fork(): Defer signals and lock the heaps while _kern_fork(). * Also defer signals while registering fork hooks. * While malloc provides fork heap hooks which lock the heaps and unlock/reinit, malloc_debug provides empty hooks. * Ideas suggested by Ingo, patch reviewed by him. Thanks a lot! * Also call fork parent hooks on failure. * Solve locks-up when combining multithreading and process forking, should help with #13111.

fork: update the thread id in the pthread struct after forking Otherwise the child process's main thread will inherit the thread id of its parent and pthread operations will be directed at the wrong thread.

Introduce __set_errno() throughout libroot. * add errno_private.h, which defines the __set_errno() macro with and without tracing * instead of setting errno manually, all libroot's code now invokes __set_errno(), which makes it much easier to trace changes to errno * redirect glibc's use of __set_errno() to our own version

* Private libroot locking primitives: - Reimplemented mutex to use the _kern_mutex*() syscalls. - The initializer functions cannot fail anymore -- changed their return type to void. - Changed the initializer function semantics to not copy the name by default anymore (as in the kernel). Also added *_etc() versions of them that take an additional flags. - Added static initializer macros. - Made the mutex (and thus recursive_lock) lock functions non-interruptable. - Got rid of the "lazy" version. They are no longer needed, since the initialization of the standard types can be done statically and cannot fail. * Adjusted libroot, runtime loader, and other code using the private libroot locking primitives to the new semantics. * pthreads mutexes and condition variables: - Reimplemented using the _kern_mutex*() syscalls. - Consistently use POSIX error codes. - Fixed some not quite POSIX compliant behavior. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36323 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced the dummy implementations of the <grp.h> and <pwd.h> functions by ones reading /etc/{group,passwd}. * Added quasi-standard getpwent_r() and getgrent_r(). * Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf() constants. * Moved initgroups() and getgrouplist() definition to grp.cpp. They use the same backend as the <grp.h> functions. * Set the permissions of files created by the build system to what they should be on the image (executables: 755, others: 644). Otherwise only root could do anything under Haiku. * Added build system variables HAIKU_ROOT_USER_NAME and HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's root user. * Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage for adding additional users and groups (by default only root user and group and a "users" group are created). * Adjusted BIND port and coreutils config.h files according to what features have become available. * Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used a wrong variable name before. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24750 a95241bf-73f2-0310-859d-f6bbb57e9c96
