More tweaks to the libbsd.so compatibility library: * added sigsetmask(), and sigblock() * added ALIGN(), ALIGNBYTES, and howmany() macros git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19493 a95241bf-73f2-0310-859d-f6bbb57e9c96

/*
Updated posix headers to remove commas from copyright line, to match the preferred coding guidelines. Cleaned up some header style violations, making sure there are two blank lines after the header guards. This fixes the bsd header part of #2191. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39291 a95241bf-73f2-0310-859d-f6bbb57e9c96

#ifndef _BSD_SIGNAL_H_

#include_next <signal.h>
Add a features.h to auto enable _DEFAULT_SOURCE Unless __STRICT_ANSI__ is defined (as it is when running the compiler in --std=c89 or --std=c99, but not when running it without any specific args), we can enable these by default and behave like most other systems. I don't know why no one has done this yet despite suggesting it multiple times and people prefer to #define _BSD_SOURCE manually everywhere. Remove all places in our Jamfiles and sources where it had been defined. _DEFAULT_SOURCE is now enabled by default for all sources of Haiku, since we let the compiler use GNU extensions (no strict C standard specified on command line) Use _DEFAULT_SOURCE as the define name to match current versions of glibc. Enable it if _BSD_SOURCE is #defined in compiler flags, for backward compatibility.

#ifdef _DEFAULT_SOURCE
Protect all BSD extensions with _BSD_SOURCE * Do not define the symbols by default, as they are not in the default libraries. * Adjust jamfiles of all code using BSD extensions to define _BSD_SOURCE. * This makes Haiku slightly more compliant to standard C/POSIX.

* Added BSD specific errno.h for EDOOFUS (yeah, I know, great error code...) * Added sigmask() macro. * Fixed libutil.h I broke yesterday: it's thought to add functions only if you've included some other headers before; added the correct header guard we're using for our sys/param.h. * Added pidfile.c to the build. * Fixed warning in realhostname.c, and pidfile.c. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23840 a95241bf-73f2-0310-859d-f6bbb57e9c96
