parser.c: xmlParseCharData peek behavior fixed wrt newlines
requested to merge flavorjones/libxml2:flavorjones-fix-xmlParseCharData-read-boundary-bug-v2 into master
Previously, xmlParseCharData and xmlParseComment would consider 0xA to be unhandleable when seen as the first byte of an input chunk, and fall back to xmlParseCharDataComplex and xmlParseCommentComplex, which have different memory and performance characteristics.
Fixes #192 (closed)
