Update version for 4.2.1 release

iotests/283: Use consistent size for source and target
The test case forgot to specify the null-co size for the target node. When adding a check to backup that both sizes match, this would fail because of the size mismatch and not the behaviour that the test really wanted to test.

-Variable Naming Conventions
---------------------------
-
-A number of short naming conventions exist for variables that use
-common QEMU types. For example, the architecture independent CPUState
-is often held as a ``cs`` pointer variable, whereas the concrete
-CPUArchState is usually held in a pointer called ``env``.
-
-Likewise, in device emulation code the common DeviceState is usually
-called ``dev``.
-
-Function Naming Conventions
---------------------------
-
-Wrapped version of standard library or GLib functions use a ``qemu_``
-prefix to alert readers that they are seeing a wrapped version, for
-example ``qemu_strtol`` or ``qemu_mutex_lock``.  Other utility functions
-that are widely called from across the codebase should not have any
-prefix, for example ``pstrcpy`` or bit manipulation functions such as
-``find_first_bit``.
-
-The ``qemu_`` prefix is also used for functions that modify global
-emulator state, for example ``qemu_add_vm_change_state_handler``.
-However, if there is an obvious subsystem-specific prefix it should be
-used instead.
-
-Public functions from a file or subsystem (declared in headers) tend
-to have a consistent prefix to show where they came from. For example,
-``tlb_`` for functions from ``cputlb.c`` or ``cpu_`` for functions
-from cpus.c.
-
-If there are two versions of a function to be called with or without a
-lock held, the function that expects the lock to be already held
-usually uses the suffix ``_locked``.
-
+When wrapping standard library functions, use the prefix ``qemu_`` to alert
+readers that they are seeing a wrapped version; otherwise avoid this prefix.
