    Fix quadratic runtime when push parsing HTML start tags

Make sure that htmlParseStartTag doesn't terminate on characters for
which IS_CHAR_CH is false like control chars.

In htmlParseTryOrFinish, only switch to START_TAG if the next character
starts a valid name. Otherwise, htmlParseStartTag might return without
consuming all characters up to the final '>'.

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.
