While already powerful, it's quite often one wants to read and write
some specific GPT partition, and manually resolving the sectors and
plugging these into either a XML file or the command line is tedious and
error prone.
Allow partition names in the address specifier of the "read" and "write"
command line actions, and when these are used read the GPTs across all
physical partitions to resolve the physical partition, start sector and
sector count for the operation.
This allow us to do things like:
qdl prog_firehose.elf write abl_a abl2esp.elf write abl_b abl2esp.elf

There are a number of scenarios where one just want to write a binary
file directly to some specific location on the target, such as writing a
full disk image to LUN 0. Similarily (although not as frequent) one just
want to dump a few sectors of data for inspection.
So far the recommended way to do this has been to craft a program.xml
or a read.xml file and feed to QDL, but this is annoying.
Add support for writing/reading binary data straight to/from the device
by the means of just specifying the "write" or "read" commands on the
QDL commandline, e.g.:
qdl prog_firehose.elf write 0 debian.img

The sparse image format is defined in little endian, not in network
order, so we should not invoke ntohs()/ntohl() when reading them.
Further, the various constants are defined in host order, so we
shouldn't ntohs()/ntohl() them either.
This also implies that the code only works for little endian host
systems today.
Drop all the ntohs()/ntohl() conversions for now, to clean out the
incorrect conversions. The task to convert from little to host is left
as an exercise for the future.
While rewriting sparse_chunk_header_parse() the large if statement is
swapped for a select, to improve readability with a single successful
exit at the end and scattered exit returns throughout.

The unsparsed chunk size is expressed in units of blk_sz. For RAW chunks
this is then limited to (just under) 32-bits due to the total_sz
(sparsed chunk size), but FILL and DONT_CARE can be much bigger.
But doing the size calculation on the 32-bit integers overflows and any
upper bits are lost, and the unsparsed result is wrong. So, switch this
to 64-bit instead.
It's unclear what happens if we pass a larger num_sectors to the
programmer, so this limitation is left, and checked for.

When the sparse image parser finds a RAW chunk, it queries the current
file offset in the sparse image and store this for the programming
phase. But the offset is stored in a 32-bit unsigned int, so when the
sparse image passes 4GB the program entries start to refer to the wrong
data.
Split the fill_value and offset into dedicated fields and give them both
their specific type, to avoid any confusion related to the size of these
data types.

Builds with multiple copies of the primary bootloader does not make
sense, but after successfully flashing all the partitions of such build
it makes more sense to make one of them bootable, at least more than
skipping the step and saying that none was found.

When parsing XML files the specified binary to be flashed may not be
present. The default behaviour of QDL is to ignore missing file. This is
sometimes undesireble.
This patch changes the default behaviour. If the file to be flashed
can't be found qdl will exit with error. An optional flag --allow-missing
is introduced. It will allow to skip missing files during flashing procedure.
Default value of the flag is false.

Previously the message would be printed that the tag gets ignored but in
reality the 'errors' variable will still be initialized as -EINVAL so
the if below would return an error.
[PROGRAM] unrecognized tag "zeroout", ignoring
qdl: program_load rawprogram0.xml failed
But since we want this qdl to error out on unrecognized tags, modify the
message and make it clear in the code that this is an error path.
