Rename boot1's wcslen to ucs2len, which we can't use in userland
because wchar in userland is unsigned, not short. Move it into
efichar.c. Also spell '* 2' as '* sizeof(efi_char)' and add 1 for the
trailing NUL to transition the FreeBSD boot env vars to being NUL
terminated on the same line...

Make efichar.c routines available to libefi as well as
libefivar. Define LIBEFI when building so we can conditionally include
stand.h vs the normal userland stuff.
Add libefi to the list of libraries we'll link in. Move EFI table

Move the efi_main routine out of libefi into sys/boot/efi/loader.
Since boot1 has its own efi_main routine, this effectively prevents
boot1 from linking with libefi. By moving it out, we can share code
better (though though some refactoring with boot1's efi_main and
loader.efi's efi_main is definitely in order).

The current read from network is working from up to down - we have some
protocol needing the data from the network, so we build the buffer space
for that protocol, add the extra space for headers and pass this buffer
down to be filled by nif get call in hope, we have guessed the incoming
packet size right. Amazingly enough this approach mostly does work, but
not always...
So, this update does work from down to up - we allocate buffer (based
on MTU or frame size info), fill it up, and pass on for upper layers.
The obvious problem is that when we should free the buffer - if at all.
In the current implementation the upper layer will free the packet on error
or when the packet is no longer needed.
While working on the issue, the additional issue did pop up - the bios
implementation does not have generic get/put interface but is using pxe
udpsend/udpreceive instead. So the udp calls are gone and undi interface
is implemented instead. Which in turn means slight other changes as we
do not need to have duplicated pxe implementation and can just use dev_net.
To align packet content, the actual read from nic is using shifted buffer by
ETHER_ALIGN (2).

As we provide the disk size verification and correction via disk_ioctl
and disk state provided by disk_open(), we can not share the partition
state in disk_devdesc structure. Also the sharing does make a lot of sense
with ufs, as only one partition is open at any given time, but zfs pools
do keep the disk devices open.

Add a new 'netproto' variable which can be set for now to
NET_TFTP or NET_NFS (default to NET_NONE)
From the dhcp options if one sets the root-path option to:
"ip:path", the loader will consider it is booting over NFS
(meaning same behaviour as the default current behaviour)
if the dhcp option "tftp server address" is set (option 150)
the loader will consider it is booting over tftpfs, it will then
consider the root-path options with 2 possible case
1. "path" then the IP of the tftp server will be the one passed by
the option 150, and the files will be retrieved under "path" on the tftp
server
2. "ip:path" then the IP of the tftp server will be the one passed in
the option "overwritting the IP from the option 150.
We could not "abuse" the rootpath option in the form or tftp://ip:path because
this is already used for other purpose by iPXE preventing any chainload from
iPXE to the FreeBSD loader.
Given at each open(), the loader loops over all available filesystems and keep
the "best" error, we needed to prevent tftpfs to fallback on nfs and vice versa.
the tftpfs and nfs implementation in libstand now return EINVAL early if
