99ac8154ff Provide libdl.
Create libdl.so.1 as a filter for libc.so.7 which exports public dl*
functions. The functions are resolved from the rtld instead, the goal
of creating library is to avoid errors from the static linker due to
missed libdl. For static binaries, an empty .o is compiled into
libdl.a so that static binaries still get dl stubs from libc.a.

Right now lld cannot create filter objects, disable libdl on arm64
when binutils are not used.

d0ab0ec2fa Fix Makefiles which override LIBDIR to not add incorrect dependencies into .depend.
This fixes these cases which would rebuild every time:
    make[6]: /usr/obj/usr/src/libexec/rtld-elf/tests/libpythagoras/.depend, 1: ignoring stale .depend for /usr/obj/usr/src/tmp/usr/tests/libexec/rtld-elf/libm.a
    make[6]: /usr/obj/usr/src/lib/libxo/tests/encoder/.depend, 1: ignoring stale .depend for /usr/obj/usr/src/tmp/usr/tests/lib/libxo/libxo.a
    make[7]: /usr/obj/usr/src/lib/libthr/tests/dlopen/dso/.depend, 1: ignoring stale .depend for /usr/obj/usr/src/tmp/usr/tests/lib/libthr/dlopen/libpthread.a

The problem is that some Makefiles will override LIBDIR to where they want
their library to install.  bsd.libnames.mk will then use ${LIBDIR} to define
where *existing* libraries are.  This then leads to looking for the
libraries in the *target* place rather than the *expected* place.

We may want to expand this (and all of the other *DIR variables in bsd.own.mk)
into something like what Ports has, a PREFIX and a LOCALBASE.  PREFIX being
where things are being installed to and LOCALBASE being where they already are.

For now store the default expected LIBDIR into LIBDIR_BASE and use that for
library locations.

d49a5ddd04 Create libefivar library. This library aims to provide
the same API as the GPL'd version of this library. It implements the common
Linux API for programatically manipulating UEFI environment varibales using
the UEFI Runtime Services the kernel provides. It replaces the old efi
library since it is programmed to a different interface, but retails the
CHAR16 to UTF-8 and vice versa conversion routines. The new name is to match
Linux program's expectations.

ec21434933 Renaming libifc to libifconfig in response to feedback on initial commit of
this library. Sticking to 'libifconfig' (and 'ifconfig_' as function prefix)
should reduce chances of namespace collisions, make it more clear what the
library does, and be more in line with existing libraries.

d14b24ef84 Add libifc, a library implementing core functionality that exists in ifconfig(8) today.
libifc (pronounced lib-ifconfig) aims to be a light abstraction layer between
programs and the kernel APIs for managing the network configuration.
This should hopefully make programs easier to maintain, and reduce code
duplication.

Work will begin on making ifconfig(8) use this library in the near future.

This code is still evolving. The interface should not be considered stable until
it is announced as such.

	It was only being emitted on a transition to the HEALTHY state.
	That made it impossible for zfsd to take actions based on drives

	It compared the new state to vdev_prevstate, which is the state that
	the vdev had the last time it was opened.  That doesn't make sense,
	because a vdev can change state multiple times without being
	reopened.

	vdev_set_state contains logic that will change the device's new
	state based on various conditions.  However, the statechange event
	was being posted _before_ that logic took effect.  Now it's being
	posted after.

After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.

d6fb489498 Start on a new library (libsysdecode) that provides routines for decoding
system call information such as system call arguments.  Initially this
will consist of pulling duplicated code out of truss and kdump though it
may prove useful for other utilities in the future.

This commit moves the shared utrace(2) record parser out of kdump into
the library and updates kdump and truss to use it.  One difference from
the previous version is that the library version treats unknown events
that start with the "RTLD" signature as unknown events.  This simplifies
the interface and allows the consumer to decide how to handle all
non-recognized events.  Instead, this function only generates a string
description for known malloc() and RTLD records.

7f911abe54 Add support to libkvm for reading vmcores from other architectures.
- Add a kvaddr_type to represent kernel virtual addresses instead of
  unsigned long.
- Add a struct kvm_nlist which is a stripped down version of struct nlist
  that uses kvaddr_t for n_value.
- Add a kvm_native() routine that returns true if an open kvm descriptor
  is for a native kernel and memory image.
- Add a kvm_open2() function similar to kvm_openfiles().  It drops the
  unused 'swapfile' argument and adds a new function pointer argument for
  a symbol resolving function.  Native kernels still use _fdnlist() from
  libc to resolve symbols if a resolver function is not supplied, but cross
  kernels require a resolver.
- Add a kvm_nlist2() function similar to kvm_nlist() except that it uses
  struct kvm_nlist instead of struct nlist.
- Add a kvm_read2() function similar to kvm_read() except that it uses
  kvaddr_t instead of unsigned long for the kernel virtual address.
- Add a new kvm_arch switch of routines needed by a vmcore backend.
  Each backend is responsible for implementing kvm_read2() for a given
  vmcore format.
- Use libelf to read headers from ELF kernels and cores (except for
  powerpc cores).
- Add internal helper routines for the common page offset hash table used
  by the minidump backends.
- Port all of the existing kvm backends to implement a kvm_arch switch and
  to be cross-friendly by using private constants instead of ones that
  vary by platform (e.g. PAGE_SIZE).  Static assertions are present when
  a given backend is compiled natively to ensure the private constants
  match the real ones.
- Enable all of the existing vmcore backends on all platforms.  This means
  that libkvm on any platform should be able to perform KVA translation
  and read data from a vmcore of any platform.

This also reworks how the list of 'host allowed' libraries is determined

For usr.bin/readelf use the same hack, as libelf and libdward, to bring in
the needed sys/ headers for host builds.  This has not yet been a problem due
to readelf not being built as a host tool in buildworld.  This is possible
in the meta build though when building the toolchain.
