Correct baud rate is 38400. Confirmed with manufacturer, and with a winch on v1.02. Also confirmed w/ manufacturer that newest winches on v1.04 also use 38400. Removed if statement forcing baud rate of 115200 to be consistent with documentation, and to avoid issues in future if manufacturer changes baud rate again.
AP_Logger.h is a nexus of includes; while this is being improved over
time, there's no reason for the library headers to include AP_Logger.h
as the logger itself is access by singleton and the structures are in
LogStructure.h
This necessitated moving The PID_Info structure out of AP_Logger's
namespace. This cleans up a pretty nasty bit - that structure is
definitely not simply used for logging, but also used to pass pid
information around to controllers!
There are a lot of patches in here because AP_Logger.h, acting as a
nexus, was providing transitive header file inclusion in many (some
unlikely!) places.
