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:
Avoid finding nasm.

Log message:
set OVERRIDE_DIRDEPTH because there are config.{guess,sub} files
deep within the hierarchy (not used by the build),
from Rumko per mail to pkgsrc-users

Log message:
Add define of new type to mpeg4ip.h replacement.
Bump revision, since depending packages failed to compile.

Log message:
update to 1.6.1; this is the last release because the author changed
jobs; the release contains final fixes and cleanup
(The original distfile is corrupt, and the author appearently not able
to fix it, so we fetch a repackaged version from FreeBSD.)

Log message:
The package supports installation to DESTDIR.

Log message:
include <stdint.h> explicitely to get uint16_t (on NetBSD/sys/types.h
defines these, but on Linux it does not)
should fix build problem reported by Lieven De Keyzer in pkgsrc-users

Proxy-commit for drochner@:
The bootstrap script checks too much and isn't useful -- just don't use it.
