loader: Add preload operation to fs_ops
When we load an ELF file (kernel or module) we do seek(2) a lot to
parse/load the different sections of the ELF file.
Protocol like TFTP suffers a lot from this as there is no resume or
a way to start the tranfer from a specified offset in the file.
fs_preload is added to help those protocol.
Call preload just after opening the ELF file that we need to load so
the underlying method can cache the hole file and then read/lseek operations
are faster.

loader: tftp: Don't let tftp timeout
When we load a kernel or module we open/close it a few times.
Since we're using the same port number each time and that we requested
the same file the ACK that we send are valid on the server side and the
server send us the file multiple times.
This makes tftp loading time very inconsistant due to the UDP "flood" that
we have to process.

loader: Set twiddle globaldiv to 16 by default
Booting FreeBSD on an EC2 c5.xlarge instance, the loader "twiddles"
810 times over the course of 510 ms, a rate of 1.59 kHz. Even accepting
that many systems are slower than this particular VM and will take
longer to boot (especially if using spinning-rust disks), this seems
like an unhelpfully large amount of twiddling when compared to the
~60 Hz frame rate of many displays; printing the twiddles also consumes
roughly 10% of the boot time on the aforementioned VM.
Setting the default globaldiv to 16 dramatically reduces the time spent
printing twiddles to the console while still twiddling at roughly 100
Hz; this should be ample even for systems which take longer to boot and
consequently twiddle slower.
Note that this can adjusted via the twiddle_divisor variable in
loader.conf, but that file is not processed until nearly halfway
through the loader's runtime.

servip is set from bootp bp_siaddr (if present) and rootip is
set immediately from servip in tha sane bootp code.
However, the common/dev_net.c does only set rootip (based on
url processing etc). Therefore, we should also use rootip in tftp
reader.
Fixes hung tftp based boot when bp_siaddr is not provided.
