current is broken

It seems current source is broken if MB is enabled.

gcc -c -I../../../src/interfaces/libpq -I../../../src/include -I../../../src/interfaces/libpq -O2 -Wall -Wmissing-prototypes -Wmissing-declarations pg_dump.c -o pg_dump.o
pg_dump.c: In function `isViewRule':
pg_dump.c:267: parse error before `int'
pg_dump.c:268: `len' undeclared (first use in this function)
pg_dump.c:268: (Each undeclared identifier is reported only once
pg_dump.c:268: for each function it appears in.)
pg_dump.c:268: warning: implicit declaration of function `pg_mbcliplen'
make[3]: *** [pg_dump.o] Error 1

The problem is:

#ifdef MULTIBYTE
int len;
len = pg_mbcliplen(rulename,strlen(rulename),NAMEDATALEN-1);
rulename[len] = '\0';
#else
:
:

Moreover, pg_mbcliplen cannot be used in frontend. It seems what we
need here is new backendside functiontion what does same as
pg_mbcliplen. Will look into this...
