netascii is obsolete and inefficient. It isn't even supported by many
clients. Better to use binary mode by default.

Some of the changes are in the libexec/tftpd directory, but to functions that
are only used by tftp(1) (they share some code).

On an RRQ, tftpd doesn't exit as soon as it's finished receiving a file.
Instead, it waits five seconds just in case the client didn't receive the
server's last ACK and decides to resend the final DATA packet.
Unfortunately, this created a 5 second delay from when the client thinks
it's done sending the file, and when the file is available for other
processes.
Fix this bug by closing the file as soon as receipt is finished.

Summary:
r329077 caused gcc to emit uninitialized use warnings. Attempting to
fix those warnings yielded the following warnings:
usr.bin/tftp/main.c: In function 'main':
usr.bin/tftp/main.c:181: warning: variable 'el' might be clobbered by
'longjmp' or 'vfork'
usr.bin/tftp/main.c:182: warning: variable 'hist' might be clobbered by
'longjmp' or 'vfork'
This is a known bug in gcc, found at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24239
Work around that by simply marking hist and el as static.

This bug was first reported 14 years ago. The problem was understood 8.5
years ago. A patch that is functionally identical to this one was proposed
almost 8 years ago and languished in the PR system / Bugzilla.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Prefer ${SRCTOP}/foo over ${.CURDIR}/../../foo and ${SRCTOP}/usr.bin/foo
over ${.CURDIR}/../foo for paths in Makefiles.

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

to print the stats were using an uninitialised variable. [1]
Fix trasnfer statistics in the "receive file" case - the statistics struct
was being cleared both before and after the initial connect to the remote
server. As a result, the printed time and calculated bandwidth covers
the time to connect ad well as the time to transfer the file. This may
not be ideal, but now at least matches the "send file" case.
