Use the Global Offset Table to find the location of main in crt1. With
lld the old code would point to main@plt, however ld.bfd fails to link
when main is in a shared library.
Fix this by using the GOT address to find main as it works with both
lld and bfd.

ld.bfd doesn't understand elf64-aarch64 but does have
elf64-littleaarch64. Switch to this so we can link kboot with it.
While here switch to the single format version. We are unlikely to
support booting from a big-endian Linux.

When linking with ld.bfd it complain with the following:
/usr/local/bin/aarch64-unknown-freebsd14.0-ld: start.o: relocation
R_AARCH64_ABS32 against `__data_size' can not be used when making a
shared object
Fix this by marking the __data_size with ABSOLUTE. This returns a
non-relocatable value which appears to be the same behaviour of lld.

If we fail to change the vlan id we have to undo the removal (and vlan id
change) in the error path. Otherwise we'll have removed the vlan object from the
hash table, and have the wrong vlan id as well. Subsequent modification attempts
will then try to remove an entry which doesn't exist, and panic.
Undo the vlan id modification if the insertion in the hash table fails, and
re-insert it under the original vlan id.

- glabel requires write permission on device
- filesystems first need to be unmounted for new labels to persist

- if the affected device node holds the filesystem root, single-user

When the if_vlan(4) interface has not been fully configured, i.e., a
bare interface without a physical interface associated with it,
retrieving the current settings of it and unconditionally overwriting
`params` will result in losing vlandev settings in `params`. That will
lead to failing to associate the if_vlan(4) interface with the requested
physical interface and the false report 'both vlan and vlandev must be
specified'.
Fix that by checking if the vlan interface has been fully configured.
The basic VLAN test is slightly modified to cover this case.
