mozdevice 0.3.8 released

[Armen Zambrano G.]

Hello,
Below you can find the changes since 0.37.
I want to highlight that we have switched to structured logging in bug
1026710.

Bug 1037651 - Release mozdevice 0.38. r=ahal
Bug 1041533 - Update mozdevice to not reset global log level. r=armenzg

Bug 1026710 - Fix errors in output handling in devicemanagerADB.
Bug 1037642 - Fix assumption that we will be able to send all data in
devicemanagerSUT in one shot. r=mcote
Bug 1026710 - Make DeviceManagerADB use mozprocess to allow logging.

Up until now, mozdevice has been using subprocess. The switch gives us
the ability to log adb commands and its output. This will be mainly used
for the Firefox OS cert suite.
