Cleanup function xmlBufResetInput() to set input from Buffer
This was scattered in a number of modules, xmlParserInputPtr
have usually their base, cur and end pointer set from an
xmlBuf used as input.
* buf.c buf.h: add a new function implementing this setup
* parser.c HTMLparser.c catalog.c parserInternals.c xmlreader.c
use the new function instead of digging into the buffer in
all those modules
