Don't bake all of CC/CPP/CXX into CFLAGS

This change strips out all of the cross-compiler arguments, (-target,

doesn't infect the build and subsequently the test.

Add comments noting why this logic is being added, and why the logic in

directory(3): Deprecate readdir_r(). Clarify dirent buffers.

In existing implementations including FreeBSD, there is no reason to use
readdir_r() in the common case where potentially multiple threads each list
their own directory. Code using readdir() is simpler.

What's more, lthough readdir_r() can safely be used on FreeBSD because
NAME_MAX is forced to 255, it cannot be used safely on systems where
{NAME_MAX} is not fixed. As a concrete example, FAT/NTFS filenames can be up
to 255 UTF-16 code units long, which can be up to 765 UTF-8 bytes.

Deprecating readdir_r() in POSIX has been proposed in
and glibc wants to deprecate it as well.

Netboot: allow both tftpfs and nfs in both pxeboot and loader.efi

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
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
'netproto' for that purpose.

Add some locking to sc_cngetc().

Keyboard input needs Giant locking, and that is not possible to do
correctly here.  Use mtx_trylock() and proceed unlocked as before if
we can't acquire Giant (non-recursively), except in kdb mode don't
even try to acquire Giant.  Everything here is a hack, but it often
works.  Even if mtx_trylock() succeeds, this might be a LOR.

Keyboard input also needs screen locking, to handle screen updates
and switches.  Add this, using the same simplistic screen locking
as for sc_cnputc().

Giant must be acquired before the screen lock, and the screen lock
must be dropped when calling the keyboard driver (else it would get a
harmless LOR if it tries to acquire Giant).  It was intended that sc
cn open/close hide the locking calls, and they do for i/o functions
functions except for this complication.

Non-console keyboard input is still only Giant-locked, with screen
locking in some called functions.  This is correct for the keyboard
parts only.

When Giant cannot be acquired properly, atkbd and kbdmux tend to race
and work (they assume that the caller acquired Giant properly and don't
try to acquire it again or check that it has been acquired, and the
races rarely matter), while ukbd tends to deadlock or panic (since it
does the opposite, and has other usb threads to deadlock with).

The keyboard (Giant) locking here does very little, but the screen
locking completes screen locking for console mode except for not
detecting or handling deadlock.

Create a hook 'post-initialize' for people that want to define
something (perhaps in loader.rc.local) that can read in .conf files
after all the other .conf files have been read and override settings
in them. This is quite handy if the .conf file name is determined
while the loader is running, but might be generically useful for other
things. If this hook exists, call it, otherwise don't do anything.

Doing it in these functions ensures that this file is reliably
read. It also works around a defect in forth where s" isn't allowed
outside a function (well, in a compile context) leading to gross
workarounds if one were to hack loader.rc like:

: maybe-some-func s" some-func" sfind if execute else drop then ;

which somehow seems worse. Though I'm sure there's some clever forthy
way of doing that with a macro.

Fix keyboard polling "on/off" to support recursion.  vt depends on
this, and sc will soon depend on it again.

The on/off request is passed without modification to lower layers,
so the bug was smaller in this layer than in in lower layers (the
sequence on;on;off left polling off when it should be on, but the
sequence on;on;off;on;off...  doesn't allow the interrupt handler
to eat the input after an "off" that should't turn off polled mode,
provided lower layers don't have the bug, since this layer is virtual.

The bug was small in lower layers too.  Normally everything is Giant
locked for keyboards, and this locks out the interrupt handler in
on;on;off;on;off... sequences.  However, PR 211884 says that fixing
this bug in ukbd in r303765 apparently causes the eating-by-interrupt

Start adding locking to sc_cngetc().

Restore an splx() lost in r228644.  We aren't nearly ready to remove
spl's.  They give hints about missing locking.  This lost one was
misplaced.  Dropping it early for convenience gave race windows for
accesses to the fkey buffer.  Giant locking accidentally fixed this
for non-console cases.

Put the spl's around the whole function.  Since there are many returns
that would need splx() just before them for a direct fix, split the
function into a wrapper that does the spl's and a "locked" function
that does the work.

Return earlier when no keyboard is attached to match the ordering in a
planned version.  This breaks the dubious feature of returning keys
from the fkey buffer after the keyboard has gone away.  Losing the keys
wouldn't matter, but we keep them too long now.
