freeipa/tests/i18n.py
John Dennis 689bea6575 text unit test should validate using installed mo file 
We use custom gettext classes (e.g. GettextFactory &
NGettextFactory). We should exercise those classes with an installed
binary mo file to demonstrate we are actually returning the expected
translated strings for all strings defined as being translatable.

The test logic in install/po/test_i18n.py was recently enhanced to
make this type of testing easier and more complete.
tests/test_ipalib/test_text.py should import the new i18n test support
and run it.

Previously tests/test_ipalib/test_text.py made a feeble but incomplete
attempt to do the above but even that was often not run because the
test would skip because the necessary test files were not available
unless they had been manually created in the install/po subdir. It is
now possible to correct those deficiencies in the test.

This patch does the following:

* Moves the location of i18n test code and adjust references to it.
  install/po/test_i18n.py was moved to tests/i18n.py. This permits
  tests/test_ipalib/test_text.py to import the i18n test utilities
  in a clean fashion. The Makefile in install/po now calls this
  same file.

* Modfies test function in test_i18n.py to accept function pointers
  for retreiving a translation.

* Imports test_i18n.py from the install/po directory in the tree

* Creates a tmp directory for the test localedir

* Parses the current ipa.pot file in install/po and generates
  a test po and mo file with special unicode markers. It installs
  the test mo file in the tmp localedir. This is accomplished by
  calling create_po() from the test_i18n.py file.

* If any of the above does not work it raises nose.SkipTest with
  the reason, and skips the test.

* It sets up functions to get a translation and a plural translation
  via our text.GettextFactory class and text.NGettextFactory class
  respectively. This are the functions we use intenally to get
  translations. It set the localdir and lang which are used by those
  classes to match our test configuration. It then runs a validation
  test on every translation and it's plural found in the test.po file
  by calling po_file_iterate and passed it the function pointers to
  our internal routines.

* At the conclusion of the test it cleans up after itself.

Note: extraneous files are not created in the tree, only a tmp
directory is utilized.

Validating msgid's in C code was insufficient.

* Make the discovery of format conversions much more robust by authoring
  a new function parse_printf_fmt() that is able to discover each
  format conversion in a string and break it into it's individual
  subparts. One of those subparts is the argument selector index. In c
  code we need to know if the argumenet selector index is present to
  know if translator can reorder the substitution strings.

  This replaces the simplistic python_anonymous_substitutions_regexp
  which was insufficient to deal with other programming languages
  (e.g. c).

* Add get_prog_langs() function to return the set of programming
  languages a msgid appears in. This is necessar because the msdid
  validation is programming language specific.

We test our translations by taking the original untranslated string
(e.g. msgid) and prepend a prefix character and then append a suffix
character. The test consists of asserting that the first character in the
translated string is the prefix, the last character in the translated string
is the suffix and the everything between the first and last character exactly
matches the original msgid.
We use unicode characters not in the ascii character set for the prefix and
suffix to enhance the test. To make reading the translated string easier the
prefix is the unicode right pointing arrow and the suffix left pointing arrow,
thus the translated string looks like the original string enclosed in
arrows. In ASCII art the string "foo" would render as:
-->foo<--
