The international currency symbol (int_curr_symbol) has a mandatory
SPACE character as the last character.
Trim this space after reading it, otherwise this extra space will always
be printed when displaying the int_curr_symbol.
Fixes the output when the international currency format is selected
(%i).
Locale Format Before After
en_US.UTF-8 [%i] [USD 123.45] [USD123.45]
fr_FR.UTF-8 [%i] [123,45 EUR ] [123,45 EUR]
Note that the en_US.UTF-8 locale states that no space should be printed
between the currency symbol and the value (sep_by_space = 0).

Avoid an out-of-bounds access when trying to set the space_char using an
international currency format (%i) and the C/POSIX locale.
The current code tries to read the SPACE from int_curr_symbol[3]:
currency_symbol = strdup(lc->int_curr_symbol);
space_char = *(currency_symbol+3);
But on C/POSIX locales, int_curr_symbol is empty.
Three implementations have been examined: NetBSD[1], Darwin[2], and
Illumos[3]. Only NetBSD has fixed it[4].
Darwin and NetBSD also trim the mandatory final SPACE character after
reading it.
Locale Format Darwin/NetBSD FreeBSD/Illumos
en_US.UTF-8 [%i] [USD123.45] [USD 123.45]
fr_FR.UTF-8 [%i] [123,45 EUR] [123,45 EUR ]
This commit only fixes the out-of-bounds access.

get it from sys/types.h, but bool isn't defined there for non-kernel
builds and this otherwise kernel-only file is used for the physmem test

They are used when ASLR is not applied.
The need for adjusting is due to rtld direct exec mode puts ld-elf.so.1
at the PIE load address, and this address must not conflict with the
default linker' load address for non-PIE binaries. Otherwise rtld in
direct mode cannot activate image. Example of implicit failure is ldd(1)
refusing to run.

In order to safely reuse excluded memory when it's reserved for special
purpose, we need to test whether or not the memory has been reserved
early in boot. physmem_excluded will return true when the entire range
is excluded, false otherwise.

There is some hardware which can't be completely reset to release the
memory it is using(so far only the GICv3 on arm has fit this
bill). Since that meory needs to be reserved by the OS for that
hardware's later use of it, create defines for code that will parse that
memory table. Otherise the system may allocate the memory for block I/O,
network packets, etc which will lead to memory corruption.
When booting via Linux's kexec protocol, it will add this table to the
EFI systbl's cfgtbl array. While the mechanism to pass 'configuration'
is standardized, these specific tables are not documented except in the
Linux source. Include comments gleened from its study.

It's possible to have files with odd permissions in the tmproot (or
sysroot), causing rm to prompt for each one during e.g. buildworld.
Add -f to forcibly delete these.

Get rid of split's home-grown logic for growing the buffer; arbitrarily
breaking at LONG_MAX bytes instead of 65536 bytes gives us much more
wiggle room. Additionally, we'll actually fail out entirely if we can't
fit a line, which makes noticing this class of problem much easier.

Currently libvmmapi provides a way to get a list of the allowed ioctls
on the vmm device file, so that bhyve can limit rights on the device
file fd. The interface is rather strange: it allocates a copy of the
list but returns a const pointer, so the caller has to cast away the
const in order to free it without aggravating the compiler.
As far as I can see, there's no reason to make a copy of the array, but
changing vm_get_ioctls() to not do that would break compatibility. So
this change just introduces a better interface: move all rights-limiting
logic into libvmmapi.
Any new operations on the fd should be wrapped by libvmmapi, so also
discourage use of vm_get_device_fd(). Currently bhyve uses it only when
limiting rights on the device fd.
No functional change intended.

We recently got rid of the explicit INP_TIMEWAIT state, this has caused some
minor breakage to both rack and bbr. Basically the timewait check that was
in tcp_lro.c is now gone. This means that compressed_ack and mbuf_queued
packets will arrive at TCP without going through tcp_input_with_port(). We need
to expand the check that was stripped to look at the tcp_state (t_state) and
not "LRO" packets that are in the TCPS_TIMEWAIT state.
