Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Bump all packages that use perl, or depend on a p5-* package, or
are called p5-*.

I hope that's all of them.

Log message:
Set BUILDLINK_ABI_DEPENDS correctly (with +=, not ?=)
It turns out there were a lot of these.

Log message:
setusercontext() is in -lutil for DragonFly, FreeBSD and NetBSD.
avoid to include own alternative one in libskey,
or it cause some troubles on programs using setusercontext() and skey,
and setusercontext() is only required for bundled skeyaudit(1).

Bump PKGREVISION.

Log message:
Fixes PR#44324.

* On DragonFly, rmd160.h exists and required functions are defined there,
  but not in any library, so ignore it.
* On DragonFly and FreeBSD, MD5 and MD4 functions are in libmd.

Log message:
defined(%hash) is deprecated.

Log message:
Remove @dirrm entries from PLISTs

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:
Also need to take care of md5 for Solaris, PR 40434.

Log message:
Solaris's md4.h and sha1.h are not good enough for this package,
and MD5_* is in libmd5.
Fixes build failure reported by PR 40434.
