A few days after we pushed RMHEADERS to include/Makefile, the 'upgrade'

never added to it and removed from include's Makefile.

Add them at the top of Makefile_upgrade.inc.

Varieties of pthread_get_name_np() and pthread_set_name_np() that return

These are only used for debugging but it looks like some ports want them.

I took some of the documentation from FreeBSD.

Implement the fexecve(2) system call

The fexecve(2) function is equivalent to execve(2), except that the file
to be executed is determined by the file descriptor fd instead of a
pathname.

The purpose of fexecve(2) is to enable executing a file which has been
verified to be the intended file. It is possible to actively check the
file by reading from the file descriptor and be sure that the file is
not exchanged for another between the reading and the execution.

See https://pubs.opengroup.org/onlinepubs/9699919799/functions/fexecve.html

This work is partially based on swildner's patch and FreeBSD's
implementation (revisions 177787, 182191, 238220).

XXX: We're missing O_EXEC support in open(2).

It's a standard type and more expressive.

devname(3): Remove obsolete code that queries dev.db

In the old days of static /dev, devname(3) would get the name by
querying the /var/run/dev.db created by dev_mkdb(8). Now that we have
dynamic /dev provided by devfs(5), the device name is provided by the
'kern.devname' sysctl, thus obsoleting the db query code.

I've tested to verify that the db query code isn't being used now. So
it's safe to remove this obsolete code. Cleanups to dev_mkdb(8) and
related code would follow.

Meanwhile, update the man page to reflect the current code.

Some small residue in <sys/stat.h> remains for older specs, due to the
kind of bumpy history of that header between issues 6 and 7. Namely,
struct timespec should not be defined in these cases. But this is good
enough for now.
