Though it looks wrong that rtl_allocateMemory(0) == 0.

Add --bzip2 and --xz options to select the compression. Both options
can be used togetger to generate both types of tarballs in one call.
XZ compession is used by default.

Also renamed "lo*build" strings to "lo*core" to fit the current name
of the top level source directory.

Mimic Hungarian Excel's key bindings:

* inserting current date is Ctrl-'.'
* inserting current time is Ctrl-Shift-'.'

This eliminates the need to store the assigned doc pointer to cross-check
against whenever the edit engine is initialized.  It's cleaner this way
& fdo#43614 still remains fixed.

There should only be one active edit view while the user is typing
into a cell, or else it crashes when an external input method is
being used to input values (such as Japanese).

* New offapi com.sun.star.configuration entities to access the complete
  configuration read-only or read/write...
* ...configmgr adapted to support those new services/singletons...
* ...new unotools/configuration.hxx is the type-safe C++ plumbing on top of
  that...
* ...officecfg now generates C++ headers to access all the properties and sets
  given in the .xcs files...
* ...and svl's asiancfg.cxx exemplarily makes use of the new
  officecfg/Office/Common.hxx to access the configuration.
* There is still TODOs:  For one, see those listed in
  officecfg/registry/cppheader.xsl.  For another, at least a notification
  mechanism for the new read-only configuration access and the C++ wrapper is
  missing.

This should fix the Windows build, while keeping the
gb_Helper_abbreviate_dirs_native working in custom targets.
