Remove socks5 due to distfile unavailability and a license which forbids
redistribution. Equivalent functionality is provided by the free net/dante
package (or even "ssh -D" for simple use cases)

Log message:
Remove pkgviews: don't set PKG_INSTALLATION_TYPES in Makefiles.

Remove example rc.d scripts from PLISTs.

These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.

Log message:
Rename struct to not conflict with C99's restrict keyword.

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

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.
