[libvirt] [PATCH v5 0/3] vsh: Introduce new API for printing tables

Created new API for priting tables, mainly to solve alignment problems.
Implemented these test to virsh list. In the future, API may be
everywhere in virsh and virt-admin.
Also wrote basic tests for the new API, and corrected tests in virshtest
which are influenced by implementation of the API in virsh list.

Changes in v5:
- cleanup and merged code for calculating zero-width, nonprintable and combined
- replaced virBufferAddStr with virBufferAddChar in some places
- in tests moved code for setting correct locale
- fixed few leaks and unitialized values

Changes in v4:
- fixed width calculation for zero-width, nonprintable and combined
character. (pulled some code from linux-util)
- added tests for cases mentioned above
- changed usage of vshControl variables. From now on PrintToStdout calls
PrintToString and then prints returned string to stdout

Changes in v3:
- changed encoding of 3/3 patch, otherwise it cannot be applied

Changes in v2:
- added tests
- fixed alignment for unicode character which span more spaces
- moved ncolumns check to vshTableRowAppend
- changed arguments for functions vshTablePrint, vshTablePrintToStdout,
