Implement generic timer functions in src/timer.c Changes: * Implement patty_timer_expired() to determine if a timer has expired or has gone negative * Implement patty_timer_cancel() to set a timer to zero * Implement patty_timer_start() to initialize a timer, add a specified number of milliseconds, and ensure a target timer (such as the server timer) is set for at least that value as well * Implement patty_timer_tick() to subtract an elapsed time value from a timer * Remove functions specific to each timer in src/sock.c, as those can now be handled generically by src/timer.c * Replace calls to patty_ax25_sock_timer_t1_*() with patty_timer_*() calls instead; reference the struct timeval objects directly within the sock (for the time being, pending opaque structures)

Implement patty_timer type Changes: * Implement patty_timer type to store both a struct timeval and a bitfield for indicating timer state; currently, this only holds the PATTY_TIMER_RUNNING flag to indicate whether a timer has been stopped (irrespective of its "expired" status) * Remove 'target' argument from patty_timer_start(); instead, rely on select() polling every 1s to cause events to trigger at a regular interval * Make patty_timer_expired() return false if PATTY_TIMER_RUNNING is not set * Implement patty_timer_stop() to clear the PATTY_TIMER_RUNNING flag of a timer * Make patty_timer_clear() set all fields to zero, including clearing the PATTY_TIMER_RUNNING flag
