Regen *sysent.c after r331679 - posix_fallocate in capability mode

Sponsored by: The FreeBSD Foundation

MFC r302525,r302526:

Do allow auditing of read(2) and write(2) system calls, by assigning
those system calls audit event identifiers AUE_READ and AUE_WRITE.
While auditing file-descriptor I/O is not required by the Common
Criteria, in practice this proves useful for both live and forensic
analysis.

NB: freebsd32 already assigns AUE_READ and AUE_WRITE to read(2) and
write(2).

In process-descriptor close(2) and fstat(2), audit target process
information. pgkill(2) already audits target process ID.

Allow cpuset_{get,set}affinity in capabilities mode

MFC 313564:
Drop the "created from" line from files generated by makesyscalls.sh.

This information is less useful when the generated files are included in
source control along with the source. If needed it can be reconstructed
from the $FreeBSD$ tag in the generated file. Removing this information
from the generated output permits committing the generated files along
with the change to the system call master list without having inconsistent
metadata in the generated files.

Regenerate the affected files along with the MFC.

MFC r315526

Add clock_nanosleep()

Add a clock_nanosleep() syscall, as specified by POSIX.
Make nanosleep() a wrapper around it.

Attach the clock_nanosleep test from NetBSD. Adjust it for the
FreeBSD behavior of updating rmtp only when interrupted by a signal.
I believe this to be POSIX-compliant, since POSIX mentions the rmtp
parameter only in the paragraph about EINTR. This is also what
Linux does. (NetBSD updates rmtp unconditionally.)

Copy the whole nanosleep.2 man page from NetBSD because it is complete
and closely resembles the POSIX description. Edit, polish, and reword it
a bit, being sure to keep any relevant text from the FreeBSD page.

Regenerate syscall files.
