Support for GTM-Proxy reconnection
This commit adds support for GTM-Proxy reconnection.
After promoting a GTM-Standby instance, it is possible
to reorientate Proxy worker threads to the newly-promoted
GTM instance.
Implemented in gtm_ctl, GTM reconnection uses USR1/USR2 to signal
GTM-Proxy main thread or worker threads.
If a worker thread receives a USR1 signal, it transmits it to the main thread.
After main thread has received USR1 signal, it signals worker threads with USR2.
Signal handling is managed by longjump.
A new keyword "reconnect" has been added in gtm_ctl.
Ex:
gtm_ctl reconnect -S gtm_proxy -D $PROXY_DATA -o '-s $STANDBY_HOST -t $STANDBY_PORT'
It is expected that new connection parameters to GTM are specified in string -o.
Implementation by Koichi Suzuki
