commit 42d85d1293b2753f3f200de0e960bacef0c973c7

    fserve: Fix a buffer read overrun in _fs_client_access
    
    https://bugs.freedesktop.org/show_bug.cgi?id=83224
    
    Found by clang's Address Sanitizer
    
    	crac.num_auths = set_font_authorizations(&authorizations, &authlen,
    						 client);
    	/* Work around bug in xfs versions up through modular release 1.0.8
    	   which rejects CreateAC packets with num_auths = 0 & authlen < 4 */
    	if (crac.num_auths == 0) {
    	    authorizations = padding;
    	    authlen = 4;
    	} else {
    	    authlen = (authlen + 3) & ~0x3;
    	}
    	crac.length = (sizeof (fsCreateACReq) + authlen) >> 2;
    	crac.acid = cur->acid;
    	_fs_add_req_log(conn, FS_CreateAC);
    	_fs_write(conn, (char *) &crac, sizeof (fsCreateACReq));
    	_fs_write(conn, authorizations, authlen);
    
    In the case in the report, set_font_authorizations setup authorizations as a
    34 byte buffer (and authlen set to 34 as one would expect). The following
    block changed authlen to 36 to make it 4byte aligned and the final _fs_write()
    caused us to read 36 bytes from this 34 byte buffer.
    
    This changes the incorrect size increase to instead use _fs_write_pad which
    takes care of the padding for us.

    FreeType: Correct an allocation size
    
    Found by clang static analysis:
        Result of 'calloc' is converted to a pointer of type 'int', which is
        incompatible with sizeof operand type 'int *'
    
    This is likely benign because the old size was larger on any platform where
    sizeof(int) <= sizeof(void *), which is everywhere.

    bdfReadCharacters: Allow negative DWIDTH values
    
    The fix for CVE-2015-1804 prevent DWIDTH to be negative.
    However, the spec states that "DWIDTH [...] is a vector indicating the
    position of the next glyph’s origin relative to the origin of this glyph."
    
    So negative values are correct.
    
    Found by trying to compile XTS.
