The QLocale XML reader was passing datetime formats through a format
conversion despite the data being converted at the point where we read
it from CLDR. It turns out this was needed because the long date and
time formats in our hard-coded data for the C Locale object used CLDR
format strings, unlike all other Locale objects. Fix those two formats
in the C locale and remove the redundant processing step. This, in
turn, enables the parser to include the date and time formats in its
general handling of most fields that it reads.
This does not result in any change to the generated data QLocale uses
(although it does change the intermediate QLocale XML file).

The LDML spec includes a 'b' pattern character which is like the 'a'
pattern, for AM and PM, but would rather use noon and midnight
indicators for those specific times. We don't support those and using
am/pm will be right enough of the time to be better than simply
discarding this option, if it ever gets used (which it currently
isn't), so treat as an alias for 'a'. No locale in CLDR currently uses
this.
CLDR also has a 'B' specifiers for "flexible day periods", including
things like "at night" and "in the day". At present only zh_Hant uses
'B'. As a result, this change only affects zh_Hant's formats for time
and datetime, which only zh_Hant_TW uses - zh_Hant_HK overrides them
to use am/pm markers and zh_Hant_MO inherits that from
zh_Hant_HK. Based on this and user feed-back, I've opted to treat 'B'
as another synonym of 'a'.
This removes an entry from the time_format_data[] table (it happened
to occupy one whole twelve-character row), causing many other locales'
offsets into that table to be shifted by 12. Only zh_Hant_TW has an
actual change to which entry in the table it uses.
Added a test-case.

Rework the somewhat ad-hoc handling of format blocks. Instead of
converting one character at a time, then coming back to map contiguous
chunks of various lengths to Qt's best match, use the first
non-separator character to select a function that looks ahead to see
what to consume with it. Quoted text can be handled the same way, with
a look-ahead. This potentially allows for more flexible parsing in
future.
In the process, matching qlocale_mac.mm, treat all unquoted letters as
reserved. The LDML spec says:
Currently, A..Z and a..z are reserved for use as pattern characters
(unless they are quoted, see next item).
and its description of literal text explcitly says these reserved
characters are not to be understood as literals. Document the letters
we do know about as unsupported pattern characters, but don't do
anything specific to handle them. This transiently changes zh_TW's
"Bh" hour fields to plain "h" but an imminent commit will change that
again and there is no other change to data, so the locale data is not
regenerated in this commit, to save churn.
This makes the parsing front-end function more straightforward and
makes it easier to document the quirks of the different format letters
and the impedance mismatches between CLDR's and Qt's. In the process,
recognize C, like j and J, as special magic to ignore and harmonize
with what qlocale_mac.cpp's macToQtFormat() does, where it's right and
dateconverter.py differed. Document the need to stay in sync with this
last.

We can easily enough obtain the root of the present source tree using
the value of __file__, so might as well do so.

This commit extends functionality for QLocale::codeToLanguage()
and QLocale::languageToCode() by adding an additional argument
that allows selection of the ISO 639 code-set to consider for
those operations.
The following ISO 639 codes are supported:
* Part 1
* Part 2 bibliographic
* Part 2 terminological
* Part 3
As a result of this change the codeToLanguage() overload without
the additional argument now returns a Language value if it matches
any know code. Previously a valid language was returned only if
the function argument matched the first code defined for that
language from the above list.
[ChangeLog][QtCore][QLocale] Added overloads for codeToLanguage()
and languageToCode() that support specifying which ISO 639 codes
to consider.
