13811ec82e stand/fdt: Fallback to name + ".dtbo" if we fail to load name
This behavior also matches a Linux-ism by allowing fdt_overlays to specify
names of overlays without an extension, e.g. fdt-overlays="sunxi-h3-h5-emac"

If we fail to load the file given by a name in fdt_overlays, try again with
".dtbo" appended to it. This still allows overlays to lack .dtbo extension
if user prefers it and just adds a fallback cushion.

Future work could move this from a hard-coded ".dtbo" to a loader.conf(5)
configuration option.

25f0135c49 Add /boot/overlays to runtime pkg, fix distrib-dirs METALOG generation
/boot/overlays was recently added without belonging to a package. It's only
used by bootloaders at the moment, so add it to the 'runtime' package to get
added with ubldr and friends.

Fix distrib-dirs METALOG generation while we're here. History elsewhere
seems to indicate that bapt@ fixed this to pull in all attributes from
mtrees while generating the METALOG. This fix got clobbered somewhere later,
so restore it.

bc3d87fd59 Increment the route table gen count after a modify
Increment the route table generation count after modifying a
route.  This signals back to TCP connections that they need to
update their L2 caches as the gateway for their route may have
changed.  This is a heavier hammer than is needed, strictly
speaking, but route changes will be unlikely enough that the
performance effects of invalidating all connection route caches
should be negligible.

dbeab32f94 Invalidate inpcb LLE cache if cached route is invalidated
When the inpcb route cache is invalidated after a change to the
routing tables, we need to invalidate the LLE cache as well.
Previous to this change packets for the connection would continue
to use the old L2 information from the old L3 gateway, and the
packets for the connection would likely be blackholed.

1a55e1d038 Fix 64-bit booke kernel builds after the ldscript changes
Commits r326203 and r326978 broke 64-bit booke kernels by introducing a 1MB
zero-pad between the ELF header and the start of the kernel.  This didn't
cause a build failure, but caused kernels to need to be loaded into memory
1MB lower, which could easily break scripts expecting previous behavior.
This change matches the similar change made to AIM in r327358.

libregex context. It's easy enough to bring in the needed parts that can
work in a libregex world, so do so.

b37f6c9805 Add libregex, connect it to the build
libregex is a regex(3) implementation intended to feature GNU extensions and
any other non-POSIX compliant extensions that are deemed worthy.

These extensions are separated out into a separate library for the sake of
not cluttering up libc further with them as well as not deteriorating the
speed (or lack thereof) of the libc implementation.

libregex is implemented as a build of the libc implementation with LIBREGEX
defined to distinguish this from a libc build. The reasons for
implementation like this are two-fold:

1.) Maintenance- This reduces the overhead induced by adding yet another
regex implementation to base.

2.) Ease of use- Flipping on GNU extensions will be as simple as linking
against libregex, and POSIX-compliant compilations can be guaranteed with a
REG_POSIX cflag that should be ignored by libc/regex and disables extensions
in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when
implemented in this fashion.

Tests are added for future functionality, but left disconnected for the time
being while other testing is done.
