Subject: csdk: Relocate timerlib to c_common/octimer
X-Git-Tag: 1.3.0~368
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8e6f6b8f94dd9d1d01312ab5d6d972dd30bdfc11;p=platform%2Fupstream%2Fiotivity.git

csdk: Relocate timerlib to c_common/octimer

It never was an external library while it was located there,
the code is small enough to be part c_common utility library.

No functionnal changes were introduced, just reformated source.

Note, For Arduino, timer object is built using C++ compiler tricks,
that could be removed once support is dropped.

Bug: https://jira.iotivity.org/browse/IOT-1889
