Log:
[new_feature] directory locking targets
Two directory locking targets (do-lock, do-unlock) are implemented in
bsd.parallel.mk file.
This targets provide atomic locking/unlocking technique to lock/unlock
a directory specified by ${_parv_DIR_TO_LOCK} variable.

Log:
[new_feature] ${PKG_DBDIR} and ${.CURDIR} specific lock/unlock
[fixed] do-lock do-unlock targets are depricated
It is possible to lock/unlock ${PKG_DBDIR} and ${.CURDIR}
For loop generates directory specific variable:
_parv_PKG_DBDIR_DO_LOCK - lockf command to lock ${PKG_DBDIR}
_parv_.CURDIR_DO_LOCK - lockf command to lock ${.CURDIR}
_parv_PKG_DBDIR_LOCK_SEQ, _parv_.CURDIR_LOCK_SEQ - sequences of
commandes passed to ${SH} lockf command argument.
e.g. lockf .lock_file ${SH} -c '_parv_PKG_DBDIR_LOCK_SEQ'
_parv_PKG_DBDIR_DO_UNLOCK, _parv_.CURDIR_DO_UNLOCK - lockf =
command
to unlock directories.

[fixed] bsd.parallel.mk: Changes of LOCK file mod. ps instead of pgrep.
feedBack messages.
bsd.parallel.mk: Is included in bsd.port.mk. Hence PKG_DBDIR is =

include <bsd.commands.mk> is unnecessary either.
"ps" command is more appropriate for PID searching.
.lock file mod is changed to 777. To allow open access.
More clear feedback messages.
