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.

Update to 1.2.8

Unfortunately details changes don't seem to be available:

After a long hiatus, new releases of libspf2! Development work from a number
of contributors has resulted in the release of versions up to 1.2.8. It is
recommended that all users upgrade as soon as possible, since this release
fixes some significant bugs. This release also comes with new doxygen
documentation which should make the code easier to understand and
cross-reference.

Log message:
libspf2 implements the Sender Policy Framework, a part of the SPF/SRS
protocol pair. libspf2 is a library which allows email systems such as
Sendmail, Postfix, Exim, Zmailer and MS Exchange to check SPF records
and make sure that the email is authorized by the domain name that it
is coming from. This prevents email forgery, commonly used by spammers,
scammers and email viruses/worms.
