Summary:                    ast_close_fds_above_n off-by-one's
Description: 
Hi,

I was checking out the changes in 1.6.2.8rc1 and saw the
ast_close_fds_above_n edit in r256483.

http://svn.asterisk.org/svn/asterisk/branches/1.6.2/main/app.c

The function is called "above_n". Shouldn't then:
if ((x = strtol(entry->d_name, &result, 10)) && x >= n) {
be:
if ((x = strtol(entry->d_name, &result, 10)) && x > n) {


And, related, the usage in res_agi seems wrong too:

# wgrep . ast_close_fds_above_n | sed -e '/:void/d;s/[[:blank:]]\+//'
./apps/app_voicemail.c:ast_close_fds_above_n(STDOUT_FILENO);
./apps/app_dahdiras.c:ast_close_fds_above_n(STDERR_FILENO);
./apps/app_festival.c:ast_close_fds_above_n(0);
./apps/app_externalivr.c:ast_close_fds_above_n(STDERR_FILENO);
./apps/app_ices.c:ast_close_fds_above_n(STDERR_FILENO);
./apps/app_nbscat.c:ast_close_fds_above_n(STDERR_FILENO);
./apps/app_mp3.c:ast_close_fds_above_n(STDERR_FILENO);
./main/asterisk.c:ast_close_fds_above_n(STDERR_FILENO);
./main/asterisk.c:ast_close_fds_above_n(0);
./res/res_musiconhold.c:ast_close_fds_above_n(STDERR_FILENO);
./res/res_agi.c:ast_close_fds_above_n(STDERR_FILENO + 1);

# grep -B1 ast_close_fds_above_n ./res/res_agi.c
		/* Close everything but stdin/out/error */
		ast_close_fds_above_n(STDERR_FILENO + 1);
That should probably be ast_close_fds_above_n(STDERR_FILENO) like the
others.
