Set date and time formats back to what they were before CLDR

While CLDR brings us a good and up to date source data to generate locales for
all databses we are using for locales, it is not the case of LC_TIME. Where it
does not defines the informations we need.

Put back all the date and time formats from the old locales.
Make it statically for now (in order to be able to merge it now into
11.0-RELEASE). The generation tools will be updated soon.

That gives us time to properly work on LC_TIME during the 12 timeframe.

While here fix abbreviated month for af_ZA (which are already fixed in CLDR
data upstream)

In locales where AP/PM was not defined before CLDR data, remove again the AP/PM
informations

For locales where AP/PM was defined before CLDR data, keep the CLDR information
which was properly translated.

MFC after: 3 days

- Prefer to use %d over %e where the day of the month should be zero
filled.
- Since %e means the day of the month as well, regard %e as same as %d
in md_order.

Regenerate timedef:

For Russian:
- Convert AM/PM which are badly formatted in CLDR to replace it by the proper
cyrillic
- Add a dependency on Text::Iconv so non unicode get the proper encoding for
AM/PM
- fix the date format having 'r.,' and convert it to 'r.' (also fixed in Bulgarian)

For All:
- Use complete Day of Week instead of the abbreviated one
