b3827d6c33 Create new module m_libcsetjmp, which wraps up uses of
__builtin_setjmp and __builtin_longjmp so that they can be selectively
replaced, on a platform by platform basis.  Does not change any
functionality.  Related to #259977.

566a25cf7e Make client sys_shmat work properly on arm-linux by taking into
account rounding requirements to SHMLBA.  Modified version of a patch
by Kirill Batuzov, batuzovk@ispras.ru.  This fixes the main bug in
#222545.  Temporarily breaks the build on all other platforms though.

578d74d4fa Fix the definedness handling of the last argument of sys_socketpair.
The last argument is really a pointer to an array of two ints and so
we need to say it is an int* and not an int [2].  This just happens to
work on amd64-linux because sizeof(int [2]) == 8 == sizeof(int*).  On
arm-linux it duly craps out w/ an assertion because sizeof(int [2]) !=
sizeof(UWord).

e6c318c531 When creating a child thread, initially set its os_state.threadgroup
to have the same value as the parent.  This avoids exit races leading
to hangs and strange behaviour in heavily multithreaded apps, in the
situation where threads are rapidly being created, and at the same
time an existing thread does sys_exit_group so as to terminate the
entire process.  Thanks to Konstantin S for chasing this down to a
small test case.  Fixes #226116.

6b95f1cd4c arm-linux: remove wrappers for __NR_ipc, __NR_mmap, __NR_sigsuspend
and __NR_sigaction, which all did I_die_here and therefore can never
have been used.  I think they were here as a result of this file being
derived from the x86-linux version, and that arm-linux uses more
modern equivalents (mmap2, rt_sig*, and the broken-out versions of
ipc).

e9de458500 Merge from branches/ARM, all parts of the ARM-Linux port except for
the changes to do with reading and using ELF and DWARF3 info.

fbf8653c8b Removed the remnants of the attempt at an ARM port, because it had
bit-rotted badly and was clogging up the code.

I put the useful remnants in docs/porting-to-ARM in case anyone ever
wants to try porting to ARM again.

d463dd2292 Removed the VGA_/VGO_/VGP_ prefixes for arch/OS/platform-specific
things.  These made sense when the arch/OS/platform-specific code was in
one module, but as that code got mixed in with generic code the boundary
between generic and non-generic blurred, and the distinction made less
sense.  So let's get rid of them.

f174930b23 Final commit for the initial modularisation pass:
- Broke part of m_scheduler off into a new module m_threadstate.  It
  contains ThreadState, VG_(threads)[] and some basic operations on the
  thread table.  All simple stuff, the complex stuff stays in m_scheduler.
  This avoids lots of circular dependencies between m_scheduler and other
  modules.

- Managed to finally remove core.h and tool.h, double hurrah!

- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
  include by every single C file.

- Lots of little cleanups and changes related to the above.

- I even did a small amount of documentation updating.
