At present, the logic only tries backup URLs when an
actual download fails (bad internet connection or the
server is down).
If the main download succeeds, but it has a bad checksum,
the backup download is not attempted.
Since wrongly hashed files are to be assumed useless, we
may aswell delete and try the next file. This will guard
against the possibility of a vendor changing their file,
without changing the file name (non-versioned files, for
example, may be subject to such changes).

ME extraction didn't support unar (RAR format), for regular
extraction, after downloading a vendor file.
For bruteforce ME extraction, after extracting a vendor
archive, unar(RAR) and inno(innoextract) was not supported.
This patch fixes both issues. It should be noted that as of
now, the unar method has only been tested with certain HP
vendor updates, and it's currently not used on any of those.

I messed up the string, when I first did this.

Immediately after the last revision, which was a hacky
workaround to the problem, I realised the actual problem,
and the real solution:
In the switch block, check *backup* first. Then it breaks,
continuing on the iteration.
If it's variable for a main URL, it'll reliably go to the
next check in the block, whereas if it's backup, it'll
default to the first one in each case.
This bug has been annoying the sh*t out of me for ages,
and I've finally nailed it.

The script was actually downloading the backup, at
all times, for each given URL. The way we handle
this is quite buggy.
This patch is a workaround, a dirty hack in fact, but
it will do for now, because our backup URLs are always
wayback links where the original URL (matching the
correct main URL in the sources file) is always present,
in the URL.

Make it look like a normal web browser, downloading files.
Some HTTP servers might block Wget unless this is done.

This was an oversight on my part.
Should extraction fail, we must abort. This is in preparation
for addition of future mainboards, where further tweaking is
required in blobutil. This error check will warn us about it.

fixes ./build boot roms all
in detect_firmware(), "set" is used to get values from
configs, to know if things like ME/MRC are needed
on some "board" configs under resources/coreboot/, no
actual coreboot configs are provided, because they are
used as a reference (coreboot revision, tree name etc)
for actual boards, with actual coreboot configs
when attempting to build for such a board, running "set"
on such non-existent files would cause a non-zero exit,
when we want zero. the non-zero exit then caused the
build/boot/roms command to fail, when running "all" if
it found, for example, resources/coreboot/cros/ which
has the above problem, in this context
work around it by verifying that coreboot configs exist
for the given target name, in the blobutil download script.
if no such configs exist, then exit zero (success)
doing so is correct, because the script is intended to
do just that, erroring only if it is detected that blobs
are needed for a given board, but other errors occur; if
no coreboot configs exist, then no roms will be built and,
therefore, no blobs are needed

Since many boards use the same ME firmware, we could save
everyone's bandwidth and time by caching the update files.

This reverts commit a4ea2867319471d9fe7d4ee540881e0286b4d3cf.
The licensing audit has been abandoned. I will not be re-licensing
in bulk to MIT.
I can still use MIT license on new works, e.g. utilities, but there's
really no pressing need to re-license lbmk. It's just shell scripts,
and most of what it interacts with (coreboot, grub, seabios) is GPL
anyway.
So who cares?
Ferass's patch was removed due to refusal to re-license, but the
decision to re-license has been canceled.
I'm now aiming for a quick stable release.

make blobutil a symlink. Example of command changes:
./blobutil download x220_8mb
is now:
./update blobs download x220_8mb
The old command still works, for compatibility.
