    Fix random dropping of characters on dumping ASCII encoded XML

Fix a bug in xmlCharEncOutput return value which will cause
xmlNodeDumpOutput to drop characters randomly.

xmlCharEncOutput returns zero if the length of the input buffer is
zero but ignores the fact that it may already encoded the input buffer
and the input's length is zero due to the fact that xmlEncOutputChunk
returned -2 errors and underlying code tries to fix the error by
encoding the input.

xmlCharEncOutput is collecting the number of bytes written to the
output buffer but is returning zero instead of the total number of
bytes in this situation. This commit will fix this issue by returning
the total number of bytes instead. So the xmlNodeDumpOutput will also
continue writing and will not stop due to the fact that it mistakenly
thinks the output buffer is not changed in that iteration.

Fixes #314

To build on an Unixised setup:
   ./configure ; make ; make install
   if the ./configure file does not exist, run ./autogen.sh instead.
To build on Windows:
   see instructions on win32/Readme.txt

To assert build quality:
   on an Unixised setup:
      run make tests
   otherwise:
       There is 3 standalone tools runtest.c runsuite.c testapi.c, which
       should compile as part of the build or as any application would.
       Launch them from this directory to get results, runtest checks 
       the proper functioning of libxml2 main APIs while testapi does
       a full coverage check. Report failures to the list.
