when actions timeout with -lN option. -- Rene R., Noel B.
* Add needed include (according to XOPEN) for definition of WIFEXITED 
and WEXITSTATUS. -- Markus S.

Enjoy.
