* doc/apibuild.py doc/elfgcchack.xsl: revamped the elfgcchack.h format to cope with gcc4 change of aliasing allowed scopes, had to add extra informations to doc/libxml2-api.xml to separate the header from the c module source. * *.c: updated all c library files to add a #define bottom_xxx and reimport elfgcchack.h thereafter, and a bit of cleanups. * doc//* testapi.c: regenerated when rebuilding the API Daniel
