7b0d05d56d loader: loader_lua can run command_more twice
When we quit pager, the return value 1 is returned and command_more()
interprets it as error.

when lua loader gets error from command, it will try to
interpret it once more, so we get the same file shown once more.

There is no reason why we should return error from command_more().

0d13f5343f Only trigger read-ahead if two adjacent blocks have been requested.
The change makes block caching algorithm to work better for remote
media on low-BW/high-delay links.

This cuts boot time over IP KVMs noticeably, since the initialization
stage reads bunch of small 4th (and now lua) files that are not in
the same cache stripe (usually), thus wasting lot of bandwidth and
increasing latency even further.

The original regression came in 2017 with revision 87ed2b7f5. We've
seen increase of time it takes for the loader to get to the kernel
loading from under a minute to 10-15 minutes in many cases.

5e4279a8f3 loader: fix multiboot loading on UEFI
The Xen kernel has no symbol tables, so calling lookup_symbol against
it triggers the following Divide by Zero fault:

Loading Xen kernel...
/boot/xen data=0x2809c8+0x149638 |
!!!! X64 Exception Type - 00(#DE - Divide Error)  CPU Apic ID - 00000000 !!!!

Fix lookup_symbol to prevent the #DE fault from happening if the
symbol table is not loaded and also fix loadfile_raw to mark multiboot
kernels as relocatable, since the only multiboot kernel supported is
Xen and was already unconditionally booted as relocatable.

97cbd5e722 loader: open file list should be dynamic
Summary:
Open file list is currently created as statically allocated array (64 items).
Once this array is filled up, loader will not be able to operate with files.
In most cases, this mechanism is good enough, but the problem appears, when
we have many disks with zfs pool(s). In current loader implementation, all
discovered zfs pool configurations are kept in memory and disk devices open -
consuming the open file array. Rewrite the open file mechanism to use
dynamically allocated list.

f75caed644 amd64 UEFI loader: stop copying staging area to 2M physical
On amd64, add a possibility to activate kernel with staging area in place.
Add 'copy_staging' command to control this.  For now, by default the
old mode of copying kernel to 2M phys is retained.  It is going to be
changed in several weeks.

On amd64, add some slop to the staging area to satisfy both requirements
of the kernel startup allocator, and to have space for minor staging data
increase after the final size is calculated.  Add a new command
'staging_slop' to control its size.

Improve staging area resizing, in particular, reallocate it anew if
we cannot grow it neither down nor up.

dbdf2b52f5 loader: support.4th resets the read buffer incorrectly
Large nextboot.conf files (over 80 bytes) are not read correctly by the
Forth loader, causing file parsing to abort, and nextboot configuration
fails to apply.

Simple repro:

nextboot -e foo=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
shutdown -r now

That will cause the bug to cause a parse failure but shouldn't otherwise
affect the boot.  Depending on your loader configuration, you may also
have to set beastie_disable and/or reduce the number of modules loaded
to see the error on a small console screen.  12.0 or CURRENT users will
also have to explicitly use the Forth loader instead of the Lua loader.
The error will look something like:

Warning: syntax error on file /boot/loader.conf.local
foo="xxxxxxxxxxxxxxnextboot_enable="YES"
                                    ^
/boot/support.4th has crude file I/O buffering, which uses a buffer
'read_buffer', defined to be 80 bytes by the 'read_buffer_size'
constant.  The loader first tastes nextboot.conf, reading and parsing
the first line in it for nextboot_enable="YES".  If this is true, then
it reopens the file and parses it like other loader .conf files.

Unfortunately, the file I/O buffering code does not fully reset the
buffer state in the reset_line_reading word.  If the last file was read
to the end, that doesn't matter; the file buffer is treated as empty
anyway.  But in the nextboot.conf case, the loader will not read to the
end of file if it is over 80 bytes, and the file buffer may be reused
when reading the next file.  When the file is reread, the corrupt text
may cause file parsing to abort on bad syntax (if the corrupt line has
<>2 quotes in it), the wrong variable to be set, no variable to be set
at all, or (if the splice happens to land at a line ending) something
approximating normal operation.

The bug is very old, dating back to at least 2000 if not before, and is
still present in 12.0 and CURRENT r345863 (though it is now hidden by
the Lua loader by default).

Suggested one-line attached.  This does change the behavior of the
reset_line_reading word, which is exported in the line-reading
dictionary (though the export is not documented in loader man pages).
But repo history shows it was probably exported for the PNP support
code, which was never included in the loader build, and was removed 5
months ago.

One thing that puzzles me: how has this bug gone unnoticed/unfixed for
nearly 2 decades?  I find it hard to believe that nobody's tried to do
something interesting with nextboot, like load a kernel and filesystem,
which is what I'm doing.

- The freebsd-boot partiton is located farther than the first 2 TiB of

e713d3a013 boot: fix OBJS to not include BTX's crt0.o
According to comments in the Makefile, to make pxeboot work we need to
have crt0.o first. This is needed because the simplified loader in
pxeboot assumes that the startup code is at offset 0 in this binary. In
normal booting, the start address can be obtained from headers of the
binary, but since pxeboot encodes this as a pure binary, it has no way
of knowing where that is and assumes 0. Added comments to that effect
in the Makefile.

We've done this by adding it to OBJS before all the other .o's are
added. However, there's a problem. This also adds it to the CLEANFILES
variable, which causes it to be removed from multiple places. The
dependencies may also cause it to be re-built at a time that's after
boot2 is built. This causes installs to fail because at install time
boot2 is considered to be out of date and the programs to rebuild it are
no longer in the path.

Cope with this problem by just adding it to LDFLAGS instead.

42cd37dfbd gptboot.efi: Add man page
Add a man page for gptboot.efi. Describe when and how to use this as it differs
from the BIOS cases. Include cross reference for the preferred method described
in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to
the other.

This man page was heavily copied from the gptboot.8 man page by Warren Block.
They are different enough to need separate man pages for clarity, but there's
enough similarity that I worry about the duplication. In the really long term,
gptboot(8) will disappear, so having the same info here will help when that
day comes. In the short to medium term, the information is likely to not
change in gptboot(8) and any changes to gptboot.efi(8) will be easier to
make in a separate copy.

loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have
referenced gptboot.efi(8) from there.

Visible needs to be a function. Looks like I tested the wrong thing.
