Add the --verbose global option, which is made available as the
App.verbose property.
Some functions still take a verbose parameter, but the type of these
parameters is converted from bool to bool|None. The idea is that, if
they are None, their verbosity falls back to the global default.

The code below lib.distro, as left behind by the previous commit, is
geared towards being directly used as a command-line API. This commit
introduces the abstract base class Distro, a proxy for
distribution-specific interactions. The proxy abstracts distro
specifics into an API with proper method prototypes, not
argparse.Namespace contents, and can thus be more easily driven by
arbitrary code.
The Distro class is initialized with a member variable of type
ExecContext, another new class introduced by this commit. It is
designed to abstract the communication channel to the distribution
instance. Currently only one specialization exists, Local, which
interacts with the distribution and root file system it is running
in, but is planned to be subclassed to support interaction via SSH,
serial, chroot, or chains thereof.

Add the command distro.CmdRebootRequired, adding support for "distro
reboot-required". The command exits with status code 1 if a reboot is
required and 0 otherwise.
