Release 0.2.6

Fix loading of initrd for FreeDesktop.org Boot Loader Specification
based images.

Release 0.2.5

This includes numerous improvements from Joe Richey
<[email protected]> which significantly improve the binary size and
the general code quality by removing unneeded dependencies.

0.2.4: linker.ld: Use explict program headers

This maps the file headers into readonly data, while preventing any
other sections from being generated. It also makes the file 8% smaller.

We also replace the marker symbols for {begin|end}_of_{text|data} with
symbols denoting the begining/end of the file itself.

Finally, we make an explict DISCARD section (based off of EDK2's
GccBase.lds to prevent any additional data from entering our binary).

0.2.3: efi: Implement writing to block device

Using the SectorWrite trait added to the block device implement writing
to the block device. This is useful for bootloaders that need to write
to the block device in order to be able support fallback booting.

In particular this enables the firmware to be used with Ubuntu 19.10
("eoan".)

0.2.2: main, pci: Try booting off all block devices on PCI bus

This requires a refactoring of the PCI device detection to take a
closure to invoke over all the devices that match the vendor/device
pair.

Fixes: #16
