Include _uio.h instead of uio.h in several headers to reduce header
polution.
Fix a few places that relied on header polution to get the uio.h header.
I have not moved struct uio as many more things that use it rely on
header polution to get other definitions from uio.h.

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.
Add the POSIX header files
* arpa/inet.h
* net/if.h
* netdb.h
* netinet/in.h
* netinet/tcp.h
* sys/socket.h
* sys/syslog.h
* sys/uio.h
* sys/un.h
* syslog.h
* termios.h
and their dependencies for RTEMS. The origin of these files is the
latest FreeBSD.
