Remove workaround for ancient HTML generation code.

Use .Fn to refer functions instead of .Nm.

Fix spelling of "includes".

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Sort errors. Use parentheses instead of Pq in normal text.

Rewrite for clarity and add an example.

As discussed in tech-kern, provide the means to prevent delivery of SIGPIPE
on EPIPE for all file descriptor types:

- provide O_NOSIGPIPE for open,kqueue1,pipe2,dup3,fcntl(F_{G,S}ETFL) [NetBSD]
- provide SOCK_NOSIGPIPE for socket,socketpair [NetBSD]
- provide SO_NOSIGPIPE for {g,s}seckopt [NetBSD/FreeBSD/MacOSX]
- provide F_{G,S}ETNOSIGPIPE for fcntl [MacOSX]

Consistently mark up defined values with Dv.

Note that dup2(2) and dup3(2) may not fail with EMFILE; from PR lib/45148.

mention EINVAL.

Small markup glitch.

Various minor improvements.

* Arrange for interfaces that create new file descriptors to be able to
  set close-on-exec on creation (http://udrepper.livejournal.com/20407.html).

    - Add F_DUPFD_CLOEXEC to fcntl(2).
    - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing.
    - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter
      for socket(2) and socketpair(2).
    - Add new paccept(2) syscall that takes an additional sigset_t to alter
      the sigmask temporarily and a flags argument to set SOCK_CLOEXEC,
      SOCK_NONBLOCK.
    - Add new mode character 'e' to fopen(3) and popen(3) to open pipes
      and file descriptors for close on exec.
    - Add new kqueue1(2) syscall with a new flags argument to open the
      kqueue file descriptor with O_CLOEXEC, O_NONBLOCK.

* Fix the system calls that take socklen_t arguments to actually do so.

* Don't include userland header files (signal.h) from system header files
  (rump_syscallargs.h).

* Bump libc version for the new syscalls.

Document the behavior of dup2 when oldfd == newfd: nothing happens.
Suggested by the patches in PR bin/36551 from Greg A. Woods.

\- is a minus, not -.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Use
.In header.h
instead of
.Fd #include \*[Lt]header.h\*[Gt]
Much easier to read and write, and supported by groff for ages.
Okayed by ross.

Sort sections, sort SEE ALSO, punctuation and miscellanous fixes.

Boring whitespace fixes.

Pull up to last week's -current.

Add a LIBRARY section to system call manual pages.  While it's clear that the
libraries contain stubs only (with minor exceptions a la pipe(2)), the purpose
of this section is to provide linkage information.

Last of the .Os cleanups.  .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages.  Wheee!

first pass at fixing up capitalization of function names and
arguments; ensure that each is correct with respect to the
implementation, rather than being correct as per english.

Add missing `STANDARDS' compliance statements.  As we #define _POSIX_VERSION
to 199009L, bump existing statements to 1003.1-1990.

getdtablesize(2) -> getdtablesize(3)

Update standards conformance.

merge with lite, keeping most local changes.  clean up Ids

from Lite

Clean up manpages:
  Use .Fn rather than .Nm macro in HISTORY and STANDARDS sections.
  Use .At and .St macros instead of spelling out "Version 6 UNIX",
	"IEEE 1003.1-1988 (POSIX)", etc.

Add RCS indentifiers.
