Make sysconf(_SC_PAGESIZE) return the value from getpagesize(3).
That avoids a syscall - getpagesize(3) gets the value from the ELF
aux strings.

Clean up the vcs ID strings in libc's gen/ directory.

- Move CSRG IDs into __SCCSID().
- When a file has been copied, consistently use 'From: <tag>' for strings
referencing the version of the source file copied from in the license
block comment.
- Some of the 'From:' tags were using $FreeBSD$ that was being expanded on
each checkout. Fix those to hardcode the FreeBSD tag from the file that
was copied at the time of the copy.
- When multiple strings are present list them in "chronological" order,
so CSRG (__SCCSID) before FreeBSD (__FBSDID). If a file came from
OtherBSD and contains a CSRG ID from the OtherBSD file, use the order
CSRG -> OtherBSD -> FreeBSD.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Report _SC_SEM_NSEMS_MAX and _SC_SEM_VALUE_MAX which show parameters
of the current usermode implementation of the POSIX semaphores.

For NSEMS_MAX, return -1 without changing errno, which indicates that
the variable has no limit. Before, sysconf(3) returned parameters
queried from the ksem(9) legacy implementation, which apparently has
low defaults for NSEMS_MAX.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

MFH @r292599

This includes the pluggable TCP framework and other chnages to the
netstack to track for VNET stability.

Security: The FreeBSD Foundation

libc: Use namespace.h in a few more files.

libc now no longer calls fstat(), socketpair() and wait(), only the
underscore-prefixed versions (_waitpid() instead of wait()).
