- Change how the ASN1_API decorator is used in libtasn1.h, for GTK-DOC.
- Changed license of libtasn1.pc from GPLv3+ to LGPLv2.1+.

Log message:
Update to 2.1:

Version 2.1 (released 2009-04-17)
- Fix compilation failure on platforms that can't generate empty archives,
  e.g., Mac OS X.  Reported by David Reiser <dbreiser@gmail.com>.

Version 2.0 (released 2009-04-13)
- Optimized tree generation.
- ASN1 parser code re-generated using Bison 2.4.1.
- Build with more warning flags.  Many compiler warnings fixed.
- Compiled with -fvisibility=hidden by default if supported.
  See http://gcc.gnu.org/wiki/Visibility
- The libtasn1-config tool has been removed.
  For application developers, please stop using libtasn1-config for
  finding libtasn1, use proper autoconf checks or pkg-config instead.
  For users that need a libtasn1 that provides a libtasn1-config
  script (for use with older applications), use libtasn1 v1.x instead.
  Version 1.x is still supported.

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:
Fix build under Mac OS X:
The GNU library ends up being empty and "ar" complains if you try to create
an archive. Simply skip the directory during the build to avoid this.
