[xml] status of xmlBufEnd() and xmlBufContent()

[Petr Sumbera <petr sumbera oracle com>]

Hi,

are functions mentioned in subject public or not?

Code in libxml2-2.9.0/testapi.c calls them but they are not listed in 
libxml2-2.9.0/libxml2.syms.

The result is problem during linking:

-bash-4.1$ /bin/bash ./libtool --silent --tag=CC   --mode=link 
/ws/on12-tools/SUNWspro/sunstudio12.1/bin/cc -D_REENTRANT   -m32 -xO4 
-xchip=pentium -xregs=no%frameptr    -mt -D_LARGEFILE_SOURCE 
-D_FILE_OFFSET_BITS=64  -z defs -z direct -lpthread -o testapi testapi.o 
./libxml2.la -lpthread -lz   -lm  -lsocket -lnslUndefined 
        first referenced
 symbol                             in file
xmlBufEnd                           testapi.o
xmlBufContent                       testapi.o
ld: fatal: symbol referencing errors. No output written to .libs/testapi
