Major infrastructure changes, part 2.

* Moved helpers, common and triggers dirs into xbps-src, where
  they belong.
* Renamed the templates dir to srcpkgs, it was so redundant before.
* Make it possible to add subpkgs with no restriction in names, for
  example udev now has a subpkgs called "libgudev". Previously
  subpkgs were named "${sourcepkg}-${pkgname}".
* xbps-src: changed to look for template files in current directory.
  That means that most arguments from the targets have been removed.
* xbps-src: added a reinstall target, to remove + install.
* xbps-src: do not overwrite binpkgs by default, skip them.

And more that I forgot because it's a mega-commit that I've been
working for some days already...

+# Hereafter should be "server" or "peer" statements to configure other
+# hosts to exchange NTP packets with. Peers should be selected in such
+# a way that the network path to them is symmetric (that is, the series
+# of links and routers used to get to the peer is the same one that the
+# peer uses to get back. NTP assumes such symmetry in its network delay
+# calculation. NTP will apply an incorrect adjustment to timestamps
+# received from the peer if the path is not symmetric. This can result
+# in clock skew (your system clock being maintained consistently wrong
+# by a certain amount).
+#
+# The best way to select symmetric peers is to make sure that the
+# network path to them is as short as possible (this reduces the chance
+# that there is more than one network path between you and your peer).
+# You can measure these distances with the traceroute(8)  program. The
+# best place to start looking for NTP peers for your system is within
+# your own network, or at your Internet Service Provider (ISP).
+#
+# Ideally, you should select at least three other systems to talk NTP
+# with, for an "what I tell you three times is true" effect.
