Subject: res_pjsip: config option 'timers' can't be set to 'no'
X-Git-Tag: 13.4.0-rc1~157

res_pjsip: config option 'timers' can't be set to 'no'

When setting the configuration option 'timers' equal to 'no' the bit flag was
not properly negated. This patch clears all associated flags and only sets the
specified one. pjsip will handle any necessary flag combinations. Also went
ahead and did similar for the '100rel' option.
