- Consistently use reg_idx to represent an index into all PCI
configuration space registers and bar_idx to represent an index into
just the BAR list. (e.g. bar_idx 0 is at reg_idx 0x10).
- Add a PciBarIndex type to make the related APIs clearer versus using
usize directly.
- Remove Default impl for PciBarConfiguration and fix up the previous
callers to fully configure the BAR type instead of depending on the
defaults.
- Omit "get_" from the names of getter functions to follow Rust

These parameters multiplied the number of type arguments to build_vm
unnecessarily and complicated the thread of execution in the programmers
head. Closures also complicate the borrow rules, making things much
harder to change.
This change uses the results of the closures (e.g. PCI devices, IRQ
chips) as parameters instead. The rest of this change follows naturally
from pulling on that thread until tests pass.
As a result of the removal of several type arguments, the code size was
reduced by ~100KiB on a 5MiB build.

The current design of having the VDA instance outside of the Decoder was
mandated by the use of lifetimes on libvda Sessions, which have been
removed from libvda. So it is now possible for the Decoder to own its
VDA instance.
This makes sense in itself since there is no reason for the VDA instance
to also be used by someone else, but is also required to add support for
non-libvda decoder backends.

This makes detect_image_type do a single read of size 4096 instead of
doing two smaller reads matching the size of the magic values. This
eliminates one source of misaligned disk access, which is needed to
enable O_DIRECT. It also reduces the number of reads required, although
this probably has very little, if any, performance impact.
In addition, the magic comparison is rewritten to make the endian
conversion more readable - the qcow2 magic number is written in big
endian and the Android sparse disk magic is little endian, but
previously this was unclear since the sparse comparison did a double
big-endian conversion to get to little endian.
