Update gettext packages to 0.19.2:

Version 0.19.2 - July 2014

* Bug fixes:
  - Fix xgettext crash in parsing empty string literals in C and Vala.
  - ChangeLog file is added back to the gettext infrastructure.  It was
    mistakenly removed in 0.19.
  - Autoconf macro trace in autopoint now works again with Autoconf 2.68
    or earlier.  It was a regression in 0.19.

Version 0.19.1 - June 2014

* Programming languages support:

  - Desktop Entry:
    msgfmt now always reads the po/LINGUAS file, regardless of whether
    the LINGUAS environment variable is set.  The variable can now be
    used to restrict the languages list read from the po/LINGUAS file.

  - Vala:
    Bug fix in xgettext handling of "//" in string literals.  This was
    a regression after the C-99 Unicode escape support.

* The po/Makevars.template file now contains the newly added variables.

* msgfmt now treats errors in the PO file header as non-fatal.  Since
  0.19 msgfmt started to abort on the fatal errors, but some
  translation systems are still not ready to supply valid headers.

* Future backward-incompatibilities:
  - In future Gettext versions, msgfmt will treat header errors as
    fatal and terminate the command execution.

Version 0.19 - June 2014

* Programming languages support:

  - Desktop Entry:
    xgettext and msgfmt now support .desktop files, used by desktop
    applications, as input and output.

  - GSettings:
    xgettext now supports GSettings schema file format used by GNOME
    applications.

  - JavaScript:
    xgettext now recognizes E4X (ECMA-357) constructs.

  - PHP:
    Single and double quotes around heredoc markers are now recognized.

  - Python:
    The acceptable format specifiers in the braced-syntax format
    strings are now limited to the Standard Format Specifiers, to
    reasonably avoid false-positives.

  - Scheme:
    The gettext shorthand form _"abc", used by GIMP script-fu, is now
    recognized by xgettext.

  - C and Vala:
    xgettext now recognizes C99-style Unicode character escapes.

* The --add-location option of msgattrib, msgcat, msgcomm, msgconv,
  msgen, msgfilter, msggrep, msgmerge, msguniq, and xgettext commands
  now takes an optional argument 'never', 'full', or 'file', to
  control the format of "#: ..." comments.

* msgfmt now has --source option to keep generated .java file when
  running in Java mode.

* msgattrib now has --empty option that sets msgstr to empty when
  clearing fuzzy flag.

* msgexec and msgfilter pass the plural information to subprocess
  through the environment variable MSG{EXEC,FILTER}_MSGID_PLURAL and
  MSG{EXEC,FILTER}_PLURAL_FORM.

* New built-in filters 'quot' and 'boldquot' have been added to
  msgfilter.  These filters convert Latin quotation marks ('...',
  "...") into Unicode quotation marks (for example, U+2018) if
  possible, similar to the sed commands used in po/Rules-quot and
  po/Rules-boldquot.

* The po/Makevars file has a couple of new options PO_DEPENDS_ON_POT
  and DIST_DEPENDS_ON_UPDATE_PO, that can be used to adjust the
  behavior of updating PO files on demand.

* xgettext now strips prefixed string before the comment tag.  This is
  useful to support C-style comment like this:

  /*
   * TRANSLATORS: first line
   * second line
   */

  In this example, the extracted comment does not contain "* " at the
  beginning of each line.

* libgettextpo library:
  - Memory leak fixes in the PO file parser.

* Documentation:
  - A complete example showing the use of GNU gettext in a GNOME 3
    application has been added.
