- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Now that the portsnap buildbox is generating the raw bits for INDEX-10,
add it to the set of INDEX files built by portsnap.

Now that stable/7 is EOL, stop building INDEX-7.

Now that the portsnap buildbox is generating the raw bits for INDEX-9,
add it to the set of INDEX files built by portsnap.

Remove INDEX-6 from the default portsnap configuration file; the 6.x index
bits haven't been built since December 1st, although the mirrors are still
distributing the bits as they were at the EoL.

Add INDEX-8 to the default portsnap configuration file, and remove INDEX-5.
The Portsnap buildbox now generates teh bits needed for portsnap to produce
INDEX-8; and it hasn't built INDEX-5 for a long time, although the bits are
still distributed for an INDEX-5 from when FreeBSD 5.x reached its EoL.

Add support for specifying which INDEX files to build via portsnap.conf.

Add a warning pointing out that incomplete ports trees are not
supported and that users of REFUSE directives should update their
entire ports tree before asking for help on the mailing lists.

Teach portsnap how to ignore unwanted parts of the ports tree. A line
of the form "REFUSE foo" in portsnap.conf will result in parts of the
tree matching "^foo" being (a) not extracted by "portsnap extract", (b)
not updated by "portsnap update", and (c) not having any patches or new
ports downloaded by "portsnap fetch" or "portsnap cron". The example
shown in portsnap.conf demonstrates ignoring all the language categories.

As mentioned in portsnap.conf.5, the use of an imcomplete ports tree is
not officially supported; but this is something which many users have
requested, so I'm adding it anyway.

PR: bin/85619 (but not the patch provided therein)
MFC after: 1 month

Add portsnap to the base system. This is a secure, easy to use,
fast, lightweight, and generally good way for users to keep their
ports trees up to date.

This is version 0.9.4 from the ports tree (sysutils/portsnap) with
the following changes:
1. The experimental pipelined http code is enabled. No seatbelts
in -CURRENT. (^_^)
2. The working directory has moved from /usr/local/portsnap to
/var/db/portsnap (as discussed on -arch two days ago).
3. Portsnap now fetches a list of mirrors (distributed as DNS SRV
records) and selects one randomly. This should help to avoid the
uneven loading which plagues the cvsup mirror network.
4. The license is now 2-clause BSD instead of 3-clause BSD.
5. Various incidental changes to make portsnap fit into the base
system's build mechanics.
