Changes 1.43.0:
New Libraries:
* Functional/factory: Function objects for dynamic and by-value construction.
* Functional/forward: Function object adapters to address the forwarding
 problem.
Major Updates:
* Range: Boost.Range has undergone extensive updates that it include all of the
  features from the recently reviewed Boost.RangeEx.
* Range-based version of the full STL iterator based algorithms.
* Range adaptors which can be combined with range-based algorithms for
  unpresedented expressiveness and efficiency.
* New functions: irange, istream_range, join, combine.
Updated Libraries
Build System:
* When cross-compiling to GNU targets, static libraries are properly created.
  Previously, using such libraries resulted in Archive has no index error.
* The naming of DLL and import libraries with gcc compiler on Windows, both
  mingw and cygwin, now matches default conventions of those environments.
  Previously, the naming scheme was the same as for other Windows compilers.
Updated Tools:
* Quickbook: Unicode escape characters.
* Support the UTF-8 byte order mark.
* Disallow [ in simple markup. Fixes some errors with mismatched punctuation.
* Add a command line flag (-D) to define macros at the command line.
* Improved post-processor output.
* Check that [section] and [endsect] tags are balanced in templates.

Allow python26. From Jan Danielsson.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Decorate .endif with the name of the variable the .if tested.
