Warner Losh 2b46091032 efivar: Really look for labels for the provider with right efimedia
The prior code mistakently thought that the g_consumer that hung off the
provider we found were the right thing to use to find all the glabel
aliases for this node. However, the only way to find that is to iterate
through all the geoms that belong to the glabel geom class, looking for
those geoms with the same name as the provider with the right efimedia.
Do this in a way that caches glabel class, and allows for it to be
absent. Tighten the filter for mounted filesystems to only look
for the ones that are mounted on /dev/.. since the rest of the code
assumes that.

Warner Losh 57d5ca4eeb efivar: support device paths as well as mounted paths in path_to_dp
In path_to_dp, allow passing in either the actual device path "eg
/dev/foo/bar" or the path where the device is mounted (say
/mnt/baz/bing). In the former case we'll assume the path within the
device is nothing (the relpath). In the latter, we'll take from the
mount point on down as the relpath.

Warner Losh 49fd6affdb efivar: Allow NULL paths in build_dp
Allow there to be NULL paths in buildp. This lets us return the device
path to the partition, as well as to files on the partition.

Warner Losh ccf2121d59 efivar: Try harder to find label's efimedia
If there's no efimedia attribute on the provider, and the provider's a
glabel, then find the 'parent' geom. In this case, the provider's name
is label-type/name, but the geom's label will that of the underlying
device (eg ada0p1). If it is, recurisvely call find_geom_efimedia with
the geom's name, which shuold have the efimedia attribute.

Warner Losh 52467047aa Regularize the Netflix copyright
Use recent best practices for Copyright form at the top of
the license:
1. Remove all the All Rights Reserved clauses on our stuff. Where we
   piggybacked others, use a separate line to make things clear.
2. Use "Netflix, Inc." everywhere.
3. Use a single line for the copyright for grep friendliness.
4. Use date ranges in all places for our stuff.

Warner Losh 670a4056e2 Need to convert '/' back to '\' when creating a path. Ideally, this
would be filesystem type dependent, but that's difficult to accomplish
and it's unclear how the UEFI firmware will cope. Be conservative and
make boot loaders cope instead.

Warner Losh 167b7a41ff Set dp to NULL when we free it, and tree a NULL dp as an error
condition. This should prevent a double free. In addition, prevent a
leak by freeing dp each loop and when we're done.

Warner Losh 09ee5d8ab6 Create a function to translate UEFI paths to unix paths
efivar_device_path_to_unix_path translates from UEFI to Unix
efivar_unix_path_to_device_path translates from Unix to UEFI

At present, only HD() device types are supported (both GPT and
MBR). CdRom and floppy devices aren't supported. ZFS isn't supported
because there's no way in the UEFI standard to specify a ZFS datastore.
Network devices aren't supported either.

Three forms of Unix path are accepted: /path/to/file (for a mounted
filesystem), //path/to/file (uses the EFI partition on the same disk
as /), and dev:/path/to/file (for unmounted filesystem). Two forms are
produced (the first and last).
