16545cf5d5 Introduce the daemonfd function.
The daemonfd function is equivalent to the daemon(3) function expect that
arguments are descriptors. For example dhclient(8) which is sandboxed is
unable to open /dev/null to close stdio instead it's allows to fail
daemon(3) function to close the descriptors and then do it explicit in code.
Instead of such hacks we can use now daemonfd.

This API can be also helpful to migrate system to platforms like CheriBSD.

41ec95c47f Bump number that's an insane number of devices from 1,000 to 10,000. I
have access to machines that are pushing 400 devices. When 1,000 was
selected, it was rare to get even 40 or 50 devices. Bump the limit by
10x to keep up with the times.

87f69beea3 libsysdecode: Add a new ABI type, SYSDECODE_ABI_CLOUDABI32.
In order to let truss(8) support tracing of 32-bit CloudABI
applications, we need to add a new ABI type to libsysdecode. We can
reuse the existing errno mapping table. Also link in the cloudabi32
system call table to translate system call names.

While there, remove all of the architecture ifdefs. There are not
needed, as the CloudABI data types and system call tables build fine on
any architecture. Building this unconditionally will make it easier to
do tracing for different compat modes, emulation, etc.

6e16d0bc43 Rework alignment handling in __libc_allocate_tls() for Variant I of TLS layout.
There are two versions of variant I of TLS
- ARM and aarch64 uses original version of variant I here TP points to
  start of TCB followed by aligned TLS segment. Both TCB and TLS must
  be aligned to alignment of TLS section. The TCB[0] points to DTV vector
  and DTV values are real addresses (without bias).

- MIPS, PowerPC and RISC-V use modified version of variant I,
  where TP points (with bias) to TLS and TCB immediately precedes TLS
  without any alignment gap. Only TLS should be aligned. The TCB[0]
  points to DTV vector and DTV values are biased by constant value (0x8000)
  from real addresses.

Take all this in account when allocating memory for TLS structures.

6c093deeda Remove basename_r(3).
Now that the POSIX working group is going to require that basename(3)
and dirname(3) are thread-safe in future revisions of the standard,
there is even less of a need to provide basename_r(3). Remove this
function to prevent people from writing code that only builds on
FreeBSD and Bionic.

Removing this function seems to break exactly one port: sbruno@'s
qemu-user-static. I will send him a pull request on GitHub in a bit.
__FreeBSD_version will not be bumped, as any value from 2017 can be used
to test for the presence of a thread-safe basename(3)/dirname(3).

82241ed55c Optimize telldir(3)
Currently each call to telldir() requires a malloc and adds an entry to a
linked list which must be traversed on future telldir(), seekdir(),
closedir(), and readdir() calls. Applications that call telldir() for every
directory entry incur O(n^2) behavior in readdir() and O(n) in telldir() and
closedir().

This optimization eliminates the malloc() and linked list in most cases by
packing the relevant information into a single long. On 64-bit architectures
msdosfs, NFS, tmpfs, UFS, and ZFS can all use the packed representation.  On
32-bit architectures msdosfs, NFS, and UFS can use the packed
representation, but ZFS and tmpfs can only use it for about the first 128
files per directory.  Memory savings is about 50 bytes per telldir(3) call.
Speedup for telldir()-heavy directory traversals is about 20-30x for one
million files per directory.
