[Buildroot] [RFC] Bootloader cleanup work

Hello,
Since I didn't get a lot of feedback on my latest "target/ cleanup
status" e-mail, dated April, 4th, I'm sending the different remaining
parts of the work I've done so far.
This part is the bootloader cleanup part. I think it needs more review
and testing than the filesystem cleanup I've done (especially the
U-Boot code). Here is a summary of the changes :
- Instead of spreading all bootloader's code in various directories
in target/, it is now gathered in a boot/ directory
- In terms of configuration, a new top-level configuration item is
available to configure bootloaders, instead of hiding them in
"Target filesystem support"
- Support for yaboot has been removed.
- Support for U-Boot has been considerably simplified, with much
fewer configuration options. I'd appreciate if people using the
removed options could tell us why they are useful in their
projects.
- Support for grub, grub2 and syslinux has been slightly
cleaned-up. More work is needed on grub2 to make it really useful.
Please tell me what you think about this, and whether I should
continue to push this.
Best regards,
Thomas
