- 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.

Wipe out mergeinfo.

The transition to Subversion allows us to rename files without
repo-copy hacks.
Remove the test-number prefix from the name of the output files,
so that new test cases can be easily added.

Set magic fbsd:nokeywords property that allows files to bypass
keyword expansion. (file-specific replacement for CVSROOT/exclude)

Today SUN and GNU seds fully agree on test 5.3 and behave
in a more reasonable way than BSD sed does: they properly
close the range even if we branched over its end. No doubt,
the range `1,5' should not match lines from 9 through 14.

Reference results for sed.test (to be renamed into multitest.t).
I have verified these with GNU sed 4.1.5 (and in some cases with Solaris
sed) and they are identical, with the following exceptions:
5.3: The result is unspecified and BSD sed behaves differently.
6.3: GNU sed gets it wrong
7.1: GNU sed gets it wrong
7.8: BSD sed gets it wrong
