- 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.

Copy lib/libc/stdtime to contrib/tzcode/stdtime for the proper split
of contributed code and FreeBSD specific code.

MFV of tzcode2009e:

Upgrade of the tzcode from 2004a to 2009e.

Changes are numerous, but include...

- New format of the output of zic, which supports both 32 and 64
bit time_t formats.

- zdump on 64 bit platforms will actually produce some output instead
of doing nothing for a looooooooong time.

- linux_base-fX, with X >= at least 8, will work without problems related
to the local time again.

The original patch, based on the 2008e, has been running for a long
time on both my laptop and desktop machine and have been tested by
other people.

After the installation of this code and the running of zic(8), you
need to run tzsetup(8) again to install the new datafile.

Merge changes from the tzcode2004a import. Wherever possible I tried to bring
us closer to the vendor branch.

Assume __STDC__, remove non-__STDC__ code.

Fix the style of the SCM ID's.
I believe have made all of libc .h's as consistent as possible.

Correct factor-of-10 error in INT_STRLEN_MAXIMUM() calculation.

Merge the recently-imported tzcode96h distribution (libc portion). The
part that does zic(8)/zdump(8) is still yet to be imported (but the old
zic and zdump will work just fine with these header files and the
data format has not changed).

Removed false copyrights...

Added in appropriate Berkeley copyright and RCS Id: string

Closes PR#doc/536

The European Commission went out and invented a new sort of summer-time
changeover, so we have to extend the format of timezone files (in a backward-
compatible way, of course). This probably means that libc needs a minor
version number bump before 2.2 is released (or maybe not).

Use latest Arthur Olson timezone code rather than that supplied with
4.4. The code is almost identical to the 4.4 versions, but this organization
should make it easier to merge new versions in the future.

This commit was generated by cvs2svn to compensate for changes in r2708,
which included commits to RCS files with non-trunk default branches.
