This new default-enabled rc will generate a /etc/machine-id file if it
does not exist, and pre-fill it with a newly generated UUID of version 4
[2].
The file is generated in /var/db/machine-id and symlinked to
/etc/machine-id to allow for read-only root partitions.
This file is amongst other things used by libraries like GLib.
Bump FreeBSD version 1400076 to be able to easily add support for older
version of FreeBSD via a package.

Add new growfs_swap_size variable with a default value of the empty
string, along with comments on other settings. Used by the growfs
script.
Differential Revision: https://reviews.freebsd.org/D37464
The growfs_fstab script is a helper for the growfs script to add any
new swap partition to /etc/fstab on first boot. If growfs adds a
swap partition, it sets growfs_swap_pdev in the kenv. In this case,
after the root file system is read/write, if there is no swap partition
in the fstab, growfs_fstab adds growfs_swap as a swap partition to the
fstab. Also, it runs dumpon to add the swap partition (as this
happened earlier in the startup sequence).

Add the ability to create a swap partition in the course of growing
the root file system on first boot, enabling by default. The default
rules are: add swap if the disk is at least 15 GB (decimal), and the
existing root is less than 40% of the disk. The default size is 10%
of the disk, but is limited by the memory size. The limit is twice
memory size up to 4 GB, 8 GB up to 8 GB memory, and memory size over
8 GB memory. Swap size is clamped at vm.swap_maxpages/2 as well.
The new swap partition is labeled as "growfs_swap".
The default behavior can be overridden by setting growfs_swap_size in
/etc/rc.conf or in the kernel environment, with kenv taking priority.
A value of 0 inhibits the addition of swap, an empty value specifies
the default, and other values indicate a swap size in bytes.
By default, addition of swap is inhibited if a swap partition is found
in the output of the sysctl kern.geom.conftxt before the current root
partition, usually meaning that there is another disk present.
Swap space is not added if one is already present in /etc/fstab.
The root partition is read-only when growfs runs, so /etc/fstab can
not be modified. That step is handled by a new growfs_fstab script,
added in a separate commit. Set the value "growfs_swap_pdev" in kenv
to indicate that this should be done, as well as for internal use.
There is optional verbose output meant for debugging; it can only be
enabled by modifying the script (in two places, for sh and awk).
This should be removed before release, after testing on -current.

GCC warns about the non-literal format string passed to strftime(). A
warning here seems a bit odd as strftime() does not take varargs so
there is not a risk of missing args.
As PF now also supports dummynet but can not configure it on its own,

dma accepts mail from a local Mail User Agent (MUA) and delivers it
locally or to a smarthost for delivery. dma does not accept inbound
mail (i.e., it does not listen on port 25) and is not intended to
provide the same functionality as a full MTA like postfix or sendmail.
It is intended for use cases such as delivering cron(8) mail. which
is the default configuration and usage of sendmail in the default
setup of the base system.
In order to switch the default from sendmail to dma, we teach
mailwrapper to fallback on dma directly if the mailer.conf file cannot

to be of lower risk and is required to connect to legacy devices, so

for the default output. For '-a' (per-object needed printout) the
[preloaded] banner is kept.
Instead, use special format2 for printing the preloaded objects (and
vdso), which does not include DT_NEEDED, since there is no object
needing the printed one.
In this way, the output is more compatible with glibc.
Example:

Rtld locks from libthr defer signals delivery, which means that binding
is not possible while a signal handler is executed.
Binding might upgrade read-locked rtld_bind_lock to write-lock, if
symbol resolution requires loading filters. If a signal would be delivered
while rtld is in read-locked section, and signal handler needs binding
which upgrades the lock, for non-threaded image that uses default rtld
locks, we get the rtld data structures modified under the top-level
active rtld frame.
To correct the problem, mask signals for read-locking of default locks
in addition to the write-locking. It is very cheap now with
sigfastblock(2).
Note that the global state is used to track pre-locked state of either
sigfastblock(2) or signal mask (if sigfastblock(2) is administratively
disabled). It is fine for non-threaded images since there are no other
threads. But I believe that it is fine for threaded images using libc_r
as well, since masking signals disables preemption (I did not tested
it).
