c7461d15cd Replace is_inuse_bszB() with is_inuse_block(), which is higher-level 
and thus makes the code that uses it easier to understand.

2aa48b8c3a Another seemingly-small but critical change imported from 2.4.0-ppc: 
don't read symbols from sections with w permissions.  For some reason
ppc-linux maps executables three times, not twice as on x86, and if
the w flag is ignored, we wind up reading debug info twice, getting
wrong redirections, and then it all goes to hell in a handbasket.

a self-checking translation.

50773ee7a1 Support for self modifying code on unfriendly platforms (x86, amd64) 
via the use of self-checking translations.  (Friendly platforms which
have icache-invalidation instructions we can observe, such as ppc32,
are already handled correctly.)  This should finally fix the
longstanding problem of V incorrectly handling calls of statically
nested functions (a gcc extension), and more generally make it a lot
easier to use V to debug dynamic code generation systems.

Since self-checking is a large performance overhead, there is some
control via a command line flag:

   --smc-support=none 

      Don't make any translations self-checking.

   --smc-support=stack

      Add checking code for translations taken from segments which
      have the SF_GROWDOWN flag set -- stacks, basically.
      This is the default.  It should make gcc nested functions and
      GNU Ada work correctly with no intervention from the user.

   --smc-support=all

      Make all translations self-checking.  This is expensive and 
      you want to do this if you're debugging a JIT compiler or
      some such.

fcf186b9c8 Sort out the mess that is pread64/pwrite64 properly. All three platforms 
that we currently support use the same handlers in the kernel without any
platform specific wrappers.

The final argument is a 64 bit argument however, which means that it
requires two registers on x86 and ppc32 and only one on amd64. The
reason it works in the kernel is that x86 and ppc32 calling conventions
inside the kernel work out correctly and the values get joined together.

For our purposes we make x86 and ppc32 use the generic veneer with
five arguments and amd64 use a platform specific one with four...

e67b65d0eb Changed m_hashtable.c to allow the size of the hash table to be specified 
when it is created.  Fortunately this didn't affect code outside this
module except for the calls to VG_(HT_construct)().

As a result, we save some memory because not all tables have to be as big
as the ones needed for malloc/free tracking.

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.
