Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

QEMU compiles a list of data directories from various sources. When
consuming a QEMU binary it's useful to be able to get this list of
data directories: a primary reason is so you can list what BIOSes or
keymaps ship with this version of QEMU. However without reproducing
the method that QEMU uses internally, it's not possible to get the
list of data directories.
This commit adds a simple '-L help' option that just lists out the
data directories as qemu calculates them:
$ ./x86_64-softmmu/qemu-system-x86_64 -L help
/home/rjones/d/qemu/pc-bios
/usr/local/share/qemu
$ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help

FW CFG's primary user is QEMU, which uses it to expose configuration
information (in the widest sense) to Firmware. Thus the name FW CFG.
FW CFG can also be used by others for their own purposes. QEMU is
merely acting as transport then. Names starting with opt/ are
reserved for such uses. There is no provision, however, to guide safe
sharing among different such users.
Fix that, loosely following QMP precedence: names should start with
opt/RFQDN/, where RFQDN is a reverse fully qualified domain name you
control.
Based on a more ambitious patch from Michael Tsirkin.
