man: Do glob expansion with echo instead of ls
echo is a shell builtin, and always present. While ls usually works,
some upgrade scenarios need to have ls be a build to to work
correctly. Rather than add it as a build tool, use echo instead which is
always safe because sh is a build tool.

da: Stop the probing when periph invalidated in dadone_proberc
When READ CAPACITY fails, we call cam_periph_invalidate() for some
hopeless ASC/ASCQ combinations and then fall through to test the cache
state. This results in excess commands to the abandoned device that may
take a while to timeout and/or report confusing errors. Instead, call
daprobedone() when the periph is invalid to terminate the probe.

stand/efihttp: Support arbitrary http[N]://host[:port]/path devspecs
Until now, the "http" device only worked when firmware itself booted
loader.efi via EFI HTTP Boot: efihttp_dev_init() required a URI node on
the loader's own boot device path, and every fetch went to that same
server. Add a second form, using the parse_uri() helper from libsa/dev.c,
that works anywhere: http[N]://host[:port]/path (N is a network interface
unit, defaulting to 0). This lets a devspec like this be used as rootdev,
in loader.conf, or interactively, independent of how loader.efi itself
was booted.
Network configuration is shared, loader-wide state (the myip/netmask/
gateip/nameip globals from net.h): if something has already configured
them (e.g. tftp/nfs via net_open()), the http device just reuses those
values, applying them to EFI_IP4_CONFIG2_PROTOCOL as a static address. If
nothing has, it drives IP4Config2's own DHCP directly instead of calling
netdev's net_open(): net_open() opens the NIC's SNP
EFI_OPEN_PROTOCOL_EXCLUSIVE, which would disconnect the Mnp/Ip4/.../
HttpDxe driver chain this code depends on. That chain is also commonly

libsa: Add a generic URI-syntax devspec parser
Add parse_uri(), a helper for devices whose devspec can take a
"[N]://host[:port][/path]" form in addition to the traditional "N:path"
form. It returns EINVAL when devspec doesn't match that pattern, so a
caller's own dv_parsedev can fall back to the traditional form.
Un-static default_parsedev() so it can serve as that fallback.

loader.efi: For ipxe booting, fall back to md when ramdisk fails
Some UEFI firmwares do not contain the RamDisk protocol. When this
happens, load the file into a md disk instead. This is less desireable
than the RamDisk (since that allows better chain-booting options), but
sufficient to boot an image as a md device for FreeBSD. While most
severs have the RamDisk protocol enabled in their builds, I have two
IoT class boards from different manufacturers that do not. Since it
works just fine with this fallback, that's preferable.

loader: Small tweak to how md is configured
Only the EFI loader supports the md devices (as the moment). Create
LOADER_MD_SUPPORT and only try to compile md when that's true. For the
moment, also allow it when only MD_IMAGE_SIZE is defined, but that
will be dropped since LOADER_MD_SUPPORT is a superset.
