Main/AudioAdapter+BandwidthControl+Machine+NetworkAdapter+ParallelPort+SerialPort+StorageController+USBDeviceFilter+USBDeviceFilters: Adjust rules when settings can be changed to allow as much as possible. Some changes restored the old rules (a previous change made the definition more restrictive), but many now allow changing settings when VM is saved or even at runtime when it is safe. Will resolve many complaints, especially when the GUI also is adapted accordingly.

Main/BandwidthControl: eliminate warning

6813 - MachineImpl use of server side wrappers + misc mods on other classes

6813 - formatting changes as needed - BandwidthControlImpl.cpp

Main/BandwidthControl+BandwidthGroup: fix an init bug which led to crashes when restoring snapshots (just one line, using the wrong "copy constructor"), and quite some comment fixes to talk about the right thing (and not show where the code was copied from)

Main/BandwidthControl: to me it seems we must not uninit the bandwidth groups here

Main/BandwidthControl: fix regression (iterator incremented twice), plus lots of whitespace cleanup

stage 1/8 of 6813 changes

Main: do not include VirtualBoxImpl.h from code ending in VBoxC (causes unnecessary rebuilds), and make sure that the code still builds with VBOX_WITH_RESOURCE_USAGE_API unset

Main: big API naming cleanup, use all caps acronyms everywhere, including SDK docs Frontends/VBoxManage: implement guestcontrol execute for new API, disabled by default

NetShaper: Runtime shaper disabling support (#5582)

Main/Bandwidth: server side limit validity check (#5582)

Main,VBoxManage,docs: bandwidth units changed to bytes (#5582)

Main/Medium: rework locking scheme to solve lock order violations and long GUI start up time caused by too much locking Main/all: Remove the enter and leave methods from write locks, they cause hard to find locking problems. Better solve them explicitly.

Main. QT/FE: fix long standing COM issue

Main: source re-org.
