Implement a suggestion found in ms_main.c, namely to add the equivalent
of fprintf to m_libcprint.c  The new functions are called 
VG_(fdprintf) and VG_(vfdprintf) as they take in a file descriptor as
first argument.
Change massif and cachegrind to use those functions.
In massif, also eliminate the truncation of ip_desc. If does not appear
that ms_print has a buffer size limitation anywhere.
