Fix a recently introduced warning:

| :> make
| gcc -c  -I../os/unix -I../include   -funsigned-char -DTARGET=\"apache\" -pipe
| -O -pedantic -Wall -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
| -Wmissing-declarations -Wnested-externs -Winline `../apaci` http_main.c
| http_main.c:3485: warning: no previous prototype for `common_init'

I've checked it and it looks like a mistake from a recent commit, because
commot_init() is still a locally used function only:

| :> aps grep common_init
| ===> main/http_main.c
| static void common_init(void)
|     common_init();
|     common_init();
|     common_init();

Feel free to complain and reverse this again, but then please fix it in
addition to a prototype somewhere in the header files or at least at the start
of http_main.c, of course.
