POSIX requires SIGTTOU to be sent to a process in a background process
group that tries to change the foreground process group ID associated
with its controlling terminal, unless the process is ignoring SIGTTOU or
the calling thread is blocking it. Previously the code checked the
former condition but not the latter, making it possible for calls to
tcsetpgrp() to get stuck in a loop and never return.
Should fix#3417.

This commit replaces the placeholder implementation of sbrk(), which
operated on a process' heap, with real implementations of brk() and
sbrk() that adjust a process' program break.
* unistd.h: Add standard definitions of brk() and sbrk(); include
stdint.h for intptr_t.
* thread.cpp: Recognize RLIMIT_AS and RLIMIT_DATA resource limits
(both currently unlimited); order limit identifiers alphabetically.
* arch-specific.cpp: Remove sbrk_hook().
* malloc_debug_api.cpp: Remove sbrk_hook().
* unistd/Jamfile: Build brk.c instead of sbrk.c.
* unistd/brk.c: Add.
* unistd/sbrk.c: Delete (placeholder implementation).
* libroot_stubs.c: Remove sbrk_hook().
* libroot_stubs_legacy.c: Remove sbrk_hook().
* src/tests/.../posix/Jamfile: Build brk_test.c.
* brk_test.c: Add (simple unit test that demonstrates behaviour of
sbrk()).

Reduce duplication of code by
* Removing from elf_common.h definitions available in os/kernel/elf.h
* Deleting elf32.h and elf64.h
* Renaming elf_common.h to elf_private.h
* Updating source to build using public and private ELF header files
together

Make a version of elf.h (assembled from the private header files
elf_common.h, elf32.h and elf64.h, and including Haiku's extensions for
C++) available to applications ported from UNIX.

This adds to the "unittests" target a dependency on the
"AppTestRunApp3a" (etc.) files meant to be copied as part of the
BApplication test suite so they are generated when "jam unittests" is
run.
* TestsRules: Add "UnitTestDependency" rule.
* testapps/Jamfile: Make unit tests depend on copied files.
Fixes#12441.

The use of an unreliable test for relocatability effectively broke
runtime_loader's support for non-position-independent executables, as it
would insist on randomly positioning these files' segments in memory
anyway causing the program to quickly crash.
With this change runtime_loader uses the object type specified in the
file's header to determine whether its segments can be safely relocated,
restoring support for non-PI executables.
Fixes#12427.
