* [timer] multiple microseconds timer support
* Remove TimerSchedulerLocator, Timer inherit from Ip6Locator instead to get TimerScheduler.
* Add separate UsecTimer and UsecTimerScheduler for multiple microseconds timer support.
* [timer] refine Timer names
* Rename alarm header files to alarm-milli.h and alarm-micro.h
* Rename alarm APIs to start with otPlatAlarmMilli and otPlatAlarmMicro
* Rename Timer classes to TimerMilli/TimerMilliScheduler and TimerMicro/TimerMicroScheduler
* [Timer] Refactor Timer code structure
* Create TimerBase and TimerSchedulerBase class for common functions;
* Use TimerMilli/TimerMicro and TimerMilliScheduler/TimerMicroScheduler for different functions;
* Define AlarmApi, so then TimerMilliScheduler/TimerMicroScheduler could use different AlarmApi.
This commit new configuration option `enable-multiple-instances` and
its corresponding option `OPENTHREAD_ENABLE_MULTIPLE_INSTANCES`. When
enabled OpenThread supports handling of multiple instances. By default
this is disabled.
This commit also adds two optimizations for single instance case to
simplify the code and also help reduce memory/RAM usage:
(1) OpenThread objects/classes typically keep a reference to a higher
level object (e.g., many classes keep track of owning `ThreadNetif`)
to be able to access other objects/methods within OpenThread class
hierarchy. In single instance mode, the reference member variables are
removed and instead global functions are used to access the singleton
objects from one class to the other. To implement this, a group of
`<Object>Locator` classes are defined (e.g., `ThreadNetifLocator`,
etc.) which are then used as base class of other OpenThread classes.
(2) OpenThread objects which provide a callback/handler (e.g.,
`Timer`, `Tasklet`, etc.) have `void *mContext` member variable which
is used to keep track of the owner of the object. In single instance
mode the `mConext` member variables are removed since the owner is
expected to be a singleton and can be uniquely determined from the
callback function.
To implement this, two changes are made: First the handler methods are
modified to provide a reference to the object (e.g., `Timer` handler
will provide a `Timer &aTimer` as a parameter of its handler
callback). Second, a new base class `Context` is introduced which
hides the implementation providing an arbitrary context information. A
new static method `GetOwner(aContext)` is added to classes which own a
callback providing objects. This method help convert a `Context` to
the reference of the owner class object.

This commit adds support for the dynamic log level selection. Config
option `OPENTHREAD_CONFIG_ENABLE_DYNAMIC_LOG_LEVEL` can be used to
enable/disable this feature (default setting is disabled).
Note that the `OPENTHREAD_CONFIG_LOG_LEVEL` specifies the log level at
compile/build time. The dynamic log level feature (if enabled) only
allows decreasing log level from the compile time setting.
This commit also adds `SPINEL_PROP_DEBUG_NCP_LOG_LEVEL` as a new
spinel property to control the log level. The set/get handlers for
this property along with its documentation are also added.
This commit modifies some of the log related macros/methods so
to harmonize them all to require an `otInstance` as their first
argument.
