Refactor timer suspend portion of node.sleep (pmsleep) (#2287) 

* pmsleep refactor
* Shortened swtmr disabled message 
* Added swtimer debug module option to user_modules.h.
* Added comments to user_config.h.
* Fixed error in documentation for node.sleep()
* remove blank sntp.c that got added in during rebase onto dev(6218b92)
* Added #ifdefs around SWTIMER_REG_CB to prevent inclusion of disabled
code

/* swTimer.c SDK timer suspend API
*
* SDK software timer API info:
*
* The SDK software timer uses a linked list called `os_timer_t* timer_list` to keep track of
* all currently armed timers.
*
* The SDK software timer API executes in a task. The priority of this task in relation to the
* application level tasks is unknown (at time of writing).
*
*
* To determine when a timer's callback should be executed, the respective timer's `timer_expire`
* variable is compared to the hardware counter(FRC2), then, if the timer's `timer_expire` is
* less than the current FRC2 count, the timer's callback is fired.
*
* The timers in this list are organized in an ascending order starting with the timer
* with the lowest timer_expire.
*
* When a timer expires that has a timer_period greater than 0, timer_expire is changed to
* current FRC2 + timer_period, then the timer is inserted back in to the list in the correct position.
*
* when using millisecond(default) timers, FRC2 resolution is 312.5 ticks per millisecond.
*
*
* TIMER SUSPEND API INFO:
*
* Timer suspension is achieved by first finding any non-SDK timers by comparing the timer function callback pointer
* of each timer in "timer_list" to a list of registered timer callback pointers stored in the Lua registry.
* If a timer with a corresponding registered callback pointer is found, the timer's timer_expire field is is compared
* to the current FRC2 count and the difference is saved along with the other timer parameters to temporary variables.
* The timer is then disarmed and the parameters are copied back, the timer pointer is then
* added to a separate linked list of which the head pointer is stored as a lightuserdata in the lua registry.
*
* Resuming the timers is achieved by first retrieving the lightuserdata holding the suspended timer list head pointer.
* Then, starting with the beginning of the list the current FRC2 count is added back to the timer's timer_expire, then
* the timer is manually added back to "timer_list" in an ascending order.
* Once there are no more suspended timers, the function returns
*

/* swTimer.c SDK timer suspend API
*
* SDK software timer API info:
*
* The SDK software timer uses a linked list called `os_timer_t* timer_list` to keep track of
* all currently armed timers.
*
* The SDK software timer API executes in a task. The priority of this task in relation to the
* application level tasks is unknown (at time of writing).
*
*
* To determine when a timer's callback should be executed, the respective timer's `timer_expire`
* variable is compared to the hardware counter(FRC2), then, if the timer's `timer_expire` is
* less than the current FRC2 count, the timer's callback is fired.
*
* The timers in this list are organized in an ascending order starting with the timer
* with the lowest timer_expire.
*
* When a timer expires that has a timer_period greater than 0, timer_expire is changed to
* current FRC2 + timer_period, then the timer is inserted back in to the list in the correct position.
*
* when using millisecond(default) timers, FRC2 resolution is 312.5 ticks per millisecond.
*
*
* TIMER SUSPEND API:
*
* Timer registry:
* void sw_timer_register(void* timer_ptr);
* - Adds timers to the timer registry by adding it to a queue that is later
* processed by timer_register_task that performs the registry maintenance
*
* void sw_timer_unregister(void* timer_ptr);
* - Removes timers from the timer registry by adding it to a queue that is later
* processed by timer_unregister_task that performs the registry maintenance
*
*
* int sw_timer_suspend(os_timer_t* timer_ptr);
* - Suspend a single active timer or suspend all active timers.
* - if no timer pointer is provided, timer_ptr == NULL, then all currently active timers will be suspended.
*
* int sw_timer_resume(os_timer_t* timer_ptr);
* - Resume a single suspended timer or resume all suspended timers.
* - if no timer pointer is provided, timer_ptr == NULL, then all currently suspended timers will be resumed.
*

## tmr.resume()
Resume an individual timer.
Resumes a timer that has previously been suspended with either `tmr.suspend` or `tmr.suspend_all`
#### Syntax
`tmr.resume(id/ref)`
#### Parameters
`id/ref` timer id (0-6) or object, obsolete for OO API (→ [`tmr.create()`](#tmrcreate))
#### Returns
`true` if timer was resumed successfully
#### Example
```lua
--resume timer mytimer
mytimer:resume()
--alternate metod
tmr.resume(mytimer)
```

!!! Warning
This function suspends ALL active timers, including any active timers started by the NodeMCU subsystem or other modules. this may cause parts of your program to stop functioning properly.
